China refused U.S. Secretary of State Rex Tillerson's demands to cut off North Korea's oil supply in an attempt to discourage Kim Jong-un from pursuing nuclear weapons, Bloomberg reports. Yesterday, National Security Adviser H.R. McMaster said at a White House briefing yesterday that the U.S. is "out of time" with North Korea.

• China's U.S. ambassador, Cui Tiankai, said the U.S. "should be doing more, much more than now, so that there is real effective international cooperation on this issue."
• Tiankai also said China would implement the U.N. Security Council resolutions, but "no more, no less."
• This came hours after North Korea fired a missile over Japan.
• China is a primary oil exporter to North Korea, and Trump has expressed frustration with China for not being hard enough on them.
