BEIJING (Reuters) - China's foreign ministry on Thursday called for all sides to remain calm and exercise restraint after the United States said it was ready to use force, if need be, to halt North Korea's nuclear missile program.


China fully implements United Nations sanctions on North Korea, ministry spokesman Geng Shuang told a daily news briefing.
