While many world leaders were quick to congratulate Joe Biden on his US election victory, others have appeared not so pleased.
Several prominent figureheads who have maintained warm relations with President Donald Trump have remained notably silent following the Democrat's historic win alongside his running mate Kamala Harris.
Sky News highlights some of the most notable leaders yet to have offered their well wishes to America's next top leadership team.
Jair Bolsonaro, Brazil
Mr Bolsonaro even took aim at Mr Biden following the first TV debate in the presidential race after the former vice president said Mr Trump needed to push Brazil to do more to protect the Amazon.
The Brazil leader dubbed Mr Biden's statement as "disastrous".
But Mr Bolsonaro is said to be distancing himself from Mr Trump after the election result, reportedly saying he is "not the most important person in the world", according to The Washington Post.
"The most important person is God," Mr Bolsonaro was quoted as saying.
Vladimir Putin, Russia
There has also been no immediate reaction from Russian President Vladimir Putin, who was friendly with Mr Trump.
He waded into Mr Trump's impeachment trial last year, defending the president and describing the situation as "far-fetched" and "fabricated".
Mr Trump sparked outrage on both sides of the political dive in Washington following his first summit with Mr Putin.
The US president was accused of "treasonous" behaviour during a 2018 news conference with his Russian counterpart in Finland, in which he contradicted his own intelligence officials over alleged meddling by Moscow in the election that put him in the White House.
Janez Jansa, Slovenia
In the homeland of First Lady Melania Trump, Slovenian Prime Minister Janez Jansa congratulated Mr Trump on a victory before all votes were counted.
He has continued to show support despite Mr Biden being announced the winner.
Other leaders that have openly supported Mr Trump during his term have not taken the same attitude, however.
Israeli Prime Minister Benjamin Netanyahu, whose Twitter profile picture shows him sitting beside Mr Trump, offered his congratulations to Mr Biden and described him as a friend of Israel.
He added that he was looking forward to working with him and Mrs Harris to strengthen the "special alliance" between the two countries.
In a separate statement, he thanked Mr Trump for raising US-Israeli relations to "unprecedented heights".
He added: "The US is our most important ally and I look forward to working closely together on our shared priorities from climate change to trade and security."
And Saudi Arabia's leaders have also congratulated Mr Biden - although it took a while.
On Sunday - more than 24 hours after the race was called - King Salman bin Abdulaziz and the crown prince congratulated the president-elect and vice president-elect, according to state news agency SPA.
The crown prince enjoyed a warm relationship with Mr Trump, who offered his backing following the murder of Saudi journalist Jamal Khashoggi.
Mr Khashoggi, a staunch critic of the Saudi rulers, was killed inside the Saudi consulate in Istanbul in October 2018, having entering to obtain documents so he could marry his Turkish fiancee.
