Like everywhere else
In any country, including the USA they will hire captains with Type rating and loads of experience. But they will not hire foreigners without a type rating. Now if you are willing to spread and pay for a type rating a lot of companies will talk to you because now you are talking about saving a lot of money. China, India, Malaysia, Thailand, all Europe, USA, etc.
There is opportunities in China for Instructors but very few for anything else unless you are friends with who is hiring you. If anyone is interesting give me a PM a friend of mine is hiring instructors.
