There is definitely GA in Hong Kong if you will be getting down there
at all. I was able to fly a 172 out of Shek Kong airfield earlier this
year on a trip over there. They have 152s, 172s, a 182, a Slignsby T67,
and several R-22 helicopters. There are no XC flights except for the
couple of times a year when they get cross border authorization with
China, but the club is very active in training (particularly in
helicopters).
