look at the countries they plan to invade

The ones that have US bases?

Yeah that's how you deal with US bases when the US puts bases all around your country with the intent of using them to invade you.

their ever increasing territorial claims

They've only given up land territories, and in the case of the ocean, are expanding in response to countries hosting hostile military bases.

Before the 9 dash line, they had the 11 dash line, they gave 2 dashes to vietnam after it was made clear vietnam wasn't going to host a US military base.

Then they invaded them a few years later, but dogshit foreign policy resulting from the sino-soviet split is another discussion.
