U.S. says time to act on North Korea, China says not up to Beijing alone

U.S. Secretary of State Rex Tillerson warned on Friday that failure to curb North Korea’s nuclear and missile development could lead to ‘catastrophic consequences, while China and Russia cautioned Washington against threatening military force. Washington has recently lavished praise on Beijing for its efforts to rein in its ally Pyongyang, but Chinese Foreign Minister Wang Yi made clear to the U.N. Security Council it was not only up to China to solve the North Korean problem. “The key to solving the nuclear issue on the peninsula does not lie in the hands of the Chinese side”, Wang told the 15-member council in remarks contradicting the White House belief that it does wield significant influence.
