My opinion is that you've misinterpreted and misstated. The way you've framed it, the question does not use the word "jurisdiction" in a consistent manner with its definition or practice and does not address operative elements of the international legal system. The framing of the question also is also not on topic: the question about the legal basis of the challenge (all the way at the top of the thread) is a general one, and your framing here hyperfocuses on non-operative concepts ("juristiction") and a single country ("China"). Not only have you framed the wrong question in my opinion, but the question is rhetorical, and then you also bother to provide an answer.

In summary I'd say your comment is not relevant to discussion about legal basis of the challenge. It contributes to a different topic not being discussed: "What is your personal feeling about China?" to which you've contributed a thinly veiled "Boo China."
