KYIV, Ukraine (AP) — Ukrainian President Volodymyr Zelenskyy is heading to Buenos Aires to witness the swearing-in on Sunday of Argentina’s new president, Javier Milei, Zelenskyy’s office said.

It is the Ukrainian leader’s first-ever trip to Latin America as Kyiv continues to court support among developing nations for its 21-month-old fight against Russia’s invading forces.

A political outsider who has railed against what he calls entrenched official corruption in Argentina and promised to uproot the political establishment, Milei ran on a pro-Western foreign policy platform, repeatedly expressing distrust of Moscow and Beijing.

Zelenskyy phoned Milei shortly after the Argentinian’s electoral victory, thanking him for his “clear support for Ukraine” which he described in social media posts as “well-noticed and appreciated by Ukrainians.”

In its readout of the call published shortly later, Milei’s office said he had offered to host a summit between Ukraine and Latin American states, a potential boon to Kyiv’s monthslong effort to strengthen its relationships with countries of the global south.

Zelenskyy and other senior Ukrainian officials have repeatedly presented Ukraine’s war against Russia as resistance against colonial aggression, hoping to win support from Asian, African and Latin American states that in the past struggled to free themselves from foreign domination, sometimes turning to Moscow for support against Western powers.

According to Zelenskyy’s official website, he broke his journey to Argentina to meet with the prime minister of the West African country of Cape Verde, Ulisses Correia e Silva, thanking him for his support for Kyiv’s diplomatic initiatives and discussing efforts to boost Ukrainian grain exports to Africa. It was not immediately clear where the meeting took place.

Zelenskyy expressed his appreciation for Cape Verde’s backing of UN resolutions supporting Ukraine’s territorial integrity and calling for the withdrawal of Russian troops from Ukrainian territory before peace talks can begin.

The African country previously supported UN documents condemning Russia’s annexation of Crimea from Ukraine in 2014.

According to Zelenskyy’s website, he and Correia e Silva also discussed Kyiv’s efforts to expand a corridor for grain exports in the Black Sea that has seen over 7 million metric tonnes of Ukrainian produce shipped out since its inception, months after Moscow pulled out of a UN-brokered deal to facilitate shipments of Ukrainian and Russian food and fertilizer to countries in need, as well as a proposal to establish transport and storage hubs for Ukrainian grain in Africa.
