Getting out of Thailand is possible, it is the getting back in that requires skills that even Houdini would find a challenge as the Thais keep moving the goal posts. Not sure what the thinking is you cannot be 100% Covid free, if you are what do you do,sit in blissful isolation ?
But a lot of the sound is in Chinese owned businesses and a lot off tour companies , coaches etc are Chinese owned You have seen the groups with Chinese guides taking them to select establishments mostly Chinese owned they like to spend their money with their own people.
If you thought Thailand was bureaucratic before you ain't seem nothing yet.This virus situation has given new lease of life to all the wanna be little Hitler's to make every body's life even more difficult.
