>>1881862Huh??? Literally 35% of the parts in the Boeing 787 are from Japanese suppliers, including these massive ones.

Investors were not too pleased with the years lond delays and COVID-19 was the final nail in the coffin for the project. They decided to cut their losses, that is all.
The newly designed Pratt and Whitney engine on the spacejet was also supposed to give them a first-movert advantage but because the Embraer E2 Jet ended up released before the Spacejet, Mitsubishi now had no real comparative advantage to the rest of the regional jet class.
