It's available in six different languages (although the only Asian language is Japanese).
It is by far the most attractive site that we have found, as well as the site with the highest confirmed Asian user base, making it a good choice if you don't mind the cost.
However, there is one caveat: the site doesn't cater specifically to Asian singles (anyone can join Perfect Match).
It does, however, allow you to filter by race, so it's hard to beat it for the sheer number of users.
Another company that ties into a larger database (Successful Match), Asian Women Date (formerly Asian Chats) has a few unique features that few other Asian dating sites offer, such as greeting cards, news relevant to Asians, and several verification options to allow users to prove their income, age, education, and occupation.
