GYEONGJU, South Korea, Oct. 30 (UPI) -- U.S. President Donald Trump departed from South Korea on Thursday after a highly anticipated meeting with Chinese President Xi Jinping that lowered the temperature on a simmering trade war with agreements on rare earth minerals, fentanyl, soybeans and tariffs.

The two leaders met for the first time since 2019 at Gimhae Air Base in the southeastern city of Busan, shortly after Xi arrived in the country for a three-day state visit to attend the Asia-Pacific Economic Cooperation summit.

Speaking to reporters on his way back to Washington aboard Air Force One, Trump described the outlines of a trade deal that he said would be signed "pretty soon."

According to the president, China agreed to take steps to stop the flow of precursor chemicals used to make fentanyl into the United States. In response, Trump said he halved the 20% fentanyl-linked tariffs he had imposed earlier this year.

"Based on [Xi's] statements today, I reduced it by 10%. So, it's 10% instead of 20%, effective immediately," Trump said.
