When travel convenience is abused by visitors for tax-free trading, when the country's import tax revenue is compromised, and when household goods prices and cross-border tensions surge as a result of such activities, something is clearly amiss. These problems appear to be what the mainland and Hong Kong are suffering after multi-trip permits have been issued for residents in Shenzhen.
According to mainland authorities, only five in 100 mainland visitors from Shenzhen are "genuine" tourists, with the rest coming to stock up on goods for resale across the border without paying customs duty. The long queues of travellers with cartloads of goods at Sheung Shui train station every day shows how serious the problem is. Although both sides have vowed to step up enforcement, the situation is still far from satisfactory. The problems appear to have spilled to other stations recently. More needs to be done to address the problem.
It is regrettable that tempers flared again early this month after some mainland traders clashed with local activists in a rowdy protest outside Sheung Shui station. The authorities should step up enforcement. It is encouraging to hear that the issue has been put on the cross-border agenda. In a sign of closer co-operation, officials from the Customs, Bureau of Exit and Entry Administration explored tighter measures during a meeting with their local counterparts in late October.
The mainland side is reportedly considering limiting the number of times Shenzhen residents can cross the border in a day as part of the efforts to crack down on parallel imports. Hong Kong immigration officials have also pledged to turn away suspicious mainlanders who make several crossings a day. These are welcome steps to tackle the problem.
With tens of thousands of passengers streaming through the border each day, enforcement alone is probably insufficient to curb the abuse. It makes sense, therefore, for the authorities to tackle the problem at its root. Restricting same-day multiple crossings appears to be worthy of consideration.
The Security Bureau has understandably raised concerns over the impact on Hong Kong's image and the entry and exit policy. But the proposed measures are unlikely to affect genuine tourists. The authorities should carefully examine the implications and strike the right balance.
