On the second point, I disagree.
IP is not some basic, natural law. It's a relatively recent invention, ostensibly invented to promote certain economic incentives. Why is china morally obligated to respect it?
At any given point in time, the biggest effect of an IP system is how it affects the current portfolio of patents & copyrights. That's what tends to dictate the rules. When copyright law is updated, it's the impact on Disney's IP asset portfolio that's considered... not future works that will be created. It's a similar dynamic for patents.
Why should china (or any country) have to subscribe to an IP system under which they don't own as many patents.
Meanwhile, the benefits of a patent system are contraversial, even dubious (imho). Lots of intelligent peoe think they do more harm than good. The billions spent by tech companies on patent lawyers are a case-in-poiny.
I do not think we (globally) are best served by a global IP monolith. This is one area where we can benefit from a diversity of rules.
