The South American countries already reopened in September their border crossing in the Tachira state, in western Venezuela, after political ties strengthened under Colombia's new president, Gustavo Petro.

Petro and his Venezuelan counterpart, Nicolas Maduro, appointed ambassadors in Caracas and Bogota, respectively.

Colombian authorities have said since September that the reopening of the shared 2,200 kilometers (1,367 miles) border between the two countries would be progressive.

Last week, Venezuelan government officials were supervising the infrastructure of the Tienditas bridge.

"We completely reopen the border between our countries in order to guarantee the movement of cargo and passengers, and to promote trade and tourism in Colombia and Venezuela, not only by land but also by air and river", said Colombia's Minister of Transport Guillermo Reyes Gonzalez.

Elsewhere, people and cargo can already cross the border via two bridges in Tachira as well as the western Zulia state. Flights between the capitals Caracas and Bogota resumed in November.

The commercial exchange between the two countries is worth around $580 million, according to official data from Colombia.
