The insurance demand smells fishy to me. The motive should be to get tourist, retirees, and expats to have sufficient insurance, so they do not become a liability for hospitals in Thailand. I have been admitted to hospitals four times in Thailand and my insurance has paid all expenses. When my heart stopped, I was brought to Bangkok hospital. My insurance cover it. if I had insurance in one of the Immigration recommended insurance companies, I would have had to pay it all due to a preexisting condition.
For example, Pacific Cross insurance does not even cover treatment at Bangkok hospital, Bumrungrad and some other private hospitals. The approved insurance options look like a scam to enrich insurance agents and “others”. Thailand will lose out in the international competition to attract retirees at the time the Thai economy need us the most.
Thailand should re-consider their insurance demands. I have an excellent Government insurance accepted by Bangkok Hospital and other private hospitals. Sadly, it is not accepted by Thai Immigration. They want us to buy a Thai insurance that for me is worthless since I have pre-existing condition. The insurance demand will discourage A-O visa applicants and Thailand will lose revenues on the profitable retirees. Covid-19 should prove it is a good idea to have more retirees and expats, because viruses come and go, while we do not abandon ship.
