Services account for 53% of Peruvian gross domestic product, followed by manufacturing (22.3%), extractive industries (15%), and taxes (9.7%). Recent economic growth has been fueled by macroeconomic stability, improved terms of trade, and rising investment and consumption. Trade is expected to increase further after the implementation of a free trade agreement with the United States signed on 12 April 2006. Peru's main exports are copper, gold, zinc, textiles, and fish meal; its major trade partners are the United States, China, Brazil, and Chile.
