In the 2011 edition of its traditional index Corruption Perceptions Index (CPI), only three of the twenty Latin American countries in the area approved in perceived transparency of its public sector. "Chile marks the line and the other countries of Latin America followed slowly. This is a compliment for Chile, but also a recommendation for the imposition of higher barriers, "he said in remarks to Efe Americas director of IT, Alejandro Salas. In his view, most Latin American countries that score low on the table suffer from a "weak institutions" where the government or major political actor - "regardless of whether the left or right" - is "very strong", so "there is no balance of power." The worst scores on a scale from 0 (highly corrupt) to 10 (very transparent), Chile (7.2) ranked 22 out of 183 countries surveyed, Uruguay (7.9) 25 and Puerto Rico (5.6) for 39, while Nicaragua (2.5), Paraguay (2.2 ) and Venezuela (1.9) occupied caboose at positions 134, 154 and 172, respectively. Next to the approved positioned Costa Rica (4.8) and Cuba (4.2), followed by Brazil (3.8), ahead of China - Colombia (3.4), El Salvador (3.4), Peru (3.4) and Panama (3.3). Argentina and Mexico remain in the 3.0 out of ten, the level of Malawi and Indonesia, and then placed in the ranking achieved Bolivia (2.8), Ecuador (2.7), Guatemala (2.7), Dominican Republic (2.6) and Honduras (2.6). Compared to last year, most Latin American countries analyzed showed minor variations, except Cuba positive and El Salvador, which recorded increases of substance, and the decline in Costa Rica. Cuba advanced positions in Cuba dates back eight positions and five-tenths, from position 69 to 61 and 3.7 to 4.2 points, El Salvador jumps 47 positions and nine tenths with respect to IT report 2010 and gives Costa Rica, meanwhile, five tenths and nine positions. Salas believes that the reforms of Cuban President Raul Castro , have helped the perception of their country, the head of the Salvadoran state, Mauricio Funes, is working towards greater transparency at national and regional levels and that the image of Costa Rica has been affected by scandals of recent years and have started to be part of "The route of drug trafficking." Globally Globally, Somalia (1.0), North Korea (1.0) and Myanmar (Burma) (1.5) are the most corrupt countries according to the CPI, and New Zealand (9.5), Denmark (9.4) and Finland (9.4) the least hit by this type of practice. In comparison, Spain (6.2) was in the thirty-first position, with little variations from the previous year's study. IT global benchmark analysis transparency, warns in its report that only 49 of the 183 countries studied the exam, even though the citizen outcry against these practices has gained momentum around the world. "This year we have seen corruption allegations in the demonstrations rich and poor. Both in the European debt crisis and in the Arab world, leaders must address the demands for better government, "he said in a statement the president of TI, Huguette Labelle. TI says in his report that the protests around the world, "fueled by corruption and political instability", "clearly show that citizens feel that their leaders and public institutions are not sufficiently transparent or accountable." CPI is produced each year from 1995 to from different studies and surveys on perceived levels of corruption in the public sector in different countries.
