I will be flying in Business Class on that flight, but my friend is in Economy. (We both used Delta miles, but he was cheap haha)
While I am not familiar with Skyteam lounge access rules: In the world of air travel, HKG-China is always an international flight. So if that's the only criteria, you will get in.
