Definitely add her. Nothing ventured, nothing gained, right?
I would add with a message along the lines of 'hey, I finally found you' or something like that. It's not great, but it will probably get her talking back - and then you can go in with the conversation topics about English tv shows. The best thing about that is, after a few months, the chances are she's now watched those shows and you can talk about them.
I find online game the easiest of all games to get results - just be really positive, use the wink face a lot, and be a little braver with taking it to sexual grounds. Thing I found with Asian girls though (I like them too

), is you never know where they're at in sexual maturity. But, if you're girls other here, and out in bars and clubs, then I suspect she probably knows what shes doing.
Good luck.
