Kruger, there isn't a preferred nationality. They are taking from where ever they can get experience, it is just hard to attract experienced guys on the T&Cs on offer. They need to upgrade more guys than they have on the books now. Anyone with 4000+ hours, preferably a jet command, and one head is getting a look in. This is their priority currently to fill a hole caused by hiring all zero time pilots for years, 'suddenly' left with no one to upgrade.
Good luck, its not a bad stepping stone, they don't bond you, and you don't pay for the rating, just do your homework on Hong Kong. If breathing is something you consider to be a necessary part of your day to day routine, think carefully.
