Foreign leaders have pledged to work with Donald Trump.
However, some officials expressed alarm that the vote could mark the end of an era in which Washington promoted democratic values and is seen by its allies as a guarantor of peace.
Throughout his campaign, Trump described a dark America that has been knocked to its knees by China, Mexico, Russia and ISIL.
He has vowed to win economic concessions from China and to build a wall on the US border with Mexico to keep out illegal immigrants.
Canadian Prime Minister Justin Trudeau says he is looking forward to working with Donald Trump.
The left-leaning Trudeau, who supports free trade and higher immigration, is ideologically removed from the Republican US president-elect.
On the campaign trail, Trump vowed to revise or tear up the North American Free Trade Agreement (NAFTA), under which Canada sends 75% of its exports to the US.
Canadian officials must now work out how Canada’s export-reliant economy can maintain its privileged US access.
A November study by Export Development Canada said exports to the US could drop between 1.2% to 4.5%, depending on how radical an approach Trump takes.
The Trump win could also imperil Trudeau’s plan to impose a carbon price as part of a commitment to meet international climate change goals.
Trump has said global warming is a hoax.
During the campaign, Trump expressed admiration for Russian President Vladimir Putin.
russia and Putin appear to be winners from Trump’s victory. Defying years of US foreign policy orthodoxy, the Republican has promised much warmer relations with Moscow.
This is despite Russia’s intervention in the Syrian civil war and its annexation of Ukraine’s Crimea region.
Russia’s parliament erupted in applause after a lawmaker announced that Trump had been elected.
Putin told foreign ambassadors he is ready to fully restore ties with Washington.
“It is not an easy path but we are ready to do our part and do everything to return Russia and American relations to a stable path of development,” *Vladimir Putin*said.
Russia is hoping that improved relations could yield an elusive prize: the lifting or easing of sanctions imposed by the United States and European Union to punish Moscow for its involvement in Crimea and eastern Ukraine.
US neighbour Mexico has congratulated Trump on his win.
It is an uneasy relationship due to his contentious, pre-election comments about Mexicans.
“I spoke with the US president-elect Donald Trump a few hours ago to congratulate him on his win. I must say it was a warm, friendly and respectful conversation.”
Israeli Prime Minister Benjamin Netanyahu says he hopes to reach “new heights” in bilateral ties under Trump.
Chinese President Xi Jinping said Beijing and Washington shared responsibility for promoting global development and prosperity.
Iran urged Trump to stay committed to the nuclear accord between Tehran and world powers.
Several authoritarian and right-wing leaders hailed Trump’s victory.
Other officials denounced the Trump victory, calling it a worrying signal for liberal democracy and tolerance in the world.
