According to reports on April 19, US media reported that many Chinese airlines have suspended the receipt of Boeing aircraft and the purchase of related equipment and parts. The latest report mentioned that flight tracking data showed that the Boeing aircraft that had just arrived at a factory in China last month was returning to the United States on the 18th. This suggests that at least one Chinese airline has returned Boeing orders due to Trump's tariffs.

On the morning of the 18th, one of the planes took off from Zhoushan to Guam, which was one of the stops for such flights before crossing the Pacific and arriving in Seattle. This means that the Boeing aircraft is returning.
Earlier, the aviation industry media "The Air Current" magazine reported on the 17th that one of the four Boeing aircraft that had arrived at the Zhoushan factory had been marked with a label that "can be recalled to the United States without handover."
According to sources, China announced last week that it would impose 125% tariffs on U.S. goods. The tariffs alone will more than double the cost of U.S.-made aircraft and their parts, effectively preventing Chinese airlines from receiving Boeing aircraft.
I have to say that this blow is still very serious to Boeing...
