The latest Jamestown Foundation China Brief has some great articles from Willy Lam, Russell Hsiao, and PLA studies star Dennis Blasko (side note: his book The Chinese Army Today is probably one of the better single-volume reads on modern PLA).
The most interesting ones are by Blasko and Lam. First, Blasko shatters some myths about the China's amphibious abilities for cross-strait invasion. China's amphibious capabilities are not at the stage where they can credibly threaten a seaborne invasion and appear to be structured for different missions. Blasko's article is very technical and difficult to summarize, but he does a detailed analysis based on both open-source reporting as well as the latest DOD report on Chinese military structures.
Second, Lam reports on an emerging foreign policy split between China's "hawks and doves" over future strategy. Apparently China's civilian security establishment--such as civilian professors of international relations and defense analysis at military academies and civilian universities, are warning of overreach and urging Beijing to hew to core interests more narrowly. Meanwhile, the more hawkish military intellectuals see themselves under broad threat from the United States in the Pacific and urge a stronger stance to expand Chinese power.
Hsiao also has an interesting piece on the continuing expansion of PLA military satellites, devices that can be used to further targeting of units operating on China's periphery.
