During the mid-1980s, when Hainan Island was still part of Guangdong Province, a fourteen-month episode of marketing zeal by Hainan Special District Administrator Lei Yu put Hainan's pursuit of provincial status under a cloud. It involved the duty-free imports from Hong Kong of 90,000 Japanese-made cars and trucks at a cost of ¥ 4.5 billion (US$ 1.5 billion), and exporting them – with

The twinning of towns and cities is sometimes done for political purposes. The Hungarian city Gyöngyös was twinned with the Azerbaijani city of Shusha in 2013, signing the twinning agreement with representatives from the Azerbaijani government; Hungary recognised Shusha as de jure part of Azerbaijan , even though it

IR emerged as a formal academic discipline in 1919 with the founding of the first IR professorship: the Woodrow Wilson Chair at Aberystwyth , University of Wales (now Aberystwyth University ), held by Alfred Eckhard Zimmern and endowed by David Davies . International politics courses were established at the University of Wisconsin in 1899 by Paul Samuel Reinsch and at Columbia University in 1910. By 1920, there were four universities that taught courses on international organization . Georgetown University 's Walsh School of Foreign Service

The purpose of twinnings was then expanded to encourage trade and tourism or to reflect other links, such as towns sharing the same name or migration links. By the 2000s, town twinning became increasingly used to form strategic international business links among member cities, and may include localities of any scope such as villages, prefectures, or countries.

Not all approaches to regime theory, however, are liberal or neoliberal; some realist scholars like Joseph Grieco have developed hybrid theories which take a realist based approach to this fundamentally liberal theory. (Realists do not say cooperation never happens, just that it is not the norm; it is a difference of degree). The constructivist framework rests on the fundamental assumption that

A state wherein the nation is sovereign would thence be termed a nation-state, as opposed to a monarchy or a religious state; the term republic increasingly became its synonym. An alternative model of the nation-state was developed in reaction to the French republican concept by the Germans and others, who instead of giving the citizenry sovereignty, kept the princes and nobility, but defined nation-statehood in ethnic-linguistic terms, establishing

In the case of Sutton this is in a separate smaller painting (above its main one) showing a beech tree, intended as a symbol of prosperity and from which Carshalton Beeches in
2533-623: A purely anarchical system. Rather, liberal theory assumes that states are institutionally constrained by the power of international organisations, and mutually dependent on one another through economic and diplomatic ties. Institutions such as the United Nations , the World Trade Organisation (WTO), and the International Court of Justice are taken to, over time, have developed power and influence to shape
2682-583: A school dedicated to teaching international affairs, was founded in Geneva , Switzerland. This was rapidly followed by establishment of IR at universities in the US. The creation of the posts of Montague Burton Professor of International Relations at LSE and at Oxford gave further impetus to the academic study of international relations. Furthermore, the International History department at LSE developed

Constructivism is also present in the analysis of international law , where norms of conduct such as the prohibition of chemical weapons , torture , and the protection of civilians in war , are socialised into international organisations, and stipulated into rules. Prominent constructivist IR scholars include Michael Barnett , Martha Finnemore , Ted Hopf , Peter Katzenstein , Kathryn Sikkink , and Alexander Wendt . Post-structuralism theories of international relations (also called critical theories due to being inherently critical of traditional IR frameworks) developed in
2980-649: A sister city relationship with Taipei . In November 2020, U.S. senator Marsha Blackburn introduced legislation, the Sister City Transparency Act, to provide federal oversight to mitigate risks of sister city agreements being used for political influence campaigns. In 2024, Indiana banned localities from entering into sister city agreements with six "foreign adversary" countries.

Such a foundation of sovereignty is indicated by a sovereign's obligation to other sovereigns, interdependence and dependence to take place. While throughout world history there have been instances of groups lacking or losing sovereignty, such as African nations prior to decolonization or
3427-555: A subdiscipline of political science, the focus of IR studies lies on political, diplomatic and security connections among states, as well as the study of modern political world history. In many academic institutions, studies of IR are thus situated in the department of politics/social sciences. This is for example the case in Scandinavia, where international relations are often simply referred to as international politics (IP). In institutions where international relations refers to

