China is American proofing itself in the event that the USA bungs trade sanctions on China and enforces those sanctions via its navy.
Xi, IMO, has anticipated that as far back as 2013 by: -forming China's BRI to protect trade routes to and from China of which the artificial islands in the South China Sea is merely a part.
Just spend a few weeks studying the BRI, mate and you'll discover what China's objectives are . The Ukraine War has advanced them in that the world of trade is rapidly morphing into a "two world" system from the previous globalised one engineered and led by the USA.
Just look at the map of the BRI, mate and you'll get a fair idea of how the world of trade is likely to divide in two:
From a shipping point of view , in the event of US Trade Sanctions on China , the choke points are: -The Straits of Malacca -The Straits of Hormuz -The The entrance into the Red Sea at Djibouti -The Suez Canal
I'll leave it to you to do some reading and then let us know what the Chinese Strategies are to overcome these shipping choke points...eh?
Its as easy as peeing in bed to call the perceived enemy names but it requires some grey matter to work out what China is all about and how/where/when the US will intervene to stymie China's grand plans.
There's loads of authoritative publications on this topic so its a matter of taking the time to read rather than the juvenile "I hate China" shoot from the hip posts, IMO.
To compete favourably with China we first have to understand China let alone Aus!
