BEIJING (AP) - The U.S. has called for other permanent members of the United Nations Security Council to adhere to the Nuclear Non-Proliferation Treaty.
The call Thursday by Undersecretary of State for Arms Control and International Security Affairs Andrea Thompson in Beijing comes as the U.S. is preparing to withdraw from a separate pact, the 1987 Intermediate-Range Nuclear Forces Treaty between the United States and the former Soviet Union.
Thompson says some countries are violating non-proliferation and developing new weapons programs, a likely reference to Russia, Iran and possibly North Korea. The NPT aims to stop the spread of nuclear weapons.
