China agreed Tuesday that North Korea must face «punitive actions» for testing a nuclear device, a stance that opened the door to some form of U.N. Security Council sanctions against Pyongyang but did little to clear up just how much punishment Beijing will allow its impoverished neighbor and ally to take, according to The Associated Press. Diplomats at the United Nations held early talks over a U.S.-sponsored draft resolution that would impose stringent economic sanctions on the North, and planned more in the afternoon. China indicated it would not allow all the measures that the United States, Japan and their allies seek.
