The trouble with the Chinese investment is going to be exactly the same problem that has given us the "counterfeit spare parts problem".
That is the overwhelming temptation when seeing an item , for example what appears to be a simple washer, shaft or pin, that has a list price of $350.00, to make a copy for $2.00 and sell it as the genuine article.
Without being racist, that temptation has overwhelmed many Europeans who ought to have known better, but that same temptation applied in China will be simply, completely, irresistible.
In China there is no concept of loyalty to anyone outside ones own family, let alone the concept of responsibility to an unknown foreign customer - hence the putting of melamine in baby formula.
Once the Continental parts inventory is "polluted" by Chinese manufactured items, forget the engine.
