If you have a satellite tuner that isn't limited to Freesat, there are lots of free Asian TV channels available.
My VT65 has an "other sat. tuning" menu. This tunes to every free satellite channel available via the Astra and Eutelsat (Eurobird) systems. You end up with almost 400 channels after tuning, the great majority of which are duplicates. I can't state precisely how many Asian channels there. The short answer is lots...
