The touristic reason for Chinese police active in Thailand is trivial compared to two other major considerations:
1. There is a *huge* amount of Chinese organised crime in Thailand .. this is far more worthy of Chinese authorities presence here, rather than a tourist driven publicity stunt.
2. There is *huge* concern in several western countries about semi-official and also unauthorised covert 'Chinese Police' stations used as bases to project state power and intimidate (or more) Chinese citizens resident in democratic countries.
Noting that there are already documented cases of Chinese nationals suspected of being kidnapped by Chinese authorities *in Thailand*, the argument for formally allowing their officials to operate in Thailand needs serious examination.
