Sadly China
Only go to China if you are willing to put a bit of effort into making friends. Respect is the culture all over Asia and the rewards are good.
I had a great time in China, Korea, Philippines but then I put some effort into the bonding and it turned out trumps.
there is no doubt that most Asian systems are poorly designed due to bureaucracy but a little patients and a stiff coffee will get you on the right track.
Many friends in China and they are happy, especially every month when they visit the bank manager for a glass of champagne!
Work schedules are tough and delays are long, but the bucks are adding up.
Good luck
