• China has 130 Boeing airplanes that are identified in the Boeing backlog. On last week’s earnings call, officials said China accounts for 10% of its backlog of 6,319 aircraft as of March 31. This means there are about 500 Chinese-destined aircraft in the “Unidentified” backlog.
• Reconfiguring airplanes would cost millions of dollars. Backlogs to order materials and complete the work could be as much as two years. Engineering that may be required and regulatory review also could take a year or two.

April 28, 2025, © Leeham News: China used to be Boeing’s most important single collective customer. By the end of 2016, this country’s airlines and lessors accounted for between 25% and 33% of Boeing’s annual deliveries, depending on the year.

Boeing was losing ground to Airbus there. The European rival aggressively sought to partner with China. In 2008, the company opened an A320 family final assembly line in Tianjin. This followed a long courtship in which Airbus boosted its supply chain and engineering in China. Airbus establishing an A330 finishing center in China in 2017.

In China, doing business there meant providing “benefit” to its new and growing industries. “Benefit” was a loosely defined term that generally meant transferring technology, helping create a supply chain and ordering parts and components made in China. For some, it meant providing kickbacks. (This is not suggesting Airbus engaged in kickbacks, but corruption is a matter of public record. Such was suggested to me when I was doing business in China between 1989 and 1993.)

It had been a long struggle. When Airbus was establishing its presence there selling airplanes, some officials said they didn’t need any air buses—passengers boarded by jet bridges. Over time, Airbus began to surpass Boeing’s orders in China and today is the leader.

Boeing recognized it needed to do more in China. It floated the idea of establishing a 737 final assembly line in China, but its touch-labor union, the IAM 751 exercised its veto contract clause to stop the idea. Instead, Boeing opened a 737 completion center in China in 2018.

Completion centers paint the airplanes and install the interiors. A few 737s were at Boeing’s completion center when President Trump started the tariff war with China; the airplanes returned to the United States.
