I won’t be so optimistic, let’s just assume that Trump banned all western parts to COMAC today, what could be the reason? It won’t be that Mr trump wants to slow down Chinese airliners’ development, it would be events like Taiwan/Philippine etc, judging by how it’s going, I’d say very likely. Banning engines may very much do no good for the US, but it would certainly causing problems for the Chinese, sanction is a card he could use, not optimal, maybe useless, but it’s emotionally satisfying.
