I set up a credit card in Hong Kong, and I overdrawn by hundreds of thousands. If I don't pay it back, will the banks in Hong Kong arrest me?
Yes, this is an economic crime. If the amount is not particularly large, it's nothing. I can't go to Hong Kong at most. However, if hundreds of thousands of such banks report cases, there is no national border. Economic crimes are common all over the world, not to mention Hongkong or China. Even if you owe hundreds of thousands in the United States, you will be caught in China.
