Donald Trump will demand Chinese leader Xi keeps promise to put pressure on North Korea

Isolating further over its nuclear and ballistic missile tests is a key goal for on what will be his longest foreign trip to date. 

President Trump will call on President Xi to fully implement UN Security Council resolutions against Pyongyang and take other steps to pressure North Korea. 

, North Korea’s sole major ally, accounts for more than 90 percent of trade with the isolated country. 

China has said it will strictly enforce UN Security Council sanctions banning imports of coal, textiles and seafood, while cutting off oil shipments to the North. 

But a senior White House official who briefed reporters ahead of President Trump’s trip said China needs to do more to comply with two UN Security Council resolutions that were approved unanimously, including with China’s support. 

“We would like to see China follow through on those commitments. We would like to see China do things bilaterally as well that might even go beyond things that are mandated by those UN Security Council resolutions,” the official said. 

Though China has been angered by North Korea’s repeated nuclear and missile tests and demanded they stop, Beijing also sees the United States and South Korea sharing responsibility for rising tensions because of military drills they carry out in the region. 

South Korea, the United States and Japan started a two-day missile tracking drill today, South Korea’s military said in a statement, in preparation for any missile or nuclear threats from North Korea. 

The exercises will be held in waters off the coasts of South Korea and Japan, South Korea’s Joint Chiefs of Staff said, with four Aegis combat system-equipped ships from all three countries participating in the drill. 

China’s special envoy for the North Korea nuclear issue, Kong Xuanyou, met his US counterpart, Joseph Yun, in Beijing on Monday, China’s Foreign Ministry said, where they had a “deep exchange of views on the Korean peninsula issue”.

The ministry did not elaborate. 

President Trump, who has threatened to “totally destroy” North Korea, has frequently asked China to help rein in North Korean leader Kim Jong Un. 

But this strategy has so far failed to stop Pyongyang conducting nuclear bomb tests at an underground facility and firing ballistic missile tests into the Pacific Ocean over Japan. 

The threat from North Korea has grown to a “critical and imminent level” and the United States, Japan and South Korea must address the matter, Japanese Defence Minister Itsunori Onodera told his US and South Korean counterparts in talks on Monday. 

Onodera’s remarks underscored the deep concern in Tokyo about North Korean weapons tests as Pyongyang seeks to develop a nuclear-tipped missile capable of reaching the United States.
