WASHINGTON — A senior Trump administration official warned Sunday that North Korea’s provocative behavior “can’t continue,” and said the U.S. is working with partners including China to develop a range of possible responses to future “destabilizing behavior.”

“It’s really the consensus with the president, our key allies in the regions — Japan and South Korea in particular, but also the Chinese leadership — that this problem is coming to a head,” White House national security adviser Lt. Gen. H.R. McMaster said on ABC News’s “This Week.”
