Bolivia, US patch up ties, ambassadors to return

LA PAZ - Bolivia and the United States agreed on Monday to patch up their differences and restore full diplomatic relations three years after the Andean nation's leftist president threw out the American ambassador.
In an agreement signed in Washington, the two countries pledged to work together to fight illegal drug production and trafficking. Bolivia is a major cocaine producer.
President Evo Morales, a former coca farmer and critic of Washington's policies in Latin America, expelled the US ambassador and Drug Enforcement Administration (DEA) agents in 2008, accusing them of plotting with his rightist enemies.
Washington responded by sending Bolivia's ambassador home.
Relations have gradually improved since then and talks to normalize relations started last year.
