Third Plenum decision to stimulate growth vitality, says senior adviser

China's economic vitality will be stimulated after the Third Plenum of the 18th Central Committee of the Communist Party of China, with the country expected to see a relatively high growth rate until 2020, a top policy adviser said on Friday.

The ambitious economic reform decisions mapped out by the new leadership will help China "maintain an average year-on-year GDP growth of about 8 percent" in the next seven years, said Zheng Xinli, executive deputy director of the China Center for International Economic Exchanges, a government think tank.
