I think the closest we would come to another Hai Nan incident would be a South China Sea FONOP disaster, either with official Chinese "civilians" or a legitimate PLAN-USN conflict where the former tries to push the boundary of the sphere of influence that they patrol and the latter refuses to change course citing that they are following normative procedures.

I guess its similar to how China recently spins that their patrols successfully "deterred" USN FONOP exercises from going somewhere they shouldn't, when in reality the FONOP just occurred in its usual fashion.
