I visited them last year
and discussed their pilot needs.
The operation in HK, is the front for a USA 135 operator.
They were not interested in me due to being close to 60, and did not believe that ICAO, and eventually the USA would accept 60+ crew.
I have no reason to think they are suspect, as the office and management staff that I met were very nice, but rater busy.
I wish you luck.
