The United States is not close to an agreement with China on new United Nations Security Council measures to impose on North Korea over its fourth nuclear test earlier this month, U.S. Ambassador to the United Nations Samantha Power said.
North Korea said on Jan. 6 that it successfully tested a powerful nuclear bomb. Nuclear experts say North Korea likely gained data and practical know-how from the test. They reject North Korea's assertion that it detonated a hydrogen bomb.
The 15-member U.N. Security Council said at the time it would begin working immediately on significant new measures in response to North Korea, a threat diplomats said could mean an expansion of sanctions.
