I don't know about training centres and generally speaking I should imagine you are right, but there's always the exception if they trust and know you. I am in Thailand. I am not a recruiter but recently I helped out an American. I found him a job in a Chinese university. Before the American had landed in China virtually the Chinese paid for the air fare from Bangkok, paid for a hard seat on a train, paid for the degree i had to purchase for him in Bangkok as the American was skint, and paid for my petrol expenses to drive the American from Lampang to Bangkok. I should say that I made no profit out of my good works. Personally have no need to work in China, I don't have to, but I have found the Chinese very reliable, if you give them cause to be.
