China is to intensify its so-called Go West policy over the next five years, stepping up preferential investment policies, boosting governmental investment, and introducing more preferential tax rates to encourage further growth in the country's Western regions, a senior development official told the China Daily. Li Zibin from the Office of the Leading Group for Western Region Development at the State Council told the daily that more funds would be directed at building local infrastructure and improving the ecological environment. Exact financial details were not given in the report. "We need an additional five years to turn western China into an ideal zone for investors from home and abroad," Li was quoted as saying. China's Go West policy was launched exactly five year ago, designed to encourage investment in 12 provinces, autonomous regions and the Chongqing Municipality and help narrow the prosperity gap with the wealthier east coast.
