Though Chávez inspired other movements in Latin America to follow his model of "chavismo" in an attempt to reshape South America, it was later seen as being erratic and his influence internationally became exaggerated. He refocused Venezuelan foreign policy on Latin American economic and social integration by enacting bilateral trade and reciprocal aid agreements, including his so-called "oil diplomacy" making Venezuela more dependent on using oil, its main commodity, and increasing its longterm vulnerability. Chávez also aligned himself with authoritarian nations and radical movements that were seen as being anti-Western, with relations with Cuba and Iran becoming a particular importance. In particular relations between Venezuela and the United States deteriorated markedly as Chávez became highly critical of the U.S. foreign policy, opposing the U.S.-led invasion of Iraq in 2003 and condemning the NATO–led military intervention in Libya. Relations thawed somewhat under President Barack Obama in June 2009, only to steadily deteriorate once again shortly afterwards. Chávez also focused on a variety of multinational institutions to promote his vision of Latin American integration, including Petrocaribe, Petrosur, and TeleSUR. Bilateral trade relationships with other Latin American countries also played a major role in his policy, with Chávez increasing arms purchases from Brazil, forming oil-for-expertise trade arrangements with Cuba, and creating unique barter arrangements that exchange Venezuelan petroleum for cash-strapped Argentina's meat and dairy products. He also befriended pariah states such as Belarus and Iran. Domestic mishandling of the country under Chávez prevented Venezuela from strengthening its position in the world.
