You can typically make over $200K USD flying a regional jet in China with some earning close to $300K with OT. You can make only a little more by flying larger equipment.
Heck even part time flying in China (six months off per year) you can make about $180,000.
The tax benefits of working in China mean that you would have to make a lot more than the above numbers to earn the same amount in another country.
Of course working in China will take years off your life expectancy so you have to consider if it's worth it. If you can get a heavy job for a Chinese carrier based in a western country that would be awesome...there are a few such jobs.
