As military enthusiasts, what we really want to know is the resolution of China's spy satellites. Since that information is classified, we have to look at China's civilian imaging satellites to determine the baseline for estimating China's military satellite capability.
It's common sense that spy satellites have superior capability in comparison to civilian satellites. By analogy, military GPS has vastly superior accuracy in comparison to civilian GPS.
Anyway, you should click on the newslink and watch the short video on China's ZY-1-02C satellite. For your convenience, I have screen-captured some of the images from China's satellite.

China's civilian ZY-1-02C satellite has 2.36 meter resolution. The ZY-1-03C satellite has 2.1 meter resolution. China will launch three more satellites with 1 meter resolution.

I think this is a picture of the Beijing International Airport. Clearly, China's ZY-1-02C satellite can easily distinguish between different types of aircraft.

The ZY-1-02C satellite resolution is sufficient to allow an observer to read the Chinese characters on a warehouse. The first character means "large." I don't remember the other characters anymore.

I think this is a picture from space of the Forbidden City in Beijing. Each building can be clearly seen. For military use, a Chinese spy satellite will be able to provide real-time observation for an airstrike.
"High resolution imagery released from China's ZY-1-02C, ZY-1-03C satellites
Beijing, China - Feb 29, 2012
The latest high-resolution images delivered by China's high-resolution remote sensing satellites ZY-1-02C and ZY-1-03C were released by China's Center for Resources Satellite Data and Application Wednesday.
The ZY-1-02C, launched on Dec 22 of last year, has become the first customized land resources satellite for Chinese clients, the center said.
Yu Wenyong, head of the China's Center for Resources Satellite Data and Application, said, “Engines of large aircraft at Beijing's Capital International Airport can be clearly seen from the images delivered from remote sensing satellite ZY-1-02C, as well as vehicles and trees on the road, and the texture of the Bird's Nest and Water Cube, and even steel beams of the Bird's Nest are clearly seen.”
“The highest resolution of remote sensing satellite ZY-1-02C is 2.36 meters,” he added.
With two high-resolution color cameras and one multi-spectral camera, the ZY-1-02C will provide clients with images for disaster relief services, agriculture development, environmental monitoring and other applications.
China's first high-resolution remote sensing satellite ZY-1-02C has carried out orbital tests, and images delivered from it reach international standards, China's Center for Resources Satellite Data and Application said Wednesday.
“As for the ZY-1-03C, the highest resolution is 2.1 meters. The resolution of our current satellites has reached the level of the same kind in France, Japan and India,” said Yu Wenyong.
According to Yu, the test of ZY-1-02C and ZY-1-03C has entered the final stage, and they are about to be used. China will launch three more land resources satellites, and the pixelation will reach 1 meter, which will offer important technical support to China’s land resources and stereo mapping figures."
