Boeing faces increased investor concern over the impact of Donald Trump’s trade war, as two 737 Max jets intended for Chinese airlines were returned to the U.S., reflecting the vulnerability of the aerospace sector to tariffs.

As Boeing prepares to release its financial results, experts warn of the long-term risks from escalating tariffs, particularly regarding access to the crucial Chinese market, which could affect future aircraft sales.
