The Colombia–Venezuela border is an international border of 2219 kilometers (1378 mi) between Colombia and Venezuela, with a total of 603 milestones that demarcate the line.[1] It is the longest border of both Colombia and Venezuela.
The border, at least in its terrestrial part, was essentially demarcated by two treaties: the Spanish Arbitration Award of Queen Maria Cristina of 1891 and the Treaty of Limits and River Navigation of 1941.[2] But the definition of the border in the Gulf of Venezuela is still disputed, causing diplomatic clashes between the two countries.
In August 2015, two Venezuelan soldiers were injured during a fight with alleged Colombian smugglers,[3] prompting Venezuelan President Nicolás Maduro to close a large part of the border, except in Táchira.[4]
