Nearly 100,000 vehicles were also cleared, and 1,236 tourist groups received at the port as well.
Tianbao, a land port in southwest China's Yunnan Province to Vietnam, cleared 841,000 people for entry and exit last year, official statistics showed.
The port is an important platform linking China-ASEAN Free Trade Area. The port administration said China-Vietnam border trade and tourism have gained momentum thanks to the Belt and Road Initiative and Tianbao's privileged location.
