High-tech lookout keeps eye on border

Many border areas in China have deployed an integrated frontier monitoring system consisting of advanced radars and unmanned aircraft, a designer of the system said.

"Our system has been adopted by border defense units in Xinjiang, Tibet, Yunnan and many other regions to curb illegal border crossings and drug trafficking," said Mao Weichen of the Southwestern Institute of Technology and Physics in Chengdu, Sichuan province. "Users also include some airports and military bases."

The institute is a subsidiary of China North Industries Group Corp, the country's major manufacturer of land weapons.
