Uh, what sort of conflict do you think China could provoke? I have a hard time seeing a free salmon treaty with China giving rise to more conflict than normal neighbor disputes.
If Norway started selling all its oil to China, then we'd have something. But the EU borders Norway, and China doesn't so there isn't much in favour of it. In addition, China doesn't border the EU, so I don't think it sees much value in a divided EU (as opposed to Russia). To them it is probably more interesting to distance the EU from the US.
