When the U.S.-Peru Trade Promotion Agreement (PTPA) entered into force in 2009, it was presented as a major step forward for protecting international labor rights. Unlike prior trade agreements, most notably DR-CAFTA, the PTPA required both parties not only to enforce their existing labor laws, but also to adopt and maintain laws consistent with 1998 ILO Declaration on Fundamental Principles and Rights at Work and not weaken labor laws in an effort to stimulate the economy or attract foreign direct investment.
