U.S. Secretary of State John Kerry said on Thursday he made clear in a phone call with Chinese Foreign Minister Wang Yi that China's approach to North Korea had failed and it was time to end "business as usual" with Pyongyang after its nuclear test.

"China had a particular approach that it wanted to make, that we agreed and respected to give them space to implement that," Kerry told reporters. "Today in my conversation with the Chinese I made it very clear that has not worked and we cannot continue business as usual."
