BEIJING, March 28 (Xinhua) -- A senior official has called for more to be done to maintain social stability and security in China's border areas.

State Councilor and Minister of Public Security Guo Shengkun made the remarks during his visit to Guangxi Zhuang Autonomous Region, south China, from March 24 to 27.

All border area precautionary systems should be reviewed and improved, he said, adding that technology and data could enhance border area law enforcement.

The police should work with the public, who could help to maintain "a fortress of iron and a wall of bronze" in China's border areas, said Guo.
