Friendship Pass

Friendship Pass (), also commonly known by its older name Ải Nam Quan (), is a pass near the China-Vietnam border, between China's Guangxi and Vietnam's Lạng Sơn Province. The pass itself lies just inside the Chinese side of the border.

Vietnamese National Route 1 starts at the border near this pass, which lies less than 5 km north of the town of Đồng Đăng in Lạng Sơn Province, ending in Năm Căn in Cà Mau Province. China National Highway 322 runs from here to Guangxi Province and Hunan Province. This is one of the busiest border trading points of Vietnam.

It was built in the early Ming dynasty with the name of "South Suppressing Pass" (). In 1953, its name was changed to "South Harmonious Pass" (). In 1965, its name was changed again to the current Friendship Pass, reflecting the close political, military, and economic ties between the People's Republic of China and North Vietnam during the then-ongoing Vietnam War.
