This Day, That Year

Item from April 11, 1986, in China Daily: China will continue to build up its seismic expertise, (relating to earthquakes) and import state-of-the-art equipment despite declining income as a result of the current world oil glut.

Seismic expertise is vital to China's future oil exploration program.

China bought seven OPSEIS systems (used to gather seismic data), and these have been used in various areas, including Jiangsu and Sichuan provinces and the Renqiu and Dagang oil fields.
