Hang Gliding in Vietnam?

I haven't been able to find any information about hang gliding in Vietnam, although paragliding seems to exist in some of the tourist areas. Is it illegal or am I simply the only one stupid enough to try? I'm pretty sure I could get a kite made there.

There were some great spots all along the QL27C that looked like it would be possible to soar all the way to Nha Trang! Same thing up around Da Nang.

You coming back sometime?  Never have done it but always wanted to try.  Have done skydiving, owned a couple of small planes, done aerobatic flying and once flew a glider in Las Vegas which I really loved but never did hang gliding.
