Trump says China working on NKorea 'problem'

McMaster was speaking hours after USA and South Korean defense officials told CNN that an attempted missile launch by North Korea failed. The good thing for the world is that the test turned out to be a dud for North Korea, as they attempted to get it going on Sunday morning and were not able to get it off the ground.

A North Korean missile "blew up nearly immediately" on its test launch on Sunday, the U.S. Pacific Command said, hours before Vice President Mike Pence was due in South Korea for talks on the North's increasingly defiant arms program.

The North Korean government flaunts an increasingly sophisticated arsenal of intercontinental missiles and launches a midrange version, which apparently fails seconds after takeoff.

As global tension heightened over the country's nuclear weapons programme in the face of fierce American criticism of the Pyongyang regime, Johnson said earlier the situation needed to be looked at carefully.

Kim Jong-un retorted that North Korean missiles will rain on American soil if Trump ordered an attack on North Korea.

However, no details about the telephone conversation between Chinese State Councillor Yang and Tillerson were released to the media.

The Trump administration has not indicated publicly it is interested in reviving moribund diplomatic negotiations with North Korea over its nuclear and missile programs.

After a two-month policy review, officials settled on a policy dubbed "maximum pressure and engagement", U.S. officials said Friday.

According to the adviser, the US had good intelligence both before and after the launch. Pence's schedule was not expected to be altered, a senior White House officials said.

Military officials in South Korea said the test of an unidentified missile carried out on Sunday had failed. Under his watch, North Korea has aggressively pursued a goal of putting a nuclear warhead on an ICBM capable of reaching the US mainland. The country launched a long-range rocket and conducted the two nuclear tests past year, including its most powerful to date.

Deputy national adviser K.T. McFarland briefed the president on the failed missile launch.

The vice president was joined by his wife and two adult daughters and was laying a wreath at the Seoul National Cemetery at the start of his trip.

"Unfortunately the President's failure to name China a currency manipulator is symptomatic of a lack of real, tough action on trade against China", Senate minority leader Chuck Schumer said. "The president has no further comment".

The Trump administration has touted some successes on that front in the past week, including the suspension of coal shipments from North Korea to China.

"I have great confidence that China will properly deal with North Korea".

"We have a wide array of tools at disposal for the president should he choose to use them", the official said.

U.S. Vice President Mike Pence says the "era of strategic patience is over" with North Korea, expressing impatience with the unwillingness of the North Korean regime to move toward ridding itself of nuclear weapons and ballistic missiles.

North Korea's big day, the anniversary of the birth of its founding leader, Kim Il Sung, came and went with no underground nuclear test by the North, and no pre-emptive strikes off the deck of the USS Carl Vinson aircraft carrier sent to waters off the Korean Peninsula by President Donald Trump. The United States, South Korea and other countries have vowed to apply more pressure on the North, but so far nothing has worked to stop Pyongyang's nuclear program.

A crisis management center at the Japanese prime minister's office said later that it has reached the same conclusion as the United States that the DPRK launched a missile but it exploded.

The first test of this year - the successful test of a land-based KN-15 missile on February 12 - was considered "a major advancement" by North Korea. Because the use of the "Moab" in Afghanistan was also a reminder to Pyongyang that the United States does not need a nuclear strike to destroy the regime: it could simply decapitate the leadership in their bunkers.
