hey I'm an asian guy and let's get honest - this comment will get some hate and downvotes - but the facts are that the Chinese have a bad reputation in non-Chinese countries. The Japanese, the Koreans, and apparently the Thai (from the video) just hate the overbearing impolite way they do things. When I was in Paris, a MOB of Chinese tourists accosted me to try to get me to purchase some luxury goods for them (they have some kind of customs limit or stores have a purchase limit). It turned an otherwise uppity store like Louis Vuitton's flagship Paris boutique into what looked like a damn Black Friday Walmart opening.
The Chinese have a very adversarial way of doing things - no queueing up and cooperating for social efficiency. It's like a fire in a theater all the time. They'll knock your ass down and your 1-yr old off a bridge to save a buck.
