Excepting circumstances where China could be affecting regional shared resources (e.g. damming a river -> drought in neighboring country, for example) is this not just based on willing participation? I don't understand what exactly it is that is being 'allowed' that should be forbidden.. if China exports to foreign customers is it against moral sense to not allow in foreign business? Also, I know of a certain country that relies heavily on its ability to sanction countries from effective participation in the entire global market..
