This is a little off-topic, but I have a friend who is flying an N-registered aircraft based out of China and he said that once he gets his Chinese CAAC license and they transfer the aircraft to a Chinese registry, it may be the only Chinese company he ever works for unless they go under or they are bought by another company. As he understands it, the CAAC's position is that the company owns the license/records and any prospective employer would have to buy-out his previous employer (in the neighborhood of $100,000) in order for the license to have any validity with a new employer.