For example, in the 1990s, when the Nottingham City Council in the UK considered installing a tram network, it consulted experts from its twin city of Karlsruhe , which has one of the most extensive and efficient tram networks in Germany. With assistance from Karlsruhe's specialist engineers, Nottingham completed its second tram line in 2013. In 2014, Bristol and New Orleans announced their intention to form

By this he means that the anarchic structure that realists claim governs state interaction is in fact a phenomenon that is socially constructed and reproduced by states. Constructivism is part of critical theory, and as such seeks to criticise the assumptions underlying traditional IR theory. Constructivist theory would for example claim that the state leaders of the United States and Soviet Union were socialised into different roles and norms, which can provide theoretical insights to how

The Hainan partridge , white-eared night heron , Hainan leaf warbler , and yellow-billed nuthatch are endemic to
6854-409: The "critical" component of theory was derived significantly from their attempt to overcome the limits of positivism. Modern-day proponents such as Andrew Linklater , Robert W. Cox , and Ken Booth focus on the need for human emancipation from the nation-state. Hence, it is "critical" of mainstream IR theories that tend to be both positivist and state-centric. Further linked in with Marxist theories

Post-structuralism explores the deconstruction of concepts traditionally not problematic in IR (such as "power" and "agency") and examines how the construction of these concepts shapes international relations. The examination of "narratives" plays an important part in poststructuralist analysis; for example, feminist poststructuralist work has examined
7152-443: The 1990s opened up a space for gendering International Relations. Because feminist IR is linked broadly to the critical project in IR, by and large most feminist scholarship have sought to problematize the politics of knowledge construction within the discipline—often by adopting methodologies of deconstructivism associated with postmodernism/poststructuralism. However, the growing influence of feminist and women-centric approaches within

