Furthermore the Western Pacific is getting more and more militarized every year, with various nations building up and modernizing their navies and the USN shifting their attention from the unimpressed European theater to the crucial WESTPAC. And especially with neighbors like Japan and the ROK, which field large fleets, it makes sense to just go "fuck it we ball". I can also imagine that the Chinese are very content with this development, as it would mean that in the future there would be aa sizeable, friendly Navy in the region which could distract and deal with lesser adversaries in a potential conflict against the United States (or alternatively also be used to harass USN ships).
