(Bloomberg) -- Mexico called for delaying the election of a new chief for a key Latin American development bank amid controversy caused by U.S. President Donald Trump’s push to have a close ally at the helm of the institution.

Mexico’s finance ministry announced Friday its support for a postponement of the vote on the next president of the Inter-American Development Bank, expected next month, saying the issue requires more dialog to decide the role for the institution amid the global pandemic. The move comes after the European Union and then Chile said they support a vote delay.

Postponing the election would be a setback for Trump, who in June launched his senior adviser for Latin American issues Mauricio Claver-Carone to head the Washington-based institution. While Claver-Carone portrays himself as a breath of fresh air for an organization that has had just four chiefs in six decades, his eventual presidency would also mean breaking a non-written tradition where a Latin American heads this bank.

The move triggered criticism from politicians and former diplomats in the region including Brazil’s Fernando Henrique Cardoso and Colombia’s Juan Manuel Santos, who in June penned a letter calling for country members to reject the U.S. nomination.

Mexico’s statement on Twitter didn’t mention the U.S. candidate specifically and cited the inability of governors of the IDB, as the institution is known, to meet in person; their March annual meeting was postponed due to the virus. While the U.S. is the biggest shareholder with a 30% stake and has a de facto veto based on quorum requirements, the winner needs support from more than half of the region’s 28 member countries.

The coronavirus pandemic has boosted the importance of the bank, as it plans to lend billions of dollars to help Latin American nations recover.

Claver-Carone’s election would place a Trump ally at the top of the IDB for the next half decade, even if Trump loses his re-election bid in November. The U.S. seized the opportunity after Latin America’s three largest economies failed to agree on a candidate. While Argentina secured the support of Mexico for Gustavo Beliz, an adviser to President Alberto Fernandez, Brazil initially planned to present its own candidate.

Mexico’s decision comes one month after President Andres Manuel Lopez Obrador traveled to Washington to see Trump for a visit, officially to celebrate the start of a new North American free trade agreement, that was widely criticized in Mexico after Trump spent part of his 2016 campaign and part of his time in office verbally attacking the nation and its people.
