Exports of frozen seafood and agricultural products through the Km3+4 pontoon bridge crossing in Mong Cai, a border city area in Vietnam's northeastern Quang Ninh city, exceeded $878 million in the first 10 months of 2026, underscoring the crossing's importance in trade between Vietnam and China.
Located along the Vietnam-China border, the Km3+4 crossing in Mong Cai 3 Ward serves as a key route for transporting agricultural and seafood products from Vietnam to the Chinese market. Mong Cai lies opposite Dongxing in China's Guangxi region, making the border area an important gateway for cross-border trade.
According to Mong Cai International Border Gate Customs, frozen seafood accounted for $580 million of the total export value, while agricultural products, including cashew nuts and various fruits, contributed approximately $298 million.
In order to keep goods moving smoothly across the border, customs authorities have stepped up administrative reforms and modernized clearance procedures.
All customs documents are received and processed electronically, allowing officials to handle applications more quickly while ensuring compliance with regulations.
Closer coordination between customs officers and other border authorities has also helped shorten clearance times and reduce costs for businesses.
Customs officials regularly monitor import and export activities, assess businesses' needs and provide timely guidance to resolve difficulties that could disrupt cross-border trade.
Faster clearance is particularly important for agricultural and seafood products, which require careful handling and timely transportation to maintain freshness and quality.
By reducing delays at the border, customs authorities aim to lower storage and handling costs, protect product quality and help exporters meet the requirements of the Chinese market.
Mong Cai International Border Gate Customs plans to continue simplifying administrative procedures, modernizing customs operations and strengthening coordination with other border agencies.
The measures aim to facilitate trade, reduce costs for businesses and support the movement of goods between Vietnam and China through the Mong Cai border area.
