the La Moneda Palace in Santiago, where they agreed to send two commissions to Bolivia: one to mediate between the executive and the opposition, and another to investigate the killings in Pando Department. Cuba visit In February 2009, Bachelet visited Cuba and met with Fidel Castro. There she urged the United States to put an end to the embargo. No Chilean head of state had visited the country in 37 years. Soon after the meeting, Castro wrote that the "fascist and vengeful Chilean oligarchy is the same which more than 100 years ago robbed Bolivia of its access to the Pacific and of copper-rich lands in a humiliating war." Progressive Leaders summit In March 2009, Bachelet hosted in Viña del Mar the "Progressive Leaders Summit", meeting with U.S. Vice President Joe Biden, British Prime Minister Gordon Brown, Spanish Prime Minister José Luis Rodríguez Zapatero and presidents Tabaré Vázquez of Uruguay, Luiz Inacio Lula da Silva of Brazil and Cristina Fernández de Kirchner of Argentina. The meeting garnered some media interest because it took place six days before the highly anticipated G-20 Summit in London. Trade Continuing the coalition's free-trade strategy, in August 2006 Bachelet promulgated a free trade agreement with the People's Republic of China (signed under the previous administration of Ricardo Lagos), the first Chinese free-trade agreement with a Latin American nation; similar deals with Japan and India were promulgated in August 2007. In October 2006, Bachelet promulgated a multilateral trade deal with New Zealand, Singapore and Brunei, the Trans-Pacific Strategic Economic Partnership (P4), also signed under Lagos's presidency. She held free-trade talks with other countries, including Australia, Vietnam, Turkey and Malaysia. Regionally, she signed bilateral free trade agreements with Panama, Peru and Colombia. Other policies In October 2007, Bachelet granted amnesty to undocumented migrants from other Latin American countries. The measure was expected to benefit around 15,000 Peruvians and 2,000 Bolivians. In December 2007 she signed in Bolivia a trilateral agreement with the presidents of Brazil and Bolivia to complete and improve a 4,700 km road to connect the Atlantic and Pacific Oceans, via Arica and Iquique in Chile and Santos in Brazil. In May 2008, following months of intense lobbying, Chile was elected as member of the United Nations Human Rights Council, obtaining the largest vote among Latin American countries. In December 2009 Chile became the first country in South America, and the second in Latin America
