(BJEV), a new energy vehicle producer, in Huanghua city of Cangzhou, north China's Hebei Province. Under a regional coordinated development plan, Cangzhou has benefited from the industries it took over from Beijing and Tianjin, two nearby metropolises. It has also done a good job in leveraging scientific and technological achievements. In the last five years, some 1,300 key projects in manufacturing, modern pharmacy, eco-technology and other fields have been introduced to Cangzhou with the total contracted investment volume reaching 602.7 billion yuan (about 87.4 billion U.S. dollars).
