Taiwanese President Ma Ying-jeou has demanded an all-out end to graft after the island was rated even more corrupt than the mainland. Mr Ma, who has long pledged clean government, said he was distressed to learn Taiwan ranked higher than the mainland in terms of perceived corruption in the latest survey by the Hong Kong-based Political and Economic Risk Consultancy. 'Taiwan's democratic achievements, which are the pride of ethnic Chinese society, have been disgraced by corruption. It is something we can never accept and I feel pained because of that,' he told a news conference in Taipei yesterday. He ordered authorities to get to the bottom of any graft practices regardless of rank or political affiliation. 'Authorities must produce a review report on major corruption cases and work out countermeasures within three months' to minimise graft, Mr Ma said. In the consultancy's survey of 14 Asian economies, Taiwan ranked eighth in perceived corruption, with the mainland ninth. Indonesia was No1 and Thailand second. Singapore was the least corrupt, with Hong Kong just above it. The results were based on a survey of 1,750 local and foreign executives in the region's economies. The consultancy said it had added Australia and the United States, with a separate listing for Chicago for comparison purposes. The consultancy said the level of corruption involving senior government officials on the mainland was improving. In Taiwan, a local court is hearing the multimillion-dollar corruption cases involving former president Chen Shui-bian and his wife, Wu Shu-chen. On Monday, a retired general was indicted on charges of bribery. Taiwanese media described the survey as a 'slap in the face' for Mr Ma, who made a crackdown on corruption a major plank in his presidential election campaign last year. Mr Ma said the former Chen government was to blame for the corruption, 'it is an unavoidable responsibility for the new government to eradicate graft'. He stressed clean politics was not a slogan, but a policy. The Justice Ministry said it was drafting a plan to further crack down on corruption and ensure clean government. In a previous interview with the South China Morning Post, Justice Minister Wang Ching-feng revealed that she was pushing for the formation of an agency similar to Hong Kong's Independent Commission Against Corruption.