11473-545: The first graduate-only school of international affairs in the United States. In 1965, Glendon College and the Norman Paterson School of International Affairs were the first institutions in Canada to offer an undergraduate and a graduate program in international studies and affairs, respectively. The lines between IR and other political science subfields is sometimes blurred, in particular when it comes to
11622-647: The first fully-fledged international system. Analyses of the foreign policies of sovereign city states have been done in ancient times, as in Thycydides ' analysis of the causes of the Peloponnesian War between Athens and Sparta , as well as by Niccolò Machiavelli in The Prince , published in 1532, where he analyzed the foreign policy of the renaissance city state of Florence . The contemporary field of international relations, however, analyzes
11771-524: The first international relations graduate program in the United States. This was soon followed by the establishment of the Committee on International Relations (CIR) at the University of Chicago , where the first research graduate degree was conferred in 1928. The Fletcher School of Law and Diplomacy , a collaboration between Tufts University and Harvard University , opened its doors in 1933 as
11920-520: The foreign policies of individual states. Furthermore, the existence of the globalised world economy makes continuous military power struggle irrational, as states are dependent on participation in the global trade system to ensure their own survival. As such, the liberal framework stresses cooperation between states as a fundamental part of the international system. States are not seen as unitary actors, but pluralistic arenas where interest groups, non-governmental organisations, and economic actors also shape
12069-469: The form of dependence. A prominent derivative of Marxian thought is critical international relations theory which is the application of " critical theory " to international relations. Early critical theorists were associated with the Frankfurt School , which followed Marx's concern with the conditions that allow for social change and the establishment of rational institutions. Their emphasis on
12218-551: The fundamental assumption that the international state system is an anarchy , with no overarching power restricting the behaviour of sovereign states. As a consequence, states are engaged in a continuous power struggle, where they seek to augment their own military capabilities, economic power, and diplomacy relative to other states; this in order to ensure the protection of their political system, citizens, and vital interests. The realist framework further assumes that states act as unitary, rational actors, where central decision makers in
12367-555: The genocide in 2016, some twin agreements such as Edirne – Haskovo were terminated by Turkey. China manages sister city relationships through the Chinese People's Association for Friendship with Foreign Countries (CPAFFC). In April 2019, CPAFFC president Li Xiaolin said, “Friendship city relations have become one of the important channels to implement the Belt and Road Initiative .” In January 2020, Shanghai canceled its sister city relationship with Prague after Prague's mayor signed
12516-449: The help of local naval units – to the mainland, making 150% profits. By comparison, only 10,000 vehicles were imported into Hainan since 1950. In addition, it involved further consignments of 2.9 million TV sets, 252,000 videocassette recorders & 122,000 motorcycles. The money was taken from the 1983 central government funds destined for the construction of the island's transportation infrastructure (roads, railways, airports, harbors) over
12665-530: The inaugural issue of World Politics , Frederick S. Dunn wrote that IR was about "relations that take place across national boundaries" and "between autonomous political groups in a world system". Dunn wrote that unique elements characterized IR and separated it from other subfields: international politics is concerned with the special kind of power relationships that exist in a community lacking an overriding authority; international economics deals with trade relations across national boundaries that are complicated by
12814-595: The indigenous Hlai people fought a vigorous guerrilla campaign against the Japanese, who were only able to occupy some Hainan territories; but in retaliation the Japanese launched numerous massacres against Hlai villages. Feng Baiju led the Hainan Independent Column of fighters throughout the 1930s and 1940s. After the Japanese surrender in 1945, the Kuomintang reestablished control. Hainan
12963-851: The international policy communities (for example at the World Bank and the United Nations) is more reflective of the liberal feminist emphasis on equality of opportunity for women. Prominent scholars include Carol Cohn , Cynthia Enloe , Sara Ruddick , and J. Ann Tickner . International society theory, also called the English school, focuses on the shared norms and values of states and how they regulate international relations. Examples of such norms include diplomacy, order, and international law . Theorists have focused particularly on humanitarian intervention, and are subdivided between solidarists, who tend to advocate it more, and pluralists, who place greater value in order and sovereignty. Nicholas Wheeler
13112-492: The international system could remain stable in the absence of a hegemon, thus rebutting hegemonic stability theory. Regime theory is derived from the liberal tradition that argues that international institutions or regimes affect the behaviour of states (or other international actors). It assumes that cooperation is possible in the anarchic system of states, indeed, regimes are by definition, instances of international cooperation. While realism predicts that conflict should be
13261-425: The international system is anarchic, and states pursue their self interest). Liberal institutionalists highlight the role of international institutions and regimes in facilitating cooperation between states. Prominent neoliberal institutionalists are John Ikenberry , Robert Keohane , and Joseph Nye . Robert Keohane's 1984 book After Hegemony used insights from the new institutional economics to argue that
13410-545: The international system is built on social constructs; such as ideas , norms , and identities . Various political actors, such as state leaders , policy makers , and the leaders of international organisations, are socialised into different roles and systems of norms, which define how the international system operates. The constructivist scholar Alexander Wendt , in a 1992 article in International Organization , noted in response to realism that "anarchy
13559-443: The island as well, including the economically significant black pepper ( Piper nigrum ). At least 25-30 species belonging to the order Zingiberales grow on Hainan, including numerous types of ginger , galangal , canna , turmeric ( Curcuma sp.) and prayer-plants ( Marantaceae ), among others. Coconuts ( Cocos sp.) are a fairly common sight along the coastline. Trees found on Hainan include at least 18 species of Ficus ,
13708-467: The island between 7000–27,000 years ago. Hainan Island was recorded by Chinese officials in 110 BC, when the Western Han dynasty established a military garrison there following the arrival of General Lu Bode . The process of sinicization in Hainan was driven by the conjunction of Han territorial expansion and the arrival of Han Chinese military and administrative personnel who settled on
13857-747: The island include such animals as frogs , toads , geckos , skinks , and butterflies ; as with many adjacent tropical regions, the Arthropoda and invertebrates are well-represented here, with mosquitoes naturally being very common at certain times of the year. The swarms of biting, flying insects actually play a key role in island food chains and ecosystems , not only being consumed by many other species (such as bats and birds ) but serving as pollinators for many types of flowering plants . Hainan's lakes and waterways are populated with various freshwater fishes, such as carp and catfish , whose fry readily consume both mosquito eggs and larvae (laid on
