Well, I assume Gilead is allowing Chinese companies to manufacturer authorized generics at a price in line with average wages. So people in China already have access.
The other concern emerging economies like China have is they are already developing their own brand name/patented drugs. If they don't respect the US/EU patents, they can't really complain when the US/EU doesn't respect theirs. The US market makes up almost 2/3 of the western drug market, so it would be a huge lose for China.
