evidence: Bhutan [edit]Bhutan has long had strong cultural, historical, religious and economic connections to Tibet. Bhutan's border with Tibet has never been officially recognized, much less demarcated. The Republic of China based in Taiwan officially maintains a territorial claim on parts of Bhutan to this day.[4] The territorial claim was maintained by the People's Republic of China after the Chinese Communist Party took control of mainland China in the Chinese Civil War.[4][5][6] [...] Mongolia [edit]The People's Republic of China established diplomatic relations with Mongolia on October 16, 1949, and both nations signed a border treaty in 1962.[50] With the Sino-Soviet split, Mongolia aligned itself with the Soviet Union and asked for the deployment of Soviet forces, leading to security concerns in China.[51] As a result, bilateral ties remained tense until 1984, when a high-level Chinese delegation visited Mongolia and both nations began to survey and demarcate their borders. Mongolian General Secretary Jambyn Batmönkh, during a meeting with President Kim Il sung while on a state visit to Pyongyang in November 1986 states that "renewing the development of Sino-Mongolian relations is important for our two countries’ people's common interest".[52] In 1986, a series of agreements to bolster trade and establish transport and air links was signed.[51]
