The world greeted a new American president Friday: Donald J. Trump.

"Congrats to my friend President Trump. Look fwd to working closely with you to make the alliance between Israel&USA stronger than ever," Israeli Prime Minister Benjamin Netanyahu tweeted Friday before Trump's address in Washington. Trump's ascension to the White House is expected by many to bolster the Israeli right.

The government of Egypt, traditionally a power broker in the Middle East and seen as seeking to regain its past status, also congratulated Trump before the speech. It has been reported that Sisi was the first Middle Eastern leader send Trump warm wishes.

"The Arab Republic of Egypt is looking to see Donald Trump's presidency pump new life into the course of Egyptian-American relations... promote peace and stability and development in the Middle East region, especially in the face of the huge challenges that it faces," a statement from Sisi read.

Sisi and Trump met at the United Nations in September; Trump praised Sisi as a "fantastic guy." Sisi has called on the international community to not "jump to conclusions" on the new president. And there have been reports that Trump, as president-elect, convinced Egypt to scuttle its support of a U.N. resolution critical of Israel; Trump heavily criticized the Obama administration for support that resolution.

"Congratulations @realDonaldTrump on assuming office as US President. Best wishes in leading USA to greater achievements in the coming years," Indian Prime Minister Narendra Modi tweeted. Trump's populist rise has been compared to Modi's, and some hardline Hindu nationalists have celebrated Trump's political victories. After winning the election in November, Trump complemented Modi.

Trump likewise received congratulations from Canada, the largest trading partner of the United States. Prime Minister Justin Trudeau said he looked forward to working with the new administration and noted the two countries' "robust trade and investment ties, and integrated economies" that "support millions of Canadian and American jobs."

Barack Obama held his last foreign call as president with Germany's Angela Merkel, it was reported Thursday. Obama is said to have believed it was "fitting" his final call would be to her. The White House in a statement hailed Germany's commitment to "ensuring a sturdy trans-Atlantic bond, a rules-based international order, and the defense of values that have done so much to advance human progress."

With Trump entering the White House, some commentators have commented that Merkel, running for a fourth term, may be the "liberal West's last defender."

The foreign minister of Mexico, a country whose leadership has been the subject of much Trump criticism, said he expects President Enrique Pena Nieto and Trump will talk directly in the coming days or weeks following high-level bilateral meetings in Washington next week.
