China is committed to the construction of a cross-border economic zone with Vietnam, said Ma Biao, chairman of southwestern China’s Guangxi Zhuang Autonomous Region. China and Vietnam decided in 2007 to each allocate 8.5 square kilometers of land from China’s border city of Pingxiang in Guangxi and Vietnam’s border town of Dong Dang in Lang Son province to build a cross-border economic zone. China finished the feasibility study on the Chinese side of the economic zone in 2009. Ma proposed that China and Vietnam grant more preferential policies in the Pingxiang-Dong Dang cross-border economic zone and build it into a regional import-export processing center, an international trade base and an international logistics center.
