Dongxing Port, Port of entry at China-Vietnam border, Guangxi Province, China

Dongxing Port is a land border crossing in Dongxing, Guangxi Zhuang Autonomous Region, China, facing Mong Cai in Vietnam's Quang Ninh Province across the Beilun River. It has two bridge crossings: the 111-metre Beilun River No. 1 Bridge, next to boundary marker No. 1369, for passengers and passenger vehicles, and the roughly 618-metre Beilun River No. 2 Bridge, opened in 2019, which also carries cross-border buses since November 2024.

The site emerged as a major trade route in the 20th century, connecting Chinese markets with Southeast Asian commerce through the strategic Guangxi corridor. It developed into a key crossing for bilateral goods movement between the two nations.

The crossing is named after Dongxing, a town long known as a "hundred-year trading port". The 111-metre bridge lane runs beside boundary marker No. 1369, and the marker gave its name to the "1369 Life Express", a green channel opened in 2016 that lets critically ill patients from both countries cross quickly to Dongxing People's Hospital. Since 23 March 2026 the first bridge lane is reserved for foreign travellers needing a visa and for Chinese and Vietnamese holders of specific documents, while the second bridge lane takes all valid travel documents.

Two crossings span the Beilun River: the 111-metre Bridge No. 1 beside boundary marker 1369, and the roughly 618-metre Bridge No. 2, opened in March 2019. Since 23 March 2026, Bridge No. 1 serves foreign travellers needing a visa issued on the spot and Chinese and Vietnamese holders of specific documents, while all holders of valid exit-entry documents may use Bridge No. 2. A cross-border bus linking Dongxing and Mong Cai via Bridge No. 2 began running on 29 November 2024.

The 111-metre bridge lane at the crossing runs beside boundary marker No. 1369, and the marker gave its name to the "1369 Life Express", a cross-border medical green channel opened in 2016 that lets critically ill patients from both countries pass quickly to Dongxing People's Hospital.
