Hugo Chavez warns the Colombian government against allowing the US set up a military base on its joint borders with neighboring Venezuela.

The Venezuelan president said on Wednesday that he would consider such measure as an act of an "aggression", AP reported.

In the message, President Chavez has underlined that he would not let Colombia establish an American military base in La Guajira, northeastern Colombia and northwestern Venezuela.

Chavez said if Colombia allows the launch of the military base in that region, his government will revive a decades-old territorial conflict which might engulf the whole region.

"We will not allow the Colombian government to give La Guajira to the empire," Chavez said, referring to the US during a speech to a packed auditorium of uniformed soldiers. "Colombia is launching a threat of war at us."

US Ambassador William Brownfield had recently suggested that a US military base in Ecuador could be moved to La Guajira.
