In September 2010，Venezuela held the National Assembly election to elect the 165 deputies. The United Socialist Party of Venezuela （its Spanish acronym is PSUV），the ruling party，failed to gain a two-thirds supermajority. Venezuela was one of the worst performers in Latin American and the Caribbean in 2010，whose GDP contracted by 1.6% in the year. In the mean time，it was suffering from the extremely heavy inflation pressure. To improve the social development，the Chavez government continued to implement the social mission. Diplomatically Venezuela forged strong ties with Russia and Iran and served as an engine of the regional integration. But its relationship with the United States was still highly tense.
