Through such actions, China aims to dismantle the myth of U.S. “security guarantees” solidified by the military-backed U.S. dollar hegemony, dealing it a severe blow.

Now that's a task. Myth of US security guarantees is dismantled visibly ever since Vietnam and has been repeatedly dismantled again and again ever since, but there still are governments that believe it. Or are comprador enough to do it anyway (i strongly suspect it is the latter, no one can be this dumb).