14006-586: The island. Secretive, and sometimes less commonly seen, are the snakes , such as the Asian palm pit viper , the red bamboo snake , and cobras. In the seas surrounding Hainan, sea turtles and whale sharks are regular visitors. Hainan island has rich bio-diversity of cetaceans and is the site of studying these in Chinese waters. Many whales such as North Pacific right whales , western gray whales , humpback whales , and blue whales (all of these are almost extinct in Chinese waters) were historically seen in
14155-419: The island. Over the course of many centuries, dynastic Chinese ruling authorities exiled individuals condemned by the imperial courts as criminals or political dissidents were frequently banished to Hainan island and northern Vietnam, regions that were both integral parts governed typically under the jurisdiction of Guangdong province during different Chinese dynasties, where they were subjected to harsh labor in
14304-455: The island. The South China-Vietnam subtropical evergreen forests cover the lowlands, and extend onto the adjacent mainland. The Hainan Island monsoon rainforests covers the interior of the island, and includes montane rain forests with a more seasonal climate and more deciduous trees. The majority of Hainan's land area is covered in forest, with 61.5% total coverage. At the end of 2012, nearly 210,000 hectares (518,921 acres) of forest-cover
14453-459: The main island, the flora, fauna, and the climate are very similar. A number of small islands, which are located hundreds of kilometers to the south, are claimed and administered by Sansha as part of Hainan Province. Sovereignty of these islands is however disputed. These islands include: Compared to most of mainland China, the air quality of Hainan is significantly better since it is not affected by factory pollution, which has adversely affected
14602-654: The modern concept of town twinning appeared during the Second World War. More specifically, it was inspired by the bombing of Coventry on 14 November 1940, known as the Coventry Blitz . First conceived by the then Mayor of Coventry , Alfred Robert Grindlay , culminating in his renowned telegram to the people of Stalingrad (now Volgograd ) in 1942, the idea emerged as a way of establishing solidarity links between cities in allied countries that went through similar devastating events. The comradeship between
14751-492: The motto: "Only Paris is worthy of Rome; only Rome is worthy of Paris." Within Europe, town twinning is supported by the European Union. The support scheme was established in 1989. In 2003 an annual budget of about € 12 million was allocated to about 1,300 projects. The Council of European Municipalities and Regions also works closely with the commission (DG Education and Culture) to promote modern, high quality twinning initiatives and exchanges that involve all sections of
14900-505: The next ten years. On 1 October 1984, it became the Hainan Administrative Region ( 海南行政区 ), with its own People's Government, and finally as a province separate from Guangdong four years later. In 1988, when the island was made a separate province, it was designated a Special Economic Zone in an effort to increase investment. The central government funds were deemed insufficient by the Hainan authorities for
15049-442: The norm in international relations, regime theorists say that there is cooperation despite anarchy. Often they cite cooperation in trade, human rights and collective security among other issues. These instances of cooperation are regimes. The most commonly cited definition of regimes comes from Stephen Krasner , who defines regimes as "principles, norms, rules, and decision-making procedures around which actor expectations converge in
15198-563: The northern coast of Hainan Island, while Sanya is a well-known tourist destination on the southern coast. The other major cities are Wenchang , Sansha , Qionghai , Wanning , Wuzhishan , Dongfang and Danzhou . According to China's territorial claims , several disputed territories in the South China Sea , including the Spratly Islands ( Nansha ) and Paracel Islands ( Xisha ), are administered under Sansha city of
15347-525: The number of China's sister city relationships doubled. More than one-third of Chinese sister city relationships are with sister cities in the east Asia Pacific region. Town twinning is supported in Japan by the Council of Local Authorities for International Relations , a joint agency of local governments established by the Japanese government in 1988 (similar to Sister Cities International , its counterpart in
15496-466: The occupation of Iraq during the Iraq War , there is still a need for sovereignty in terms of assessing international relations. The concept of power in international relations can be described as the degree of resources, capabilities, and influence in international affairs. It is often divided up into the concepts of hard power and soft power , hard power relating primarily to coercive power, such as
15645-707: The pronunciation of its name in the local Hainanese dialect. According to some scholars, Hainan was originally attached to the Northeastern part of what is now Vietnam ; however, the island was formed after it physically broke away from Vietnam due to a volcanic eruption and drifted southeast near China after the Mesozoic , millions of years ago. The Baiyue people are among the earliest Kra-Dai residents to arrive on Hainan island. They are believed to have settled there at least two to six thousand years ago, and carry genetic markers from ancient people who reached
15794-525: The province were 34,000 tons in 2012, a 3 percent year-on-year reduction. In 2011, smog emissions were reduced 6.3 percent to 15,000 tons. Protected areas include the Yinggeling -Limushan and Wuzhishan -Diaoluoshan nature reserves. The climate of Hainan is mostly tropical. The island's two largest cities, Haikou and Sanya , both possess a tropical Köppen climate . The annual average temperature ranges from 23 to 28 °C (73 to 82 °F), Haikou
15943-595: The province. While the Paracels are fully under China's control, many of the Spratly Islands are controlled by other countries, such as Vietnam and the Philippines . In 2020, a large-scale plan was announced by the Chinese government to transform the entire island province into a free trade port , with the aim of turning it into the largest free-trade port in the world by 2035. The plan involves building
16092-409: The rarely if ever fulfilled ideal that all people speaking one language should belong to one state only. The same claim to sovereignty was made for both forms of nation-state. In Europe today, few states conform to either definition of nation-state: many continue to have royal sovereigns, and hardly any are ethnically homogeneous. The particular European system supposing the sovereign equality of states
16241-477: The real-world problems that international relations studies is supposed to contribute to solving. Constructivist theory (see above) is the most prominent strand of post-structuralism. Other prominent post-structuralist theories are Marxism, dependency theory, feminism, and the theories of the English school. See also Critical international relations theory . Marxist theories of IR reject the realist/liberal view of state conflict or cooperation; instead focusing on
16390-473: The realist philosophy. However, while their work may support realist doctrine, it is not likely that they would have classified themselves as realists in this sense. Political realism believes that politics, like society, is governed by objective laws with roots in human nature . To improve society, it is first necessary to understand the laws by which society lives. The operation of these laws being impervious to our preferences, persons will challenge them only at
16539-407: The relations of these different types of states is disputed. "Levels of analysis" is a way of looking at the international system, which includes the individual level, the domestic state as a unit, the international level of transnational and intergovernmental affairs, and the global level. What is explicitly recognized as international relations theory was not developed until after World War I , and
