Perhaps that's true, but it's sort of orthogonal. boeing and airbus don't make engines either; afaik no major aircraft manufacturer does (pending the inevitable exception). Granted, I don't understand how China's aerospace industry works, if it's basically just a large industry-wide state conglomerate. But not having locally sourced engines does not really give any information about comac's potential competitiveness.
