Hong Kong and Guangdong are to launch a monthly publication to provide an insight for small and medium-sized enterprises (SMEs) in Hong Kong doing business in the Pearl River Delta. The Trade Development Council has co-operated with the Department of Foreign Trade and Economic Co-operation in Guangdong for the first time to launch a monthly publication, Inside PRD. It aims to provide SMEs with practical information such as the law and logistics of doing business across the border. The council's deputy executive director, Anna Lai Wong Oi-ling, said overseas businessmen were also interested in entering the Delta market. 'SMEs in Hong Kong act as a middle party. I believe the message is very clear that Hong Kong and Guangdong have formed a strong partnership,' she said. Chen Qiu Yan, of the Department of Foreign Trade and Economic Co-operation in Guangdong, said: 'The Delta accounts for more than 90 per cent of Guangdong's total income. Of course there will be competition between Hong Kong and Guangdong, but we should focus on how to maximise our mutual benefits through more co-operation.' Asked to comment on a proposal to build a bridge connecting Hong Kong, Macau and Zhuhai, Mr Chan said such a project would require more infrastructure to be built in all three areas. According to research done by the council, there will be a 30 and 35 per cent increase in the logistics and air cargo industries respectively if the bridge is built.
