OFFICIALS of the Zhangjiagang free trade zone development corporation will visit Hongkong this week to lure local investment in China's second largest free trade zone. Mr Hu Jianpeng, general manager of the corporation, said the purpose of the visit was mainly to educate Hongkong investors on the potential of the zone, given that its development was approved by the State Council only last October. Located in Jiangsu province just north of Shanghai, Zhangjiagang is the only free trade zone in China which offers both river and sea ports. It is also intended to tap the economic growth along the Yangtze River. ''Its strategic location explains why the State Council allowed the setting up of the Zhangjiagang zone, which is comparatively close to another major free trade zone in Shanghai's Pudong area,'' Mr Hu said. He expected Zhangjiagang would play a complementary role in transporting heavy freight from inland areas to the global market. In terms of goods handling capacity, Zhangjiagang should have greater growth potential as Shanghai was already saturated, he added. Mr Hu will talk to potential local investors, outlining projects available for investment. Unlike other mainland free trade or development zones which put great emphasis on property development, Mr Hu said Zhangjiagang would like, in its initial stages, to establish its infrastructure. Hongkong investment has been scant to date, but the Hongkong-based Inter-Asian Group and the Zhangjiagang development corporation have formed a joint venture to develop a one hectare site into an industrial, exhibition and international trade complex. In addition, two container ports will be developed in the area which makes the project's total investment US$115 million. Mr Hu said about 90 projects including Sino-foreign and locally-funded enterprises had been approved. The majority of them were trade related, and agreements signed totalled about $600 million, he added.
