It's in China's best interests to have USN stretched across multiple theaters (three - SCS, the Eastern Med, Persian Gulf/Red Sea) for reasons that should be obvious. Counting the containers' points of origin would make one think China would like to see this wrapped up quickly, but they think on longer timelines than quarterly earnings reports.

"Europe" doesn't have a Navy capable of projecting enough force to deal with the problem.

And, lastly, the raison d'être for today's USN is securing the free flow of global trade. So, it's very much unsurprising that USA is jumping in here (that we do not get paid for doing this service is a different matter).
