China returned a $55 million Boeing 737 MAX passenger plane due to the mutual tariffs between China and the United States (145% tariff from the U.S. to China, 125% tariff from China to the U.S.), resulting in a surge in costs. Boeing's stock price was affected, and China may suspend more orders, impacting its forecast of 9,000 new aircraft. The escalation of the trade war affects the global aviation industry, with several Boeing aircraft stranded in China and deliveries stalled.
