Considering CJ1000 was the product of a different international political climate, yes, political uncertainty will affect the product.Requiring licenses for engine intermediaries isn't an AECC specific sanction though if you deal with that political uncertainty anyway, would surprise me significantly if they weren't already working on replacing it
They ought to have initiated working parallel on a replacement. If they didn't, they would be now. Anyway, the reveal next year certainly wouldn't include these replacements. But it'll verify the engine core and other Chinese components.
