(CNN) -- Venezuelan President Hugo Chavez ordered his ambassador Saturday to go back to Colombia amid tense diplomatic relations between the two countries.
"Go back to Bogota, Gustavo. Go back to work," Chavez said to Ambassador Gustavo Marquez on state television.
Disagreements between the two countries prompted Chavez to recall Venezuela's ambassador to Colombia, as well as most of the embassy's staff in July.
The return of the ambassador comes at a time when Colombia has accused Venezuela of supplying Colombian guerrillas with weapons. Chavez has denied the allegations.
Relations between the two countries have also been tense over negotiations that could lead to American military bases in Colombia.
