evidence: Territorial disputes of the People's Republic of China This article is about territorial disputes of the People's Republic of China (PRC). A territorial dispute is a disagreement over the possession or control of land between two or more political entities. Many of China's territorial disputes result from the historical consequences of colonialism in Asia and the lack of clear historical boundary demarcations. Many of these disputes are almost identical to those that the Republic of China (ROC) based in Taipei, also known as Taiwan, has with other countries. Therefore, many of the subsequent resolved disputes made by the PRC after 1949 with other governments may not be recognized by the ROC.[1] [...] The last unresolved territorial issue between the two countries was settled by the 2004 Complementary Agreement between the People's Republic of China and the Russian Federation on the Eastern Section of the China–Russia Boundary.[69] Pursuant to that agreement, Russia transferred to China a part of Abagaitu Islet, the entire Yinlong (Tarabarov) Island, about half of Bolshoy Ussuriysky Island, and some adjacent river islets. The transfer has been ratified by both the Chinese National People's Congress and the Russian State Duma in 2005, thus ending the decades-long border dispute. The official transfer ceremony was held on-site on October 14, 2008.[70] However, in China Standard Map Edition 2023, Bolshoy Ussuriysky Island has been speculated by some journalists to be asserted as Chinese territory by China.[71]
