Blinken will head to Brasilia, Rio de Janeiro and Buenos Aires from Feb. 20 to 23 as Brazil hosts the G20 Foreign Ministers Meeting as part of its presidency of the group gathering the world's largest economies.

He will meet Brazilian President Luiz Inacio Lula da Silva in Brasilia to discuss the U.S.-Brazil partnership for workers rights and cooperation on the energy transition, the State Department said, before traveling to Rio for the G20 meeting.

In Rio, he expects to "engage world leaders on our shared initiatives for increasing peace and stability" and address international efforts to support Haiti as the country grapples with an escalating humanitarian crisis and spikes of violence.

Blinken will then head to Buenos Aires for a meeting with Argentine President Javier Milei, a right-wing libertarian who was sworn in December pledging a "shock therapy" to stabilize the country's embattled economy.

Blinken and Milei will discuss "sustainable economic growth, our shared commitment to human rights and democratic governance, critical minerals, and enhancing trade and investment," the State Department said in a statement.
