Half of them, 365 containers of jackfruit, dragon fruit and electronic parts, are at the Huu Nghi Border Gate in northern Lang Son Province, according to the Ministry of Industry and Trade.
Tan Thanh Border Gate in the same province reported there are 107 containers of mostly dragon fruit and watermelon.
Since unofficial trade has not resumed through Tan Thanh Border Gate, a large number of containers without contracts with Chinese importers have been blocked.
In northern Lao Cai Province, 200 containers are waiting to cross over.
The situation has persisted since the end of last month, and the ministry has urged traders to find other distribution channels for their fruits.
Last month Vietnam’s trade with China, the largest buyer of its fruits, plunged by 11.8 percent year-on-year.
