I think it's safe to say that China is not the most comfortable market, but Covenant, a dark horror movie, as a cut-to-pieces version, still managed to make 45 million.
Let's say The Predator makes a meagre 20 million there, 25 - 30 % = 5 - 6 million... that would still make it one of the most important markets when it comes to foreign distribution, which for a Predator movie is an average of 3 - 4 million in the top markets like Germany, France, Brazil etc.
Still a good deal.
