WASHINGTON — Days before President Trump hosts his Chinese counterpart, Xi Jinping, a top U.S. official warned Tuesday that “the clock has run out” on decades of diplomatic efforts to rein in North Korea’s nuclear and missile programs, and military action may ultimately be necessary.

“The clock has now run out, and all options are on the table for us,” the official told reporters at a briefing held on condition that he not be identified by name.

Hours after those remarks were reported, North Korea fired a ballistic missile into the waters off its east coast, according to South Korean officials.
