China National Nuclear Corp will speed up overseas uranium mining exploration, focusing on Australia, Africa and Central Asia, to meet the energy company's growing demand for the raw material, its chairman said on Monday.

"We have no worries about uranium resource reserves, as we will enhance efforts on exploring the resources both at home and abroad," said Sun Qin, chairman of China National Nuclear Corp, a State-owned energy company which runs more than 40 percent of China's nuclear sites.

He said the eurozone debt crisis has given Chinese companies such as CNNC a good opportunity to expand their overseas mining operations.
