Isolating North Korea further is a key goal for Trump on what will be his longest foreign trip to date. His Nov. 3-14 trip will include visits to Japan, South Korea, China, Vietnam and the Philippines.
China, Pyongyang's sole major ally, 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. China accounts for more than 90 percent of trade with the isolated country.
But a senior White House official who briefed reporters ahead of the 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.
Trump is in a standoff with North Korea over its nuclear weapons ambitions and has threatened to "totally destroy" the country.
The failure to confront and reverse the nuclear and missile threat from North Korea will lead to a "much darker era," the White House official said, speaking on condition of anonymity. But the official also said Trump is looking for a peaceful resolution of the North Korea standoff.
With Xi consolidating power in the wake of a Communist Party congress in Beijing, Trump believes the Chinese president will have a greater authority to take steps against North Korea, senior administration officials said last week.
Trump will also be tough on trade during talks with Xi as he seeks to reduce the US trade deficit with China, the senior White House official said.
"We have huge barriers that Americans companies have to surmount to gain access to the Chinese market. The president is intent on rectifying that situation," the official said.
