Background and career
Luis Guillermo Solís Rivera (Spanish pronunciation: [lwis ɣiˈʝeɾmo soˈlis riˈβeɾa]; born 25 April 1958) is a Costa Rican political scientist, historian and politician who served as the 47th President of Costa Rica from 2014 to 2018. A member of the Citizens' Action Party, he has had an academic career spanning more than three decades. Solís led the first round of the 2014 presidential election and went on to win the presidency by a landslide, receiving the highest number of votes ever obtained by a presidential candidate in Costa Rican history. His election marked the first time that a member of the PAC assumed the presidency. At the time of his election, he was a full professor at the University of Costa Rica, where he had taught since 1981. Since May 2017, Solis has been under fire after a report accused him of allegedly corruptly expediting the legal process of Chinese cement imports in favor of businessman and owner of Sinocem, Juan Carlos Bolaños, in a case known as Cementazo. In May 2018 the Public Prosecutor of Costa Rica dismissed the charges against him.
Solís was born in San José, Costa Rica, to Vivienne Rivera Allen, an educator, and Freddy Solís Avendaño, an uneducated shoemaker. Both his parents lived in Turrialba, and as such many residents consider him Turrialban. His maternal grandmother's family has Afro-Caribbean and Chinese roots, coming from Jamaica to Costa Rica in the early 1900s. Solís grew up in San Pedro de Montes de Oca and Curridabat, neighborhoods of San José. He attended Methodist High School in San José, where he was president of the student body, before studying history at the University of Costa Rica, where he earned a degree with academic honors in 1979. He earned a master's degree in Latin American Studies at Tulane University in New Orleans. Solís has held various academic and consulting positions. Between 1981 and 1987, he was an associate professor at the University of Costa Rica. In addition, he was a Fulbright Scholar at the University of Michigan from 1983 to 1985. During this time, Solís worked with the Arias administration and eventually became director of the Center for Peace and Reconciliation (CPR for its Spanish initials). From 1992 to 1995, Solís worked with the Academic Council of the United Nations System. Starting in 1999, Solís worked for Florida International University as coordinator in the Center for the Administration of Justice and as a researcher for the Latin American and Caribbean Center, where he analyzed political and social events in Latin America. A writer and editorial writer, Solís has published numerous essays and books about national and international affairs. In the 1990s, he wrote for La República, a daily newspaper based in San José. His writing has been published by Foreign Affairs Latinoamérica, Frontera Norte, Espacios and Global Governance. His writing has focused on civil society, international relations, and trade. Solís is a member of the Inter-American Dialogue.
While still at UCR, Solís joined the National Liberation Party (PLN for its Spanish initials) in 1977. Solís was an adviser to Óscar Arias in the Foreign Ministry, working on the Esquipulas Peace Agreement for which Arias would later win a Nobel Peace Prize. Solís served as Director of International Relations for the PLN. During José María Figueres Olsen's time in office, Solís was ambassador of Central American Affairs. In 2002, Solís followed Rolando González Ulloa as General Secretary of the PLN, a position he resigned from the following year, citing his disappointment with the Alcatel-Lucent bribery scandal that many PLN leaders were involved in. In 2005, he denounced the PLN for irregularities and corruption during party elections, along with a host of former PLN members. Solís went as far as to call the PLN leadership "Napoleonic" and "anti-democratic". He officially renounced his affiliation with the party and returned to academics. After the 2006 election, Solís' name began to come up in PAC circles, particularly at meetings of the "ungroup," an informal gathering of PAC officials, led by former deputy and former Vice President of the National University of Costa Rica Alberto Salom Echeverría. Ottón Solís, one of PAC's founders and three-time presidential candidate, suggested that Luis Guillermo Solís run as a vice presidential candidate in 2010. Luis Guillermo Solis rejected the offer because he was working for the General Secretariat of Ibero-America (SEGIB for its Spanish initials), and employees of SEGIB were not allowed to participate in elections. In 2009, Luis Guillermo Solís began his official affiliation with PAC. He began attending meetings of the "ungroup" in 2010. Within the party, PAC leader María Eugenia Venegas recognized Solís' potential and pushed for him to be elevated within the party. Solís undertook several trips around the country to meet with national and provincial PAC leaders.
Solís announced his candidacy for president on 27 November 2012. In the PAC's primary, he ran against Epsy Campbell Barr, Juan Carlos Mendoza García, and Ronald Solís Bolaños, winning with 35 percent of the vote, only 110 votes more than Juan Carlos Mendoza García. In October 2013, he chose Helio Fallas and Ana Helena Chacón Echeverría as his Vice-Presidential running mates. Among his aims, Solís claimed he would clean up corruption, create major investments in infrastructure, and shore up Costa Rica's universal health care and social security system. He also promised to continue initiatives to keep Costa Rica environmentally friendly. He said that he would "put the brakes" on new free trade agreements and would begin correctly administrating current free trade agreements. As such, Solís received a tremendous amount of political support from the country's trade unions. On 2 February 2014, Solís won the most votes in the election with 30.95 percent. PLN candidate Johnny Araya came second with 29.95 percent of the vote. Most of Solís' support came from the Central Valley provinces of San José, Alajuela, Heredia and Cartago.
Because no candidate exceeded 40 percent of the vote, a runoff was scheduled for 6 April, as required by the constitution. However, on 5 March, Araya announced that he would abandon his campaign after polls showed him far behind Solís; one poll showed him losing by over 43 percent. However, under Costa Rican law the runoff still had to take place, and Solís won with over 77 percent of the vote, the largest margin ever recorded for a free election in Costa Rica. Unlike the first round, Solís earned a majority in every province, including Puntarenas, Limón, and Guanacaste. When he took office on 8 May, he was the first president in 66 years not to come from the PLN or what is now the PUSC. Immediately after the election, Solís thanked Costa Rican voters. He received congratulatory notes from world leaders, including US Secretary of State John Kerry, Ecuadoran President Rafael Correa, Mexican President Enrique Peña Nieto, Venezuelan President Nicolás Maduro, Bolivian President Evo Morales, and the spokesperson from the French Ministry of International Affairs. For his part, Araya congratulated Solís on his victory, calling for national unity.
A little over a week before taking office, in April 2014, Solís announced the creation of his cabinet. His cabinet consists of mostly PAC members or non-aligned citizens. However, two PUSC members were also added: María del Rocío Sáenz, Abel Pacheco's former health minister, heads the Costa Rican Social Security System (Caja Costarricense del Seguro Social). Delia Villalobos, another former health minister, heads the Social Protection Council (Consejo de Seguridad). Solís took office on 8 May 2014, amid festive fanfare. Delegations from more than 80 countries attended his inauguration at La Sabana Metropolitan Park, including Prince Felipe de Borbón of Spain, Evo Morales of Bolivia, Rafael Correa of Ecuador, and the Secretary General of the Organization of American States, José Miguel Insulza. Solís said, in Costa Rican vernacular, that he is taking over a "weed farm" (finca encharralada), pointing out growing income inequality and poverty, as well as a national teachers' strike.
