As the world celebrates former vice president Joe Biden's victory in the presidential race, two Latin American leaders held out their congratulatory remarks.

Brazilian President Jair Bolsonaro has kept quiet on President Donald Trump's loss.

The same also goes for Mexican President Andrés Manuel López Obrador, who refuses to congratulate Biden, saying that he would wait until the legal challenges over the election were resolved, as reported by the Associated Press.

Bolsonaro has been dubbed "the Trump of the Tropic" with his populist, off-cut style.

The two Latin American leaders and Trump are reported to be connected with some similarities. All three leaders dislike mask mandates during the COVID-19 pandemic.

They were also loosely described as populist and nationalist. However, the motives of the two Latin American presidents may differ.

Brazil's Leader

Bolsonaro and his sons seem to be uncomfortable with the result of the U.S. presidential race, according to the AP.

Like Trump's children, Bolsonaro's children play a role in the country's political scene.

Bolsonaro earlier expressed his support for Trump's reelection. His son also wore hats with the writing "Trump 2020."

His son, Congressman Eduardo Bolsonaro, has posted images on social media, being skeptical about how Biden's votes rose so quickly in later counts.

Bolsonaro's other son also questioned networks' decision to cut away from Trump's speech on Wednesday, claiming a vote fraud.

The younger Bolsonaro called the move an attack on freedom of speech.

A senior official of the Brazilian Embassy in the U.S. said that Brazilian leaders fear that claims by Bolsonaro or his sons could affect the U.S.-Brazil relations.

The official refused to be named for fear of reprisals. Bolsonaro then tried to adopt a more pragmatic tone on the matter since Wednesday, following his advisers' advice.

Mexico's Leader

Meanwhile, López Obrador had a pleasant relationship with Trump, which can be an unusual thing for a left-leaning politician.

The Mexican president is one of the few world leaders ready to congratulate Trump.

"President Trump has been very respectful of us, and we have reached very good agreements, and we thank him because he has not interfered and has respected us," López Obrador said in an AP report.

He did not meet with Biden or his campaign team during his recent trip to the U.S. But López Obrador claimed that Biden had "very good relations" with him.

Democrat representative for Texas' 20th District Joaquin Castro tweeted on his Twitter account in Spanish that the Mexican president's unwillingness to congratulate Biden shows a true diplomatic failure on López Obrador.

This was in "a moment in which the incoming Biden administration is seeking to start a new era of friendship and cooperation with Mexico," Castro further said.

Mexican singer Juan Gabriel also questioned López Obrador's move, noting that Trump will be president for two more months, while Biden will be president for four more years.

Gabriel added that they had started the relationship on the wrong foot.

Past U.S. Ambassador to Mexico Antonio Garza disagreed, saying that it will hardly matter on the inauguration day.
