They are scared. They know that the Thai health system would not even be able to cope with a moderate outbreak, let alone a large outbreak like in European Countries. Most western countries have used the lockdown to fortify their health systems for a potential second wave or large outbreak as we have been doing here. I haven't seen any news of that happening in Thailand and the Government has already stated i can not afford widespread testing. If Thailand was to get a large outbreak it would likely be a disaster.
