National Ballet Of China

In 1971, under UN resolution 2758, the representatives of Chiang Kai-shek to the United Nations were expelled from the intergovernmental organization. With the expulsion of the representatives, and effectively the Republic of China, the representatives of the People's Republic of China were invited to assume China's seat on the UN Security Council, the UN General Assembly and other United Nations councils and agencies. Later attempts by the Republic of China to rejoin the UN have either been blocked by the People's Republic of China, which has veto power on the UN Security Council, or rejected by the United Nations Secretariat or a United Nations General Assembly committee responsible for the General Assembly's agenda.
Since the relocation of its capital to Taiwan, the Republic of China has not formally renounced its claim to authority over all of China, nor has it changed its official maps, which include the mainland and Mongolia. Following the introduction of full democracy, and the electoral victory of the DPP's Chen Shui-bian in the presidential elections, the ROC had adopted a policy of separating the state's identity from "China", while moving towards identifying the state as "Taiwan".
However, the ROC has not made any formal moves to change the name, flag, or national anthem of the state to reflect a Taiwanese identity due to the lack of consensus within Taiwan, pressure from the United States and the fear of invasion or military action from the People's Republic of China against the island. The Republic of China during the DPP years did not actively pursue its claims on mainland China or Mongolia. However, after having been elected as president, KMT's Ma Ying-jeou asserted that, constitutionally, mainland China is part of the Republic of China. The People's Republic of China claims to have succeeded the Republic of China as the sole legitimate governing authority of all of China, which, from the official viewpoint of the People's Republic of China, includes the island of Taiwan.
Over the last 50 years, both the Republic of China and the People's Republic of China have used diplomatic and economic means to compete for recognition in the international arena. Because most international, intergovernmental organizations observe the One-China policy of the People's Republic of China, the PRC has been able to pressure organizations, such as the World Health Organization and the International Olympic Committee, to refuse to officially recognize the Republic of China. Due to the One-China policy, states around the world are pressured to refuse, or to cut off diplomatic relations with the Republic of China. As a result, 23 U.N. member states currently maintain official diplomatic relations with the Republic of China, while the vast majority of U.N. member states maintain official diplomatic relations with the People's Republic of China.
