[Its All Over Except ...]

Ironic you said “This does not require comparison, relevance, or pertinence to any US policy here.” So....

If it does, establish your point better.

US policies, historical or otherwise, are not mentioned in the article or post. In particular, there is no mention that Chinese warship presence is hinged to or dependent on the "Monroe Doctrine"

So, therefore the burden is on you to establish that it is.
