North American Leaders' Summit
The North American Leaders' Summit (NALS), called the Three Amigos Summit in the English language popular press, Cumbre de los tres amigos in Spanish and Sommet des trois amigos in French, is the trilateral summit between the prime minister of Canada, the president of Mexico, and the president of the United States. The summits were initially held as part of the Security and Prosperity Partnership of North America (SPP), a continent-level dialogue between the three countries established in 2005, and continued after SPP became inactive in 2009.
