No American films get released in China over the summer due to rules to protect the Chinese film industry, so all "foreign" releases from the summer are delayed there. If Ant-Man and Dr. Strange can make $100M in China (they did), Spider-Man easily should as well.
However, Ant-Man is a promising statistic (it was at the time Marvel's 2nd largest opening in China next to Age of Ultron) but with predicting box office I'd rather aim modestly and leave room to be surprised. It'll be interesting to see where it ends up.
