Mainland travel operators have been asked to suspend tours to Hong Kong next month when President Jiang Zemin visits to attend a business forum. Some mainland travel agents said yesterday they had been notified by the public security authorities to suspend tours to the SAR for the purpose of sightseeing or visiting relatives from May 7 to 9 - a peak travel season that coincides with the Labour Day holiday starting on May 1. Mr Jiang will arrive in Hong Kong on May 8 to address the opening dinner of the international business forum held by Fortune magazine and leave the next day. A travel agent in Guangzhou said: 'President Jiang will be going to Hong Kong. There will be no tours during the three days. All tours will have to return to the mainland before May 6.' An employee from Huamin Tourism in Hong Kong, which helps to organise tours for mainlanders, said the firm had heard about the ban but had not received any written notification so far. A maximum of 2,000 mainlanders are allowed to tour Hong Kong every day, most of them coming from Guangdong. Similar restrictions have been imposed on mainland visitors to Hong Kong and Macau on previous trips by Mr Jiang. In 1997, the two-way permit quota for mainland tourists was cut by almost 14,000 in the month straddling the handover. All tours were cancelled between June 30 and July 2 that year. Restrictions were also imposed on mainlanders travelling to Hong Kong and Macau last December when Mr Jiang visited the enclave to celebrate the first anniversary of its handover. The director of the Information Centre of Human Rights and Democratic Movement in China, Frank Lu Siqing, said: 'It's a normal policy when state leaders are visiting Hong Kong and Macau. 'They're worried that mainlanders who have grievances may take the chance to petition Mr Jiang as it would be easier to approach him in Hong Kong than in Beijing.' Mr Lu said among the concerns would be local Falun Gong practitioners who were planning to present a petition asking Mr Jiang to stop suppressing their fellow members on the mainland. Mr Jiang is expected to stay at tycoon Li Ka-shing's Harbour Plaza Hotel in Hunghom, where he can be shielded from protesters as he can be ferried directly to the Convention and Exhibition Centre in Wan Chai where the forum will be held.
