"We agreed on many things, with others, even of high importance, being very close to resolved," Trump said in a social media post after the talks with Xi.
"I had a truly great meeting with President Xi of China."
Trump has returned to Washington after a week-long trip to Asia, which also included stops in Malaysia and Japan.
As part of the agreement, he said, China has committed to buying "a minimum of 25 million metric tons" of American soybeans each year for the next three years.
For the current season through January, Beijing agreed to buy 12 million metric tons of soybeans from the United States, according to Bessent.
Trump earlier said that China could begin purchasing "tremendous amounts of the soybeans" and other farm products "immediately."
U.S. Agriculture Secretary Brooke Rollins announced in a social media post on Oct. 29 that China had booked multiple shipments of U.S. soybeans.
"All of the rare earth has been settled, and that's for the world," he told reporters aboard Air Force One shortly after the talks with Xi.
Trump said Beijing had agreed to a one-year pause on its plan to impose stringent export controls on rare earths. He mentioned that the agreement could be extended after a year.
"There's no roadblock at all on rare earth. That will hopefully disappear from our vocabulary for a little while," he said.
According to the Chinese Commerce Ministry, Beijing will now suspend its countermeasures for a year, while the United States pauses related actions stemming from the Section 301 probes into China's maritime, logistics, and shipbuilding sectors.
U.S. Trade Representative Jamieson Greer, speaking to reporters on Air Force One, also mentioned this decision.
"We're going to postpone that while we negotiate with them about that issue," Greer said.
The president expressed confidence that Beijing would take "strong action" to stop the flow of precursor chemicals used in fentanyl production.
"I believe [Xi is] gonna work very hard to stop the death that's coming in," Trump told reporters while departing from South Korea.
In return, China will "correspondingly adjust its countermeasures" against the United States, the regime's commerce ministry said in a statement.
Xi will visit the United States "sometime after that," Trump said, saying the Chinese leader could be visiting either Palm Beach, Florida, or Washington.
Trump visited China during his first term in office in November 2017. Following the trip, companies from the two countries signed trade and investment deals worth more than $250 billion, although some had been in the works prior to the visit and many were nonbinding.
"It never came up. Taiwan never came up. It was not discussed, actually," he said.
Before the Trump-Xi meeting, Taiwanese Foreign Minister Lin Chia-lung said on Oct. 30 that Taiwan is "confident" in its relations with the United States and that the two sides have "close communication channels," dismissing speculation that Taiwan's interests might be compromised by discussions between the two world leaders.
Bessent, speaking in a later interview with Fox News, said the TikTok ownership transfer deal has received Beijing's approval and that he anticipated that the process could advance in the near future.
"In Kuala Lumpur, we finalized the TikTok agreement in terms of getting Chinese approval," he told Fox News.
"And I would expect that would go forward in the coming weeks and months, and we'll finally see a resolution to that."
"[China is] going to be talking to Nvidia and others about taking chips," Trump said, but the United States will be acting as a "sort of arbitrator or the referee."
Asked by a reporter whether his administration would authorize exports of Blackwell chips, Trump replied, "We're not talking about the Blackwell."
Trump said he would be speaking with Nvidia CEO Jensen Huang, who has been in South Korea participating in the APEC summit and meeting with global leaders and top Korean executives.
