Which countries in Southeast Asia require travel insurance proof?

Question

I've heard that some countries may require some travel insurance proof when entering to the country.

Which countries require that and what kind of insurance?

Do they accept any standard travel insurance such as that included with some Credit Cards, VISAs or personal banking although there is no any proof or some more specific certificates or papers (e.g. for Malaria)?

Specifically I'm interested for Hong Kong, Vietnam, Singapore, Philippines, Malaysia and Thailand.

Similar question, but for Europe.

Answer 1

None. I have visited all those countries and I wasn't asked about insurance by any country (we have free medical care back in my home country but I think that's irrelevant).

A note about your credit card's insurance: if you plan to use it, just make sure you are eligible for it before leaving the country. In most cases, you have to buy the ticket using that particular card and/or have spent a minimum amount using that card. I tried to make a claim a few months back. It didn't really went good.

Answer 2

Thailand talked about having tourists provide proof of insurance upon arrival, as too many travelers have skipped out on hospital bills (scooter crashes, etc). They have also talked about implementing insurance coverage for travelers paid by a fee to be collected upon arrival. But none of these ideas have been implemented and likely won't be in the near future.

With the exception of the Philippines, none of the other countries have asked me for proof of insurance when visiting recently (haven't been to PI in recent years).
