Since he returned to office in January, Brazil's President Luiz Inacio Lula da Silva has traveled to 21 countries and met with more than 50 heads of state, including two kings and the Pope.

The globe-trotting leftist leader, the first head of state to address the United Nations General Assembly on Tuesday, has prioritized foreign trips in his third term so far as he strives to restore his country as a global player.

"Brazil is back," he repeats in speeches across five continents, in contrast with the growing isolation that came with his predecessor Jair Bolsonaro's hard-right political stance and dismal environmental record.
