although a bit late in addressing this, china's defense minister called for preparations to improve off shore security and bolster the navy in the event of a "people's war at sea," obviously referencing the ongoing debacle in the south china sea between china and every other country in the area.
in july, the philippines took beijing to court over the disputed islands and ultimately won UN favor in declaring that china had no business to continue bullying its neighbors. china defied that resolution and is continuing to not only bully its neighbors, but build more artificial islands.
the united states has been posturing in the sea to protect maritime law there, as well as the $5 trillion that moves through it annually and the ~100 billion barrels (chinese estimate) of oil and 700 trillion cubic feet of natural gas that lie between its boundaries. the united states has also started stationing additional troops in the philippines as well as constructing more bases.
china and russia are to hold military exercises this september, but not to flex against third party, they claim. I think it's fairly obvious who they're flexing against and why they're doing it, but for the chinese to shift away from the US and back to russia is nothing short of worrying.
china is determined to not be the one to initiate war. if the US wants to stop them from encroaching on the islands, they'll have to take the initiative. this will, in turn, fill the 1.3 billion chinese with a resolve that the US will not be able to quell without extreme sacrifice.
