When I was at Polar we had the same problem with China Airlines... After the report the only Chinese airline allowed for DHDs was Cathay. I would suggest you push for the same.
Heck even Korean was off the list.

Of course, one of the last accidents in China was an iced up CRJ.

And dont forget that there have been a lot more accidents in china than make the press, even fatal ones.

Cathay maybe based in HKG, but it's as Chinese as a Taco. Swire still manages the place for now.

I would agree.
During our outside company safet audit 2 years ago (LOSA), the rep told me that Cathay was the most standard as they'd reviewed.
