Treaty (NPT) in 1970, and Taiwan considers itself bound by both. Following UN General Assembly Resolution 2758 (1971) the United Nations recognizes the People's Republic of China and does not recognize Taiwan as a sovereign state with the legal ability to join international treaties. Because of its controversial political status, Taiwan has not been allowed to join either the Biological Weapons Convention or the Chemical Weapons Convention, but it has stated that it will abide by both treaties nevertheless. In addition, Taiwan has stated that it will continue to abide by the NPT, notwithstanding Resolution 2758. Taiwan was one of the original members of the NPT in 1968. After the People's Republic of China replaced Taiwan at the United Nations in 1971, in effect Taiwan ceased to be active as a participating party to the official NPT activities. However, it signed a trilateral agreement with the United States and the IAEA in 1971 stating that it would continue to abide by the terms of the NPT as a ratification party. While not a member of the IAEA, Taiwan does continue to subscribe to the IAEA safeguards under two agreements, INFCIRC/133 and INFCIRC/158.
