Hong Kong Airlines (HX) isn't a MileagePlus partner; therefore, no PQM (or redeemable miles, for that matter). Since HX isn't a member of an alliance, your credit options for that leg appear to be limited to their own program (Fortune Wings Club / shared with Hainan and a few other regional airlines) or Virgin Australia Velocity.
On a UA ticket, you can buy flights on any airline with whom UA has an interline agreement, but you'll only get mileage credit for MileagePlus partners.
