Guangxi Zhuang autonomous region in southern China will invest more than Rmb400bn on transportation infrastructure over the next five years, reported Xinhua. Ma Biao, chairman of the region, said priority would be given to developing a 1,700km transportation passage between southwest China and the South China Sea. That passage starts in Sichuan province and ends at the Beibu Bay in Guangxi, on the border of Vietnam. The regional government also plans to make Guangxi into a hub for transportation from China to countries in the Association of Southeast Asian Nations.
