The judiciary has been mobilised to add teeth to the Communist Party's anti-gambling campaign and authorities have tightened border controls to stop cadres from betting outside the country. Supreme People's Court vice-president Jiang Xingchang was quoted by Xinhua as saying that courts should show no mercy in sentencing cadres caught breaking regulations on gambling. 'For cadres who have violated the law and gambled, [courts at all levels] should - in accordance with the law - hand out the toughest sentences,' Mr Jiang said. He identified organisers of gambling rackets as the worst offenders and said they deserved the toughest penalties possible. '[We should] hand out heavy sentences to those who run gambling rackets and online gambling, as well as those who organise betting on Mark Six lotteries, soccer and horses.' However, Xinhua also quoted judicial sources as saying judges should draw a distinction between gambling and 'normal, non-profit-making entertainment'. Mr Jiang's comments came as authorities reportedly tightened border controls in Yanji - a border city between China and North Korea - to prevent cadres from flocking across to a casino. The China News Service reported on its website on Friday that police in Yanbianzhou, which administers Yanji, now require cadres to submit approval from their superiors when applying for exit papers. The extra measure came after a report that Cai Haowen, former director of the traffic and transport management office in the Yanbian Korean Minorities Autonomous Prefecture, went on the run after he allegedly gambled away 3.5 million yuan of public funds in the casino in Rason. Soon after, the Yanbian Committee for Discipline Inspection ordered that any officials found gambling overseas would be dismissed from the party and their government posts. The CNS report said the authorities had not stopped local tour companies operating organised tours to Rason but had instructed them to follow the new travel requirements. Rason has become 'very popular with mainland tourists', according to media reports. Some mainland tourists spend an entire day in the casino. The anti-gambling campaign intensified after President Hu Jintao last Tuesday spoke about fighting corruption within the bureaucracy.
