What, do you have some Asian fetish?  China, like most countries with a robust (or once robust) middle class has the problem of calorie convenience. People have access to loads of calories, in convenient processed foods, at low prices, that can be inhaled in seconds--and that, coupled with a lack of nutrition education, is leading to fatties all over the world. There have been papers written about China's ever increasing obese population for over a decade. They might be less polite about fatties in Asia, but it certainly isn't stopping mainland China from becoming just as fat as the west.
