Can I get back the fraud money when I go to Thailand?

In the case of a criminal suspect absconding abroad, it depends on whether the country where the criminal suspect absconded has signed an extradition treaty with China. If there is an extradition treaty, the public security organ may make an extradition request to a legal institution abroad through diplomatic channels to recover the fugitive. Thailand and China signed an extradition treaty. According to the provisions of the treaty, the two countries can extradite criminal suspects or criminals according to law, which provides a legal basis and guarantee for the cooperation between the two sides in combating crime.

According to the practice of international law, it is impossible to arrest people directly without judicial cooperation with other countries. But if it is a big case, you can arrest people through Interpol.
