Since 2002 when the Venice Commission became an enlarged agreement, the co-operation with the countries and regional organisations in the Americas has been stepped up. Brazil, Chile, Costa Rica, Mexico and Peru joined the Commission as full members, and Argentina and Uruguay as observer states.

The Venice Commission has developed co-operation with countries from the region in such fields as democratic transition, constitution-building, constitutional justice, democratic institutions and electoral legislation and practice through its Sub-Commission on Latin America, which met in 2013 in Mexico City. The 2014, 2015 and 2016 meetings of the Sub-Commission were hosted respectively by Brazil, Chile and Peru. As a result of the growing interest in co-operation in Latin America, the Venice Commission adopted several opinions on draft legislation of Bolivia, Chile, Mexico and Peru. 

Active exchanges have been developed with regional organisations such as the Organisation of American States (OAS), the Inter-American Court of Human Rights, the Inter-American Union of Electoral Organizations (UNIORE) and the Ibero-American Conference of Constitutional Justice (CIJC). Some major standard-setting documents of the Commission have also been translated into Spanish with the support of its Latin American members and the Centre for Constitutional and Political Studies of the Kingdom of Spain (CEPC). The close co-operation between the Venice Commission and the Organisation of American States (OAS) has led to the Co-operation Agreement on advancement and realisation of exchange, co-operation and technical assistance actions related to the further development of the principles of rule of law and separation of powers in Latin America, which was signed in 2020.
