Fernandez on CNN: Milei presents himself as a "Trumpist" 1:19

(CNN Español) -- Javier Milei was sworn in as president of Argentina on Sunday and received the mandate from the now former president, Alberto Fernández.

Throughout the election campaign, the leader of La Libertad Avanza made controversial statements about some world leaders, including Luiz Inácio Lula da Silva, whom he called a "communist." On more than one occasion, Milei also spoke of his eventual government's international alliances, limiting them to the United States and Israel.

This is the list of global leaders who participated in the inauguration ceremony of his government.

Luis Lacalle Pou, Uruguay

The president of Uruguay is one of the leaders who was there this Sunday. Lacalle Pou traveled to Buenos Aires on Saturday, the president's press officer told CNN.

His presence at the handover ceremony was confirmed last Wednesday by the Minister of the General Secretariat of Government, Camila Vallejo. "That decision has been made, the president represents the State of Chile and, as has always been done, he is going to attend," Vallejo said in a conversation with the media.

"It is a standard that the president has for all cases: to build and strengthen diplomatic relations with all countries regardless of whether or not we are related to a particular government," Vallejo said.

Santiago Peña, Paraguay

Peña was one of the leaders present at the ceremony, as confirmed by Paraguayan Foreign Minister Rubén Ramírez Lezcano in an interview with a local media. "President Peña accepted President Javier Milei's invitation to attend the handover ceremony on December 10 in Buenos Aires."

On behalf of the Paraguayan people, I greet our brotherly people in Argentina for an exemplary election day. I congratulate @JMilei on his victory and offer Paraguay's cordial and fraternal hand to strengthen relations between our countries. To the great Argentinian people, cheers!

The Honduran vice president traveled to Buenos Aires on behalf of President Xiomara Castro, the Honduran Foreign Ministry said in a statement.

King Felipe VI of Spain

The presence of the Spanish monarch, Felipe VI, was confirmed last Friday, according to the Télam news agency citing the Zarzuela Palace.

Other political figures who will participate in the ceremony

Jair Bolsonaro, former president of Brazil

The former president has been one of those who most celebrated the victory of the Liberal. His son, Congressman Eduardo Bolsonaro, traveled to the country on the occasion of the first round of elections, to accompany Milei while he waited for the results of the election day.

On November 20, after the victory in the second round, Jair Bolsonaro wrote on his Twitter account: "I had a phone call from Javier Milei, in which I congratulated him on his victory, while I was invited to the inauguration." "Today Argentina represents a lot for all those who love democracy and breathe freedom," he added.

On Tuesday, the former president made a request to the Supreme Court of Justice to travel to Argentina, which confirmed his presence in the country. "In view of the ongoing investigations and with deep respect for this Court, the petitioner goes to the file to inform that he will be temporarily absent from the country for the period between December 7 and December 11," the petition reads. This is a necessary formal process given the investigations that are being carried out against the former president, although he is not considered a ban on leaving the country, according to CNN Brasil.

Santiago Abascal, president of VOX

The president of Spain's far-right VOX party, Santiago Abascal, was also invited to Sunday's ceremony, several Spanish newspapers reported. On Wednesday, the press department of the Disenso Foundation, which is organizing the delegation's trip, confirmed to CNN that Abascal will travel to Buenos Aires.

Abascal was one of the first political leaders to congratulate Milei on his victory, with a Nov. 19 message accompanied by a photograph of the two. "Congratulations dear Javier Milei on your great victory in the Argentine presidential elections. Today opens a path of future and hope for Argentines and all of Latin America, which we celebrate in Spain with special joy. Long live Spain, long live Argentina, long live free of socialism and sovereign!" he wrote at the time.

The leaders who did not attend

Luiz Inácio Lula da Silva, President of Brazil

Lula da Silva did not attend Sunday's ceremony, Brazilian Social Communication Minister Paulo Pimenta told the Telam news agency. "Lula will not go to Buenos Aires," Pimenta replied in response to a query from the Argentine news agency. The Press Secretary of the Planalto Palace told Télam that the Brazilian government will be represented by Foreign Minister Mauro Vieira, who was ambassador to Buenos Aires for eight years.

Joe Biden, United States

A spokesperson for Milei told CNN that Joe Biden would not be present at the inauguration ceremony due to other commitments on his schedule. Last week, Milei arrived in the United States with a small entourage, in what was his first trip as president-elect. During his visit, he held meetings with officials from the White House and the Treasury Department.

The U.S. delegation was led by Secretary of Energy Jennifer Granholm and includes Ambassador to Argentina Marc Stanley, Under Secretary of Transportation for Policy Carlos Monje, Under Secretary of Energy for International Affairs Andrew Light, and NSC Senior Director for the Western Hemisphere Juan Sebastian Gonzalez.

Daniel Ortega, Nicaragua

Days before Javier Milei's inauguration, Nicaragua's Foreign Ministry announced that it will withdraw its ambassador from Argentina, Carlos Midence, citing "repeated statements and expressions of the new rulers."

Nayib Bukele, El Salvador

Although Bukele was one of those who congratulated Milei on his victory and did not hide his sympathy for the libertarian, the week before the election from the communication of the presidency of El Salvador confirmed to CNN that the president would not be part of the party that will attend the ceremony.

Bukele is on leave from the Legislative Assembly to dedicate himself to the electoral campaign for re-election in the February 4 elections, in a candidacy whose constitutionality is questioned by the opposition.
