A QUESTION mark was last night hanging over whether an agreement had been struck between China and Hong Kong on the construction of the Western Corridor link to the mainland. Shenzhen Communist Party Secretary Li Youwei said in Beijing yesterday that an accord had been reached between China and the Hong Kong Government to build a bridge linking Shenzhen and the Western Corridor in Yuen Long. He also said both sides would form a joint-venture company to construct the bridge. But Secretary for Transport Haider Barma denied that there was an agreement. Mr Barma, who is also a member of the Sino-HK Infrastructure Co-ordinating Committee, said the Government had no plans to link the Western Corridor Railway with China. The new railway would stop in Lok Ma Chau in Yuen Long, with both sides only discussing passenger transit at the border, he said. At a press session during the National People's Congress plenum, Mr Li said details of the rail link project had been agreed. The starting point of the 5.3-kilometre bridge is located at Dong Jiaotuo in Shekou, with the end in Hong Kong set at Tin Shui Wai. The bridge would cost about $2 billion, Mr Li said. A joint-venture company responsible for the design, construction and bidding of the rail link would be set up by both governments. But Mr Li gave no timetable for completion of the project.
