The Diplomat is reporting that the Chinese People’s Liberation Army Navy (PLAN) has acknowledged that they have begun to operate in the US EEZ off Guam and Hawaii (and presumably other US territory in the Western Pacific). This is actually seen as a positive step in that, by taking this step, China is recognizing that US Navy operations inside the Chinese EEZ are not illegal.
Still this means Coast Guard assets may encounter PLAN units, and as yet there is no counterpart to the INSEA (Incidents at Sea) agreement we had with the Soviet Union to minimize the chances for a misunderstanding.
A more aggressive, adventuresome, and far reaching PLAN might also be seen as a reason to consider reanimating the ASW mission in the Coast Guard.
Maybe for the foreseeable future, I do think the USCG should have the ASW and maybe the ASUW capability on hand.
A different opinion on the significance of the Chinese snooping in the US EEZ.
