Public lands and culture of the ability to access wild places, whether for hunting, fishing, hiking, camping, and just generally an affordance of access to wilderness that is codified into the laws of the country. In Europe they have the concept of "Right to Roam" which is a powerful concept that I appreciate (and in ways is superior to our systems for just walking in the woods) but it is also fundamentally different than the almost legalistic systems we have in this country towards public lands.
My surface understanding of China is that there is no such broad remit given to the people of China and there aren't designated places where the people of China can just go and exist in wilderness. Such places might exist by convention but they don't have the sort of legal framework that we have in America to recreate in these places.
