The United States and Venezuela are to reinstate ambassadors to each other's capitals following tit-for-tat expulsions last year.

Officials in Caracas and Washington confirmed the decision, which follows an easing of tension since President Barack Obama came to office.

President Hugo Chavez ordered out the US ambassador last September.

The move followed allegations that Washington was plotting a coup d'etat in Bolivia.

Venezuela's foreign minister Nicolas Maduro said that diplomatic movement would take place in the coming days, and as soon as the ambassadors have resumed their functions they will move forward to a more fluid communication.

"Both ambassadors will return immediately to their work - our ambassador, Bernardo Alvarez, in Washington, and US ambassador Patrick Duddy in Caracas. That is the plan," he said.

President Chavez said in April, at a summit of the Americas where he met President Obama for the first time, that he hoped to send an ambassador back to Washington.

Mr Chavez was a fierce critic of the US under former President George W Bush, accusing Washington of plotting to assassinate him.

Analysts say Mr Chavez has toned down his criticism of US foreign policy since Mr Obama took office in January.

In a sign of warming ties, Mr Obama shook hands with Mr Chavez at the summit, and accepted a book from the Venezuelan leader.
