The downfall of Bo Xilai has not slowed down the aggressive investment and rapid trade growth of Chongqing, the city he used to head. Bo was dismissed as Chongqing party chief in March and is currently under investigation for 'serious violations of discipline'. 'During the 12th five-year-plan period [from 2011 to 2015], our city will invest 20 billion yuan [HK$24.4 billion] to accelerate the development of Chongqing as an upstream shipping centre along the Yangtze River,' said Teng Hongwei, a senior Chongqing transport official, at a seminar on Tuesday. The city's goal of becoming a major shipping hub along the upper Yangtze River should be accomplished by 2015, Teng added. Last year, Chongqing's river trade reached 120 million tonnes, according to its government website. 'The Yangtze River will be a very important trade channel. With the shift of manufacturing to Western China from coastal regions, more goods will pass through the Yangtze to Shanghai, where they will be exported,' said Li Zhongjie, logistics director of Wuhan International Container Transshipment. In April, Chongqing's external trade skyrocketed 141 per cent to US$13.5 billion, with exports jumping 188.6 per cent to US$9.3 billion and imports soaring 77 per cent to US$4.2 billion, making it the Chinese city with the fastest growth in trade, according to the website. Nearly 40 per cent of exports last month came from notebook computers. In the first four months of this year, Chongqing's land-cargo traffic rose 74.5 per cent to 13,811 tonnes, while its air freight leaped 107.3 per cent to 29,809 tonnes. A lot of notebook computers, iPads and iPhones manufactured in Chongqing were exported by air, said Anthony Wong, past president of the Hong Kong Logistics Association. 'The economic figures for Chongqing are mind boggling,' Wong said. 'Chongqing enjoyed favourable policies under the central government while Bo was in charge of the city. Due to his previous tenure as commerce minister, he had lots of connections. He was able to attract a lot of new investment in Chongqing, from electronics companies and multinationals.' For example, in February, Bo received Terry Gou, chairman of Foxconn Technology Group, a leading manufacturer of Apple iPads and iPhones, and attended a ceremony where Chongqing mayor Huang Qifan and Gou signed a memorandum of understanding for the Taiwanese company to set up a research and development centre in the city. Taiwan's leading notebook makers Acer and Inventec have set up production bases in Chongqing, which can make more than 10 million notebook computers yearly, the China Post reported.
