Chinese irredentism



Chinese irredentism involves irredentist claims to the territories of former Chinese dynasties made by the Republic of China (ROC) and subsequently the People's Republic of China (PRC).

Background
Under various dynasties or empires in the past, China acquired and lost territories that overlap with Burma, India, Korea, Mongolia, Russia, and Vietnam today. Some were tributary states.

Modern era
During the 20th century, the Republic of China claimed that numerous neighboring countries and regions used to be parts of China. According to Sun Yat-sen, the reasons for their loss were unequal treaties, forceful occupation and annexation, and foreign interference. Chiang Kai-shek and Mao Zedong were supportive of these claims.

In 1925, the Kuomintang issued a map that showed large areas outside China as belonging to China, including: large portions of Soviet central Asia, a portion of Ladakh, Nepal, Sikkim, Bhutan, Assam, Indochina, the Sulu Archipelago, Taiwan, the Ryukyus, the Philippines, Korea, and Sakhalin. A similar map was produced in 1954 by the Chinese Communist Party.

With the rise of Xi Jinping and increasing territorial conflicts, it is generally believed that China continues to adhere to irredentist claims. A 2023 map by PRC's Ministry of Natural Resources showed a ten-dash line in the South China Sea and depicted territories in dispute with India and Russia as Chinese. Although these claims were not new, a host of countries voiced their objections.

Bhutan
On June 29, 2017, Bhutan protested to China against the construction of a road in the disputed territory of Doklam. On the same day, the Bhutanese border was put on high alert and border security was tightened as a result of the growing tensions. In 2020, China claimed that the Sakteng Wildlife Sanctuary was also part of the territory in dispute.

East China Sea
The PRC has frequently deployed ships since the 2010s to contest Japanese claim over the Senkaku Islands.

India


China maintains territorial disputes with India with regard to Aksai Chin and the McMahon Line. The Chinese government claims the Aksai Chin as part of Xinjiang and Tibet, while the government of India claims the territory as part of Ladakh. The 1914 Simla Convention, which the Chinese government does not recognize, negotiated the McMahon Line between India and Tibet. Tensions between India and China have erupted several times, with the largest being the Sino-Indian War of 1962 in which China was victorious and gained control over Aksai Chin, and the 1967 conflict in which India won. The 2020 border clashes, which caused casualties for both sides, further strained Sino–Indian relations.

China has reinforced its claim by publishing maps depicting South Tibet as Chinese territory. China also pushed forward to reinforce its claim over Sikkim and Ladakh, and consolidating border control in Aksai Chin.

South China Sea


Territorial claims of the People's Republic of China (PRC) and the Republic of China (ROC) in the South China Sea overlap with the claims of Vietnam, the Philippines, Brunei and Malaysia. In 2020, the PRC announced the establishment of Sansha City, which included the entirety of the Paracel Islands and Spratly Islands.

Taiwan
The Republic of China (ROC) was established in mainland China in 1912 following the conclusion of the 1911 Revolution which led to the collapse of the Qing dynasty. The Chinese Civil War that broke out in 1927 was fought between the Kuomintang-led Nationalist government and the Chinese Communist Party (CCP).

Since the end of the Chinese Civil War in 1949, the de facto territories of the ROC are limited to the Taiwan Area which includes the island of Taiwan (ceded to the Empire of Japan in 1895 by the Qing dynasty of China; handover to the Republic of China in 1945) and several other islands. Meanwhile, the People's Republic of China (PRC), established in 1949 by the CCP, controls mainland China, Hong Kong and Macau. Officially, both the ROC and the PRC claim de jure sovereignty over all of China (including Taiwan), and regard the other government as being in rebellion.

Until 1971, the ROC was the representative of China at the United Nations (UN) and was a permanent member of the UN Security Council with veto power. In 1971, the PRC replaced the ROC as the representative of China at the UN.

Skepticism from Taiwanese toward the PRC has intensified as a result of growing Chinese nationalist threat to attack the island if an independent Taiwanese state was to be created. Since the election of the independence-leaning Tsai Ing-wen, the PRC has conducted numerous military drills preparing for possible armed conflict with the ROC.

Tibet
Tibet came under the control of the Qing dynasty of China in 1720 and remained under Qing suzerainty (or protectorate) until 1912. The succeeding Republic of China claimed inheritance of all territories held by the Qing dynasty, including Tibet. After the Xinhai Revolution in 1911, most of the area comprising the present-day Tibet Autonomous Region (TAR) became a de facto independent polity except for border regions such as Amdo and Eastern Kham.

After defeating the Kuomintang in the Chinese Civil War, the People's Republic of China (PRC) gained control of Tibet through a series of events that involved negotiations with the Government of Tibet, a military conflict in the Chamdo area of western Kham in October 1950, and the Seventeen Point Agreement, which was ratified by the 14th Dalai Lama in October 1951 but later repudiated.
