BEIJING (Reuters) - China’s Foreign Ministry on Wednesday urged North Korea not to violate U.N. Security Council resolutions after the North said its newly developed intercontinental ballistic missile (ICBM) could carry a large nuclear warhead.

Ministry spokesman Geng Shuang, speaking at a daily news briefing, also reiterated a call for calm and restraint.
