Boeing’s stock climbed Tuesday after the American aerospace giant announced a significant jetliner order from Uzbekistan and as optimism builds around a potentially larger aircraft sale to China.

David Perdue, the U.S. ambassador to China, said he thinks negotiations over a possible deal involving Boeing and China are likely in their “final” days or weeks.

“This is a huge order, and it’s very important to the president, very important to Boeing,” Perdue said Tuesday while visiting China with a group of U.S. lawmakers. The ambassador did not give details on the pending transaction.

Perdue’s comments came a day after Boeing said that Uzbekistan Airways would buy up to 22 of its 787 Dreamliners. The Central Asian nation’s flag carrier plans to acquire 14 of the widebody passenger planes and reserved options for adding eight more to the order, Boeing said.

Boeing said the purchase would help the airline expand its international routes, including to the United States, while also “supporting nearly 35,000 U.S. jobs.”

Boeing’s stock price closed 2% higher on Tuesday, bringing its gain for the year so far to 22.2%.

President Donald Trump, in a social media post Monday evening, valued the Uzbekistan Airways deal at over $8 billion but erroneously said the order was for 22,787 planes.

Boeing declined to comment on Trump’s Truth Social post and referred questions to the White House. The White House did not respond to emails from The Associated Press seeking to clarify the numbers that the president cited.
