In case of war, China's control of the South China Sea will be contested.
Australia will go ahead with planned Talisman Sabre large-scale exercises with U.S. forces:
The United States and Australia will hold a large-scale, multinational military exercise Down Under this summer despite the challenges of the coronavirus pandemic, according to the Australian Defense Department.
Dates and locations for the next installment of the biennial Talisman Sabre, which involved 34,000 U.S. and Australian personnel in 2019, have been posted on the Australian Department of Defence website. The drills, which take place mostly in the northeast state of Queensland, will kick off in late June and peak July 18-31, according to the agency.
Japan may also participate. It sounds like amphibious operations are a big part of them.
Hey, those Chinese-built islands in the South China Sea won't scrape themselves clean, you know. And China isn't even trying to improve relations with Australia.
As I've noted, claiming the South China Sea and holding the sea are two different things. With related U.S.-Australian cooperation information.
