Boeing Co. is heading closer toward finalizing a deal with China to sell as many as 500 aircraft, according to people familiar with the matter, a transaction that would end a sales drought that stretches back to US President Donald Trump’s last visit in 2017.

Boeing might be close to selling a boatload of jets in China, a vital commercial aerospace market that hasn’t ordered planes from the company in a while. Thursday, Bloomberg reported that Boeing was close to an order for 500 jets.

Boeing is in talks with China over a possible order for up to 500 commercial aircraft in what would be a significant win for the US firm.
