Argentina is currently holding the rotating presidency of Mercosur.
During her subsequent visit to Chile on Tuesday, the High Representative will meet President Michelle Bachelet, Minister of Foreign Affairs Heraldo Muñoz and the Executive Secretary of the Economic Commission for Latin America and the Caribbean Alicia Bárcena.
The visit will be a chance to further deepen and strengthen the already strong ties between the European Union and Latin America.
Argentina and Chile are important partners of the EU in a wide spectrum of areas, from foreign policy to trade and investment, and closely cooperate in multilateral fora on global issues such as climate change and security.
This visit comes ahead of the Summit of the Community of Latin American and Caribbean States, which will take place in El Salvador in October 2017.
