The upset defeat of former Secretary of State Hillary Clinton by real estate mogul Donald Trump to be the 45th president of the United States shocked many Americans, as well as world leaders.

But in foreign relations, diplomacy is crucial. Here are some of the congratulations sent to President-Elect Trump.


President Vladimir Putin congratulated Trump on his triumph Wednesday and said he hopes the two of them "can establish a constructive dialogue" and work together to resolve U.S.-Russian crisis relations and international security challenges, according to the Kremlin website.


Prime Minister Theresa May, despite her previous criticism of Trump's remarks, congratulated him on "a hard-fought campaign." She stated in a personal Facebook post that Britain and the United States have had a "special relationship based on the values of freedom, democracy and enterprise... and will remain, strong and close partners on trade, security and defence."


President François Hollande openly endorsed Hillary Clinton in the United States 2016 presidential election. When Trump was elected, Hollande congratulated him with little gusto. "Certain positions taken by Donald Trump during the American campaign must be confronted with the values and interests we share with the United States,? The Guardian reported.


President Xi Jinping called Trump to congratulate him on his victory,  according to Chinese state media.  "I place great importance on the China-U.S. relationship, and look forward to working with you to uphold the principles of non-conflict, non-confrontation, mutual respect and win-win cooperation," reports alleged that Xi said to Trump. He said he hopes to avoid conflict and find healthy, stable relations.


Prime Mister Narendra Modi addressed his views on a Trump Presidency via Twitter.


President Enrique Pena Nieto did not outwardly congratulate Donald Trump but instead hopes the U.S. and Mexico remain allies and show mutual respect.

According to the New York Times, former presidential candidate Andrés Manuel López Obrador, urged Mexicans to remain calm and, ?We will stay together no matter what the circumstances are.?


Prime Minister Justin Trudeau released a statement congratulating Trump. He stated, "Canada has no closer friend, partner, and ally than the United States."

The NYT reported that Trump's plan to revisit the North American Free Trade Agreement could cause uncertainty to Canada's economy and that Trudeau's approach to immigration is the exact opposite of Trumps which could cause more issues.
