The Chilean government is struggling to preserve output and growth in its crucial copper mining sector amid an economic slowdown . Chile is the top producer of copper in the world, yielding 5.7 million metric tons of the metal per year, more than 30 percent of global output. Roughly 20 percent of government revenue comes from copper, and copper and copper products made up 47 percent of the country's exports in 2014. The country experienced a copper boom coinciding with the wider Latin American commodities boom of the 2000s, when higher Chinese demand for commodities such as oil, iron ore, copper and soybeans spurred growth in Latin American economies. As Chinese demand for commodities increased, the average price of copper skyrocketed, growing from $1.87 per pound in 2005 to $4.05 per pound in 2011.
