You can find EASA approved facilities in Asia depending on what type you fly.
I worked in 2 countries in SE Asia which gave me a Validation using my EASA ATPL and I had to keep the
rating for what I was flying current. A320 for me was through Greendot aviation and AATC in Bangkok.
As for not bothering to renew, I would recommend NOT letting it go for more than 3 years after the expiry
date of last check unless you dont think you will be needing it again.