16688-403: The relationship between the institutionalization of IR as an academic discipline and the demands of national governments. Robert Vitalis [ ar ] 's book White World Order, Black Power Politics details the historical imbrication of IR in the projects of colonial administration and imperialism, while other scholars have traced the emergence of international relations in relation to
16837-443: The risk of failure. Realism, believing as it does in the objectivity of the laws of politics, must also believe in the possibility of developing a rational theory that reflects, however imperfectly and one-sidedly, these objective laws. It believes also, then, in the possibility of distinguishing in politics between truth and opinion—between what is true objectively and rationally, supported by evidence and illuminated by reason, and what
16986-419: The role that "women" play in global society and how they are constructed in war as "innocent" and "civilians". Rosenberg's article "Why is there no International Historical Sociology" was a key text in the evolution of this strand of international relations theory. Post-structuralism has garnered both significant praise and criticism, with its critics arguing that post-structuralist research often fails to address
17135-695: The sea to be condensed into fog. The fog remains from day to night, and is evenly distributed. Visibility may be reduced to 50 meters (160 ft) for days at a time. During this period, residents normally keep windows shut. The moisture in the air is so extreme that the walls in homes weep, and floors often accumulate a layer of water. Hainan has over 1,500 km (580 sq mi) of tropical forest, in which can be found over 4,600 types of plants and more than 570 species of animals. The nature observation database iNaturalist.org currently lists 6,687 species of plants, animals and fungi as having been observed on Hainan Island (in 2024). In modern times, however,
17284-558: The small island's natural balance has been threatened, largely due to the introduction of exotic species , as well as human impacts from tourism , deforestation , and the use of herbicides , pesticides and other such pollutants . A report from the Department of Land, Environment and Resources of Hainan Province states that 200 species are near extinction, with six plant species, such as Maytenus hainanensis and Sciaphila tenella , having been declared extinct. Two ecoregions cover
17433-444: The special district. In June 2020, China announced a master plan for Hainan's free trade port system. Announced by state-owned media Xinhua News Agency, Hainan will "basically establish a free trade port system by 2025 and become more mature by 2035." South China Morning Post described such an initiative as an effort of PRC to "replace Hong Kong as the trading entrepôt" while Cheng Shi of ICBC International has refused to accept such
17582-420: The state apparatus ultimately stand for most of the state's foreign policy decisions. International organizations are in consequence merely seen as tools for individual states used to further their own interests, and are thought to have little power in shaping states' foreign policies on their own. The realist framework is traditionally associated with the analysis of power-politics, and has been used to analyze
17731-513: The study of conflict , institutions , political economy and political behavior . The division between comparative politics and international relations is artificial, as processes within nations shape international processes, and international processes shape processes within states. Some scholars have called for an integration of the fields. Comparative politics does not have similar " isms " as international relations scholarship. Critical scholarship in international relations has explored
17880-530: The systemic level of international relations is often, but not always, the preferred method for neo-realists and other structuralist IR analysts. Preceding the concepts of interdependence and dependence, international relations relies on the idea of sovereignty. Described in Jean Bodin 's Six Books of the Commonwealth in 1576, the three pivotal points derived from the book describe sovereignty as being
18029-482: The term "ciudades hermanadas", which means "sister cities". Germany, Poland, and the Czech Republic each use Partnerstadt (German), miasto partnerskie (Polish) and partnerské město (Czech), which translate as "partner town" or "partner city". France uses ville jumelée (jumelage, twinned town or city), and Italy has gemellaggio (twinning) and comune gemellato (twinned municipality). In
18178-520: The term "sister cities" or "twin cities". In China, the term is 友好城市 (yǒuhǎo chéngshì – friendly cities). Sometimes, other government bodies enter into a twinning relationship, such as the agreement between the provinces of Hainan in China and Jeju in South Korea. The Douzelage is a town twinning association with one town from each of the member states of the European Union. Though
18327-453: The term is often used interchangeably with the term "friendship city", this may mean a relationship with a more limited scope in comparison to a sister city relationship, and friendship city relationships are mayor-to-mayor agreements. City diplomacy is a form of paradiplomacy that involves discussions between officials and residents of different cities. Often these cities will be located in different countries. As such, city diplomacy involves
18476-422: The territory's sovereign borders. These principles underpin the modern international legal and political order. The period between roughly 1500 to 1789 saw the rise of independent sovereign states , multilateralism , and the institutionalization of diplomacy and the military. The French Revolution contributed the idea that it was the citizenry of a state, defined as the nation, that were sovereign, rather than
18625-486: The traditional focus of IR on states, wars, diplomacy and security, but feminist IR scholars have also emphasized the importance of looking at how gender shapes the current global political economy. In this sense, there is no clear cut division between feminists working in IR and those working in the area of International Political Economy (IPE). From its inception, feminist IR has also theorized extensively about men and, in particular, masculinities. Many IR feminists argue that
18774-490: The tropical climate as a form of punishment. One of the most famous exiled individuals was Su Shi , a well-known intellectual, poet, and politician of the Song era, who offended many of his colleagues and superiors in the royal court. Shi wrote extensively about his exiled experiences on the island during the 11th century AD. After the 11th century AD, large numbers of Han Chinese people from Fujian and Guangdong began migrating to
18923-415: The turn of the millennium that it became much more common. The first priority of those carrying out city diplomacy typically overlaps with the core aims of municipal government – improving the lives of local residents. Yet they will often collaborate with peers in other cities to work on issues of planet-wide concern, such as efforts to address climate change . The phrase "city diplomacy" is formally used in
19072-696: The two cities continued, when again in response to the Battle of Stalingrad , 830 women in Coventry – led by the subsequent Mayor Emily Smith – had their names embroidered on a tablecloth along with the words "Little help is better than a lot of pity" and sent it, along with money (each donated six pence), to the people of Stalingrad. The tablecloth can now be seen at the Panorama Museum of the Battle of Stalingrad. The twinning between Coventry and Stalingrad
19221-461: The uncontrolled actions of sovereign states; and international law is law that is based on voluntary acceptance by independent nations. The terms "International studies" and " global studies " have been used by some to refer to a broader multidisciplinary IR field. Studies of international relations started thousands of years ago; Barry Buzan and Richard Little considered the interaction of ancient Sumerian city-states, starting in 3,500 BC , as
19370-443: The use of force, and soft power commonly covering economics , diplomacy , and cultural influence. However, there is no clear dividing line between the two forms of power.

