In Bali, Chinese tour operators package Chinese-owned hotels and Chinese-owned restaurants for Chinese citizens to enjoy. They make a mess of the beauty spots and don't spend any money on local businesses. The Balinese are furious but can't do anything about it.
In Thailand, the story is much the same. Chinese business profit, the local economy doesn't.
Learning Mandarin doesn't help - the Chinese tourists don't appear to want to have any contact with the locals.
Western tourists may be rude, ignorant, drunken and disrespectable, but they have always been a good source of income.
In Australia, there are Chinese mines entirely staffed with Chinese workers, flown there direct from China. The local population get zero economic benefit. The state governments get royalty payments for the mine (that every mining operation has to pay).
