Some observers have attributed the high growth to a public investment boom that was fueled by high oil prices and lending from China. According to the U.S. Energy Information Administration, Ecuador was the third largest source of foreign oil to the western United States in 2014. However, in the middle of 2014 after the price of oil declined significantly, Ecuador’s oil earnings fell. As a consequence, the Economist Intelligence Unit (EIU) forecast that Ecuador’s economy would contract slightly in 2015, although the economy ultimately grew by less than half a percent. President Correa’s plans to begin extracting crude oil from the Ishpingo, Tambochoa, and Tiputini field in Yasuní National Park in the Amazon to provide an economic boost did not salvage the economy from going into recession. In 2016, Ecuador’s gross domestic product contracted by 1.6%.
