I see it more as a political move on the part of China. It can also be argued however that Chinese assets in say Cambodia or Myanmar will better enable China to break out of the First Island Chain;' similar to the roles China's islands/reefs in the South China Sea play. As it stands however there is little possibility of China placing assets in Cambodia or Myanmar; even if it wanted to.I'm not sure prepositioning helps the Chinese a whole lot, arguably their best defended space is mainland China itself
Which is exactly what worries China. Assets in Australia better enable Chinese shipping in the Indian Ocean or the Melaka Straits to be interdicited. Those assets can also be deployed to Butterworth or Indonesia if the political situation permits.Australia gives another vector to project power.
I think they do but aren't sure yet [neither are the Americans for that matter] as to how far is the U.S. really willing to go for Taiwan.But do the Chinese believe the Americans will actually go to war with them, over Taiwan?
They were in New Guinea and the Solomans months after Pearl Harbour.The japanese took years to fight there way to our door step
They also need to keep.various South East Asian states neutral. This is just as important because having hostile assets in these countries makes it somewhat complicated for the Chinese.They want Japan and SK to be out of the fight, by threat of force, and honestly, they can probably do that?
