I agree that Thailand have few cases, which is similar in nearby Vietnam. I have interests in both countries - one where a family member is struggling to return and the other where a family member is, without a credible route home (that one is complicated, so won't elaborate).
The visa situations for both countries seem pretty complicated at the moment, and it would also appear to depend, in Thailand where the person intends to be, as well as the purpose of the trip) we have reluctantly shelved plans to visit this year, or in the early part of next, so have a UK winter in prospect, which we don't enjoy.
