President Xi Jinping vowed on Tuesday to show "zero tolerance" toward election fraud.

He made the remark when he joined a panel discussion of lawmakers from Hunan province, where a high profile vote-rigging case was reported in 2013.

That year in Hengyang, the second-largest city in the province, 56 provincial legislators were found to have offered 110 million yuan ($16.9 million) in bribes to hundreds of city lawmakers and election staff members to get elected.
