Prosecutors accuse Liu Tienan of abusing power and pocketing millions

China's anti-graft campaign in the energy and resource fields is to be enhanced, analysts said on Wednesday, as the trial of former senior energy official Liu Tienan began.

Liu, 60, is accused of taking bribes worth 35.5 million yuan ($5.8 million) from 2002 to 2012 when he was a department chief and later vice-minister of the National Development and Reform Commission.
