Trump is expected to meet Chinese President Xi Jinping as part of the extended visit, as the two sides weigh whether to extend a trade truce that paused a tariffs escalation, said the official, who declined to be named while discussing details that have not been publicly announced.
"That's going to be a wild one," Trump told foreign leaders on Thursday about the China trip.
"We have to put on the biggest display you've ever had in the history of China."
The visit would be the leaders' first talks since February and their first in-person visit since an October meeting in South Korea, where Trump agreed to trim tariffs on China in exchange for Beijing cracking down on the illicit fentanyl trade, resuming U.S. soybean purchases and keeping rare earths exports flowing.
According to Trump, Xi also said during the February call that he would consider further increasing soybean purchases. Soybeans are key because struggling U.S. farmers are a major domestic political constituency for Trump, and China is the top consumer.
