Chen Shuang, whose hometown is Guangzhou, is a television producer in Beijing. When she visited her parents earlier this month, she first flew to Hong Kong for a quick stopover to buy presents and, in just three hours, spent a small fortune. Looking to corner a sizable chunk of the market created by the likes of Chen, China Telecom Corp has launched a one-stop portal, 'Best in' ( www.114.com.hk ), where visitors can book hotels, highlight the best dishes of a restaurant and find out more about the fun spots in places like Tsuen Wan that are usually not frequented by mainland tourists. An estimated 150 million frequent visitors from the mainland will come to Hong Kong in the next five years, spending HK$200 billion on accommodation, entertainment and shopping. The number of non-tour-group tourists from the mainland has been increasing 16 per cent annually since they were allowed to travel to Hong Kong as individuals in 2003. Last year, mainland visitors totalled 17.96 million, of whom 10.59 million were individual travellers, spending HK$20 billion among them. Mainland tourists who spent a night in Hong Kong last year on average spent HK$6,620, statistics from the Hong Kong Tourism Board shows. For those whose stay was even shorter without spending a night here, the average figure was HK$2,352. China Telecom's portal will also serve as a gateway for Hong Kong businesses to reach mainland consumers who cannot travel to Hong Kong. Currently, only 53 cities among the 660 on the mainland are covered by the individual travel scheme. The number of frequent individual travellers last year exceeded 10 million, representing just about one-60th of the mainland's 600 million urban population. For businesses that want to reach out to this huge market, China Telecom charges HK$1,000 per month as a registration fee. Those that want more than just to be found on the portal and are seeking to actually buy and sell through it are required to pay HK$1,500 per month. Deng Xiaofeng, chairman and chief executive of China Telecom (Hong Kong) International, said: 'The portal will help Hong Kong businesses tap into the enormous mainland market.' Online business-to-customer and customer-to-customer deals on the mainland have been growing rapidly in recent years, reaching 263 billion yuan (HK$300.92 billion) last year, up 108 per cent from the year before.
