China seems like it's going to declare the whole China Sea its own , and block/police the South China Sea...currently international waters.
Australia atm has a military ranked about 17th in the world. Has recently just crept in front of Indonesia.
When...it all looks like going down in the South China Sea ...if all the countries in the region against its blocking sign on to the "Coalition of the Good" , and have decent weapons, plus Euros who trade with Australia etc, plus US...China might just think again.
