Vietnam has banned trucks from China illegally carrying building materials from entering through northern border Ha Giang province, according to the Vietnam Road Administration.

Recently, 14 trucks with Chinese number plates were reported to be transporting quicklime, hydro-power parts and coke coal.

The trucks are not covered by road transport agreements signed between Vietnam and China .

Under a circular issued by the Ministry of Transport in 2012, there are two freight routes from China to Vietnam through Thanh Thuy-Tianbao border gate. However, they have not been officially opened.-VNA
