China is still missing the point. It fails completely to consider any non-authoritarian route. Whatever this treaty finally says, nations will have to agree to it. That means _compel_ their people to go along with it or be in breach of international law.
With The Middle Kingdom's current and past distaste for international law it is a long bow to pull in the first place. It is just to 'bind' other nations people. China will ignore it even if it wrote it.
