Wirestock/iStock Editorial via Getty Images China Development Bank’s financial leasing arm said it will buy 50 Boeing (NYSE:BA) 737 Max 8 jets, marking its second major aircraft order in a week. The order is a likely boost to the aircraft maker (BA), who is facing a downturn in Chinese orders and wrestling with union strikes and quality issues. The company expects to take delivery of the aircraft between 2028 and 2031, CDB Aviation said in a statement. China Development Bank Financial Leasing said the order will optimize its fleet structure and increase the proportion of next-generation aircraft with advanced technologies. Aircraft purchases by Chinese buyers have significantly slowed since 2018 due to strained U.S.-China relations, but slowly recovering.
