"If China is not going to solve North Korea, we will".
Trump's deputy national security adviser, K.T. McFarland, said there was a "real possibility" North Korea could be capable of hitting the United States with a nuclear-armed missile by the end of Trump's four-year term, the Financial Times reported.
"We hope that the events will proceed calmly and with order considering the state of inter-Korean relations", she said.
It's impossible to tell if North Korea is putting on a performance for the satellites - a ploy it has sometimes used to raise tensions - or if a sixth nuclear test is imminent. "And if they do that will be very good for China, and if they don't it won't be good for anyone".
United Nations resolutions have failed so far to deter North Korea from conducting nuclear and missile tests.
The two are expected to discuss a number of issues, including North Korea, trade and territorial disputes in the South China Sea during their meeting on Thursday and Friday. Following that country's early March missile tests, which came provocatively close to Japan, the U.S. leader emphasized his administration's commitment to "deter and defend against North Korea's ballistic missiles using the full range of United States military capabilities".
The relationship between the United States and China has been uncertain since Trump's election. "We have those options", he said.
Two North Koreans based in China and one North Korean based in Cuba were blacklisted for ties to Korea Ryonbong General Corporation, a previously sanctioned company that "specializes in acquisition for North Korean defense industries and support to Pyongyang's military-related sales", the statement said.
If Washington sees changes it likes, it will remain a member and if not "we'll put out", she said. When pressed about whether he could do it one-on-one without China's help, the president said, "I don't have to say any more". A bipartisan bill sponsored on March 21 by lawmakers affiliated with the House Foreign Affairs Committee, the Korean Interdiction and Modernization of Sanctions Act allows for bans on the sale and transfer of crude oil and petroleum products to North Korea and on employment of North Korean workers at the executive branch's discretion.
