The Andean nation has long prided itself on its embrace of free trade. It was an enthusiastic advocate of the now-stalled Trans-Pacific Partnership (TPP) and has signed more than a dozen bilateral agreements, including with the European Union, China and Japan, accords credited with helping Peru become one of Latin America’s best-performing economies. One of the mainstays of that growth has been Lima’s trade pact with Washington. Since it took effect in 2009, U.S.-Peruvian commerce has boomed from just under $9 billion in 2010 to nearly $14 billion in 2015, helping haul millions out of poverty here and establishing Peru as an upper-middle-income nation.

Americans, meanwhile, have benefited from increased access to Peruvian goods, everything from organic artichokes and quinoa to gold, silver and other metals mined in the Andes.

Yet those gains could be at risk if President-elect Donald Trump follows through on his campaign promise to renegotiate U.S. trade deals, in particular the bilateral Peru treaty.
