Foreign-direct investment (FDI) to Latin America grew by $20 billion in 2012 to $173 billion, and reached 3 percent of the region’s GDP – up from 2.7 percent last year. These are the findings of the most recent FDI-GDP ranking by Latin Business Chronicle. The index measures the relative influence of foreign investment in 19 of Latin America’s economies by measuring it as a percentage of a country’s total GDP.
