There are a few sites I use for China/HK and Macau and SEA.
I have some other sites for Malaysia/Singapore too and SEA, you going there?
1) miss148.com - I search for COF/CIM/Greek providers
2) 161sex.com - I search for almost the same thing
3) new141.com - This is a good site too for all around fun for the price
4) go141.com - The largest database and hottest/most expensive girls here
