Vice President Mike Pence puts North Korea on notice, warning that recent U.S. strikes in Syria and Afghanistan showed that Trump's resolve should not be tested.
North Korea will continue to test missiles regularly and any military action against it by the United States will prompt "all-out war," a senior North Korean official tells the BBC.
China reiterates its opposition to the deployment of a sophisticated U.S. anti-missile system in South Korea.

North Korea did not respond this month to requests from senior Chinese diplomats, including the country's foreign minister, to meet North Korean counterparts, amid rising tension with the United States, Bloomberg reports.
