One of Thailand's big hoteliers told me recently that in the past three years he had seen a huge increase in guests from mainland China and Russia - from just 5 percent of occupancy in his prime luxury hotel in Phuket to 70 percent currently.

Facing spending cutbacks from his main European customer base, he was talking to me about how to attract more Chinese tourists to his existing properties or perhaps open a new property targeting Chinese specifically when he suddenly said, "I’m not sure I want to cater more to mainland Chinese at my current hotels."
