During their talks over the past two days, Xi and Trump exchanged views on key areas of bilateral cooperation as well as global and regional issues of common concern.
Xi said his first meeting with Trump bears unique significance to the development of China-U.S. ties.
He added that he and Trump, during the meeting, have also gained better understanding of each other, cemented their mutual trust, scored many major consensuses, and built up a good working relationship.
The two sides need to further enhance their relations so as to better serve the interests of the two countries and their peoples, and to promote world peace and prosperity, Xi said.
China and the United States are now each other's biggest trading partner, from which the two peoples benefit a lot, said Xi.
Xi said China is pushing forward the supply-side structural reform, boosting domestic demand and increasing the share of the services industry in its national economy.
Xi also underlined the importance of further enhancing law enforcement cooperation and people-to-people exchanges.
"I think we have made tremendous progress in our relationship with China," the White House cited Trump as saying after meeting with Xi, adding that the relationship developed by Xi and himself is "outstanding."
U.S. representatives have been meeting one-on-one with their Chinese counterparts, and progress has been made, said the U.S. president.
Trump said the United States is willing to further strengthen cooperation with China in economy, military affairs and people-to-people exchanges, and support China's efforts in hunting for fugitives who have fled abroad and recovering illicit money.
Ahead of the two presidents' second round of talks, senior Chinese and U.S. officials on Friday initiated the comprehensive economic dialogue and the diplomatic and security dialogue, two of the four pillars of the newly established bilateral dialogue mechanisms.
