If I'm not wrong. The vast majority of "foreign" parts are actually joint ventures. I wonder what % of parts China will have the ability to physically continue producing (ignoring ip rights) if sanctions do occur.Indeed. I actually suspect the deliveries of the key subsystems, particularly engine, will be controlled and limited. That is, if they're allowed to continue to be delivered at all. To hedge and reduce the risk, CJ1000A needs to be ready asap. If and when CJ1000A is available, the supply of LEAP-1C will be more likely to continue.
