Pacific Alliance

The Pacific Alliance (Alianza del Pacífico) is a regional integration initiative launched by the Declaration of Lima on 28 April 2011 and formally constituted by the Framework Agreement signed in Paranal, Chile, on 6 June 2012. Its four full members are Chile, Colombia, Mexico, and Peru — all Pacific-facing Latin American economies with market-oriented trade policies and pre-existing bilateral free trade agreements with one another.

The bloc's stated objectives are to build an area of deep integration enabling the free movement of goods, services, capital, and persons; to drive growth and competitiveness; and to project members collectively toward the Asia-Pacific. A key operational instrument is the Additional Protocol to the Framework Agreement, signed in Cartagena in February 2014 and in force since 1 May 2016, which eliminated tariffs on roughly 92% of intra-bloc trade with the remainder phased out over time.

Distinctive features include:

• Visa-free travel among member nationals for tourism and business stays.
• MILA (Mercado Integrado Latinoamericano), the integrated stock exchange linking the Santiago, Lima, Bogotá, and (later) Mexican bourses.
• A single shared diplomatic presence in some third countries.
• A large roster of Observer States — over 60 — reflecting wide diplomatic interest.

The Alliance also created an Associated State category for non-Latin American partners negotiating deeper trade ties. Costa Rica has long been considered a candidate for full membership but accession has stalled. Ecuador's accession process advanced under President Lenín Moreno but has not been concluded. Singapore was the first country to complete negotiations to become an Associated State, signing the agreement in 2022.

The Alliance operates through rotating pro tempore presidencies and presidential summits rather than a permanent secretariat, distinguishing it institutionally from Mercosur or the Andean Community. Critics note that intra-bloc trade remains a modest share of members' total commerce, and political turnover — particularly Mexico's reduced engagement under President López Obrador — has slowed momentum.
