A pilot anti-graft pension fund offering rewards of up to 300,000 yuan to officials who shun corruption is expected to start next year in Zhejiang, one of the mainland's richest provinces, state media reports say. The scheme was scheduled to start in Xiacheng district in Hangzhou and Cixi city in Ningbo , the Xinhua-run Contemporary Gold newspaper said. Officials will be required to contribute to the fund, which will be complemented by government subsidies, depending on rank. Government officials with no record of corruption during their tenure would be eligible for a pension payment on retirement, adjusted according to their rank and years of service. Disciplinary penalties for corrupt behaviour would result in deductions from their pension fund. The report did not give details about how much it would cost to set up the fund or how many people were eligible to join. But Tang Yijun of the provincial Commission for Discipline Inspection said implementing the policy would impose a heavy financial burden on the government. But the scheme on its own was not enough to fight corruption, according to an expert from the province's Academy of Social Sciences. 'The anti-corruption pension fund cannot serve as the main method to curb cadres' corruption,' said Xu Jianfeng , deputy director of the academy's Economic Institute. Rooting out corruption was reliant on the development of anti-graft mechanisms and the legal system, he said.