Hainan Island measures 288 km (179 mi) long and 180 km (110 mi) wide. The northern half of Hainan is covered with the ancient Hainan Volcanic Field . Beneath the topsoil is volcanic rock while the topsoil itself contains small pieces of this vesicular rock. Wetland covers 320,000 hectares, 78,000 hectares of which were created artificially. Most of this
19817-521: The winter and spring to mate and calve. These gentle giants of the sea had been hunted heavily and were wiped out by Japanese whalers (established whaling stations on various sites on Chinese and Korean coasts including Hainan and Daya Bay ). A few Bryde's whales and minke whales may still occur in the adjacent waters along with on Leizhou Peninsula and the Gulf of Tonkin . Smaller species of whale and dolphins , such as short-finned pilot whales and pantropical spotted dolphins , but most notably
19966-825: The workings of the United Cities and Local Governments and the C40 Cities Climate Leadership Group , and is recognised by the USC Center on Public Diplomacy . A March 2014 debate in the British House of Lords acknowledged the evolution of town twinning into city diplomacy, particularly in matters of trade and tourism, but also in culture and post-conflict reconciliation. The importance of cities developing "their own foreign economic policies on trade, foreign investment, tourism and attracting foreign talent" has also been highlighted by
20115-493: The workings of the international system. The intellectual basis of liberal theory is often cited as Immanuel Kant 's essay Perpetual Peace from 1795. In it, he postulates that states, over time, through increased political and economic cooperation, will come to resemble an international federation—a world government ; which will be characterised by continual peace and cooperation. In modern times, liberal international relations theory arose after World War I in response to
20264-584: Was based on a vaguely hierarchical religious order. Contrary to popular belief, Westphalia still embodied layered systems of sovereignty, especially within the Holy Roman Empire . More than the Peace of Westphalia, the Treaty of Utrecht of 1713 is thought to reflect an emerging norm that sovereigns had no internal equals within a defined territory and no external superiors as the ultimate authority within
20413-656: Was between Paderborn , Germany, and Le Mans , France, in 836. Starting in 1905, Keighley in West Yorkshire, England, had a twinning arrangement with French communities Suresnes and Puteaux . The first recorded modern twinning agreement was between Keighley and Poix-du-Nord in Nord, France, in 1920 following the end of the World War I . This was initially referred to as an adoption of the French town; formal twinning charters were not exchanged until 1986. The practice
20562-521: Was continued after the Second World War as a way to promote mutual understanding and cross-border projects of mutual benefit. For example, Coventry twinned with Stalingrad and later with Dresden as an act of peace and reconciliation, all three cities having been heavily bombed during the war. The city of Bath formed an " Alkmaar Adoption committee" in March 1945, when the Dutch city was still occupied by

