Which other countries in Asia are considered white?

There aren't really any. The biggest market is China. India could be considered part of Asia, and it's a huge market, but there are currently many clampdowns and arrests happening there. Japan is a very lucrative market with some form of regulation, but not the type that generates revenue for these operators. Known operators are present there. Then you have South Korea, Vietnam, Laos, Thailand, Cambodia, Malaysia, and others. These countries are not regulated.
