RIO DE JANEIRO β€” Brazil pushed for concerted action to alleviate hunger Monday as it hosted a summit of the Group of 20 leading economies amid global uncertainty over two major wars and incoming U.S. President-elect Donald Trump.

Brazilian President Luiz InΓ‘cio Lula da Silva welcomed foreign leaders to Rio de Janeiro’s modern art museum Monday morning and delivered an opening address that focused on fighting food insecurity.

β€œIt is for those of us here, around this table, to face the undelayable task of ending this stain that shames humanity,” Lula told his colleagues. β€œThat will be our biggest legacy.”

Heightened global tensions and uncertainty about an incoming Trump administration ahead of the summit already tempered expectations for a strongly worded statement addressing the conflicts in the Middle East and between Russia and Ukraine.

Rio de Janeiro is seen Sunday prior to hosting the G20 Summit on Monday and Tuesday.

Further dimming prospects, G20 officials said Argentina’s negotiators started challenging some of the draft language.

That left experts anticipating a final document focused on social issues like the eradication of hunger β€” one of Brazil’s priorities β€” even if it still aims to include at least a mention of the ongoing wars.

β€œBrazilian diplomacy has been strongly engaged in this task, but to expect a substantively strong and consensual declaration in a year like 2024 with two serious international conflicts is to set the bar very high,” said Cristiane Lucena Carneiro, an international relations professor at the University of Sao Paulo.

After Lula thwarted far-right former President Jair Bolsonaro’s reelection bid in 2022, there was some excitement in the international community at the prospect of the leftist leader and savvy diplomat hosting the G20.

Bolsonaro had little interest in international summits, let foreign policy be guided by ideology and clashed with several leaders, including French President Emmanuel Macron. Lula took office and often quoted a catchphrase: β€œBrazil is back.”

Under Lula, Brazil reverted to its decades-old principle of nonalignment to carve out a policy that best safeguards its interests in an increasingly multipolar world, even as his administration’s foreign policy at times raised eyebrows.

Two officials from Brazil and one from another G20 nation who spoke on condition of anonymity said Argentine negotiators are standing in the way of a joint declaration.

Two of them said Argentina’s negotiators raised several objections to the draft, most vehemently opposing a clause calling for a global tax on the superrich β€” which they previously accepted, in July β€” and another promoting gender equality.

Last month, Argentina alone opposed a declaration of the G20 working group on female empowerment, preventing consensus. While Lula received heads of state Monday with smiles and warm embraces, he and Argentina’s right-wing President Javier Milei stood at arms’ length while briefly shaking hands. Milei is an avid Trump supporter.

Trump’s win in the U.S. presidential election this month and the imminent return of an β€œAmerica First” doctrine could also hamper the diplomatic spirit needed for broad agreement on divisive issues, analysts said.

Ambassador Mauricio Lyrio, Brazil’s key negotiator at G20, told reporters this month that Lula’s launch of a global alliance against hunger and poverty on Monday is just as important as the final statement. As of Monday, 82 nations signed on to the plan, Brazil’s government said. It is also backed by organizations including the Rockefeller Foundation and the Bill & Melinda Gates Foundation.

A demonstration Sunday on Rio’s Copacabana beach featured 733 empty plates spread across the sand to represent the 733 million people who went hungry in 2023, according to United Nations data, and calling on leaders to take action.

β€œBrazil wanted a global deal to fight poverty, a project to finance green transition and some consensus over a global tax for the superrich. Only the first one has survived,” said Thomas Traumann, a former government minister and a political consultant based in Rio.

Be that as it may, Lula reiterated his call for a tax on billionaires at the start of leaders’ afternoon session.

β€œTaxation of 2% on the total assets of superrich individuals could generate funds of about $250 billion per year to be invested in facing up to social and environmental challenges all over the world,” Lula said.

U.S. President Joe Biden attended the summit after a stop in Lima for the Asia-Pacific Economic Cooperation forum. He also traveled over the weekend to Manaus, a city in Brazil’s Amazon rainforest. It was the first time a sitting American president set foot in the Amazon.

The White House announced a $50 million contribution to the Amazon Fund, the most significant international cooperation effort to preserve the rainforest, after a prior $50 million commitment. Biden’s administration announced plans last year to give $500 million.

White House officials say Biden also would use the summits to press allies to not lose sight of finding an end to the wars in Lebanon and Gaza and to keep up support for Ukraine as it tries to fend off Russia’s invasion.