20860-543: Was exported to the Americas, Africa, and Asia via colonialism and the "standards of civilization". The contemporary international system was finally established through decolonization during the Cold War . However, this is somewhat over-simplified. While the nation-state system is considered "modern", many states have not incorporated the system and are termed "pre-modern". A handful of states have moved beyond insistence on full sovereignty, and can be considered "post-modern". The ability of contemporary IR discourse to explain
21009-409: Was first established and adopted worldwide during World War II . Throughout history, many cities have participated in various cultural exchanges and similar activities that might resemble a sister-city or twin-city relationship, but the first officially documented case of such a relationship was a signed agreement between the leaders of the cities of Toledo, Ohio and Toledo, Spain in 1931. However,
21158-449: Was formalized in 1944 and, after the end of the war, similar links were established to foster friendship and understanding among former foes as an act of peace and reconciliation, with new twinnings between Coventry and German cities: Kiel as early as in 1947 and Dresden in 1956. In 1957, Coventry was officially twinned with Belgrade, even though the link actually dates back to 1953 when then Yugoslav Ambassador visited Coventry and offered

In 1921, it was planned to become a special administrative region ( 瓊崖特別行政區 ); in 1944, it became Hainan Special Administrative Region with 16 counties , including the South China Sea Islands . During the 1920s and 30s, Hainan was a hotbed of banditry, many opposition politicians were hanged, therefore opposition politicians went into hiding. The Communists and
21456-533: Was in 1947 between Worthington, Minnesota and Crailsheim . St Petersburg in Russia holds the record for the largest number of partnership arrangements with other communities.
