Oil reserve takes shape as tanks fill

The tanks at China's first strategic oil reserve base station have started filling, a National Development and Reform Commission (NDRC) official has said.

The filling of the tanks, in Ningbo, Zhejiang Province, represent the latest step in the country's gradual effort to secure a strategic oil reserve, said NDRC secretary-general Han Yongwen.

But the challenges represented by the country's massive size could make building up a reserve difficult.
