No I dont believe so, China I understand yes and just read the posts on SE Asia forum. I had to do the JCAB Initial (Japan) and that was also very involved.
When I worked in Malaysia my AME was also UK CAA approved AME and leaving UK revals out the MY C1 was pretty much the same
as UK so used to do both anyway at same time.
In Thailand I had license validation of MY FAA ATP so had to keep FAA 1st class med valid, again no prob as my FAA AME
was and still is in BKK, Thai DCA dont give ATPL to foreigners or at least didnt when I was there. As for other countries
I worked in 3 others in SE Asia using License Validation of my UK ATPL and that meant keeping my UK C1 valid.
Cant comment on Vietnam or Spore but feedback from friends in Country suggest no Arstronaut stuff.
Hope that helps your question, Regard's,
