• She said she will actively campaign, stressing that she knows the United Nations well enough to reform it and to defend it.
• The field already includes former Chilean president Michelle Bachelet, with Mexican official Alicia Bárcena discussed in reporting as a potential entrant.
• The selection will run through the Security Council and General Assembly before Antonio Guterres departs in late 2026, and an analyst said geopolitical tensions, her background, and Costa Rica’s ties to President Donald Trump could affect support and potential vetoes.
