China has successfully put into orbit another remote-sensing satellite, “Yaogan IX” from the Jiuquan Satellite Launch Center in northwestern Gansu Province, according to a statement from the center last week. The satellite was sent into space aboard a Long March 4C carrier rocket and would be used to conduct scientific experiment, carry out surveys on land resources, forecast grain output and help with natural disaster-reduction and prevention endeavor, it said. Its predecessor, “Yaogan VIII,” was launched from Taiyuan Satellite Launch Center in northern Shanxi Province last December.
Yaogan IX is the newest member of a series of satellites believed to harbor optical and radar military reconnaissance capabilities. http://tiger-warrior.blogspot.com/ mentions:

The satellite „would be used to conduct scientific experiment[s], carry out surveys on land resources, forecast grain output and help with natural disaster-reduction and prevention endeavor[s],“ state media reports said.
But most experts believe the Yaogan series includes two variants with high-resolution electro-optical cameras and cloud-piercing radars designed to see targets through inclement weather or darkness.
