Already on Saturday, the first congratulations to Joe Biden and Kamala Harris were received.
Canadian Prime Minister Justin Trudeau was out early with a statement, closely followed by both Angela Merkel and Emmanuel Macron.
But not everyone has chosen to congratulate Biden.
Bolsonaro and Erdogan are silent
Brazilian President Jair Bolsonaro belongs to that crowd.
Not unexpectedly, as the leader known as "Tropics Trump" openly chose to support Donald Trump's campaign.
Nor has Turkish President Recep Tayyip Erdoğan wanted to congratulate Biden.
Erdoğan is one of those who is expected to lose the most in a change of power in the White House as the new president is expected to tighten his reins when it comes to the country's foreign policy.
Putin is awaiting official results
Russia's leader Vladimir Putin has previously said he will work with the new president, whoever it is.
However, he has not chosen to congratulate Joe Biden and is not expected to comment before an "official result" is presented, writes the Russian news agency Interfax.
Mexican President Andrés Manuel López Obrador, who claims to have good relations with both Trump and Biden, gives a similar reason.
During a press conference on Monday, the president said he will not congratulate Biden until all court proceedings are complete.
Called Chinese leader "villain"
That it would be quiet from the Chinese side is no surprise.
Chinese President Xi Jinping has not commented on the election at all and is not expected to do so soon.
"The outcome should be determined by law and regulations," Foreign Ministry spokesman Wang Wenbin said in a statement on Monday.
Whether Biden will be able to thaw the frosty relations between the countries remains to be seen.
It is clear, however, that it will be a challenge, not least after Biden called the Chinese leader a "villain" during the election campaign.
North Korea has called Biden a "crazy dog"
Another challenge awaiting incoming President Joe Biden is spelled Kim Jong-un.
North Korean state media have described Biden as a "crazy dog" who should be killed and his victory has not been mentioned in the report, writes TT.
