JV Boob, several Chinese defense sites - sino defense, china-defense, Ministry of National Defense of the PRC, SinoDefenseForum - many other US Defense sites as well such as DoD Buzz, Foxtrot Alpha, Breaking Defense, Defense Tech, Defense News, Military News...
Just do a search for any of those, and you'll get a phone book of reasonably decent sites regarding Chinese/Pacific defense news.
If you want a look at Chinese Naval procurement, this is a good place to start as well -
http://www.jeffhead.com/redseadragon/plan-usn-comparison.htmYou can click through various years of Chinese Naval development, then through various comparisons with the USN based on types of ships, and so on.
IMO one thing of note from Jeff's page -
http://www.jeffhead.com/redseadragon/newfac.htm . This one little craft IMO shows how serious China is at pushing the USN and other allies OUT of the SCS. They have over 100 of them now, in a 7 year sprint China built 83 of these ships, while the USN finished but 2 LCS Frigates. The Type 022 is fast, very stealthy, and has 8 150km ranged extremely fast anti ship missiles. The math on that = the ability to flip hundreds upon hundreds of missiles at USN ships from stealthy fast platforms that are hard to detect and counter. And that's just ONE class of ship they've built recently, not counting their efforts in naval aviation, air independent subs, much improved nuclear subs, very solid Frigs and Destroyers, etc. They are currently building more Type 022s at a rate of several per month of that class alone. I bring this ship up specifically as all sources point to many of them being forward deployed at these new sandbar bases China is building.
We can joke about how unlikely confrontation will come, but China's buildup looks pretty serious IMO.
