Top U.S. aircraft manufacturer Boeing Company on Friday delivered its 2,000th airplane to China, which is a milestone for the U.S. aircraft maker in the world’s largest commercial aviation market.

The aircraft, a Boeing 737 MAX, is the eighth of the same model that Boeing has delivered to Xiamen Airlines, a fast growing carrier that operates the largest all-Boeing fleet in China with more than 200 jets.

“Our long-standing industrial relationship in this market has been mutually beneficial, fueling significant growth in Boeing’s business, the U.S. economy, and the Chinese aviation industry,” said Ihssane Mounir, senior vice president of Commercial Sales and Marketing at Boeing.

Che Shanglun, chairman of Xiamen Airlines, said his company has steadily grown in the past 34 years, doubling its fleet size over the past five years and achieving profits for 31 years in a row.

“Throughout that time, Boeing has been a valued partner in our growth and expansion by providing safe and reliable airplanes,” he said.
