A state-owned enterprise that had two of its former top officials implicated in a $30 million corruption case said yesterday it was conducting a clean-out to remove any illegal practices. The statement by China Travel (Holdings) Hong Kong Ltd, which has more than 3,000 employees, came as the Independent Commission Against Corruption (ICAC) sought legal advice and considered issuing a warrant to arrest the pair, who are now back on the mainland. Former group chairman Zhu Yuening, 57, and Xu Shiquan, 55, its ex-deputy general manager, are facing a probe into another mainland graft case. A spokeswoman for China Travel said the alleged offences had damaged the interests of China and of the enterprise and the group was determined to wipe out all illegal practices. The ICAC arrested two directors of a Hong Kong finance company for allegedly bribing Zhu and Xu to secure $30 million compensation for a collapsed deal to sell part of China Travel's stake in Chinese Mercantile Bank on the mainland for $160 million in April 1999. The compensation, which was 10 times more than the amount of $2.56 million due, was based on a dubious agreement between the two companies with altered clauses. Cash totalling $9.8 million and US$879,000 (HK$6.83 million) and a large quantity of valuables were seized, some from Xu's home and the rest in suitcases held by a third party. A third man - an employee of a trading company - was also arrested for his alleged role in handling illegal proceeds. Those arrested were released on bail. Zhu, who joined China Travel in 1995, was demoted to vice-chairman last April when Che Shujian replaced him as chairman. Zhu was later transferred to the mainland while Xu resigned last year. Transferring the suspects from China to Hong Kong could be difficult as the SAR Government is still working out a rendition agreement with the mainland. Democrat legislator James To Kun-sun last night called on Chief Executive Tung Chee-hwa to tell Beijing urgently of the difficulties encountered by the ICAC in bringing to justice senior staff of China-funded organisations involved in corruption cases.
