Canada-U.S. relations seem to have reached their lowest point in more than a generation after Trump tweeted Saturday that he was withdrawing support from a G7 joint communique, while complaining he had been blindsided by Trudeau's criticism of U.S. tariffs at a closing news conference.
"There are always irritants in relationships", Pompeo said while in Singapore for a summit between Trump and North Korea's Kim Jong Un.
Trump on Saturday said the US would not sign the G-7 communique, and USA officials suggested Trudeau had double-crossed the president by saying one thing in private and another publicly.
German Chancellor Angela Merkel, speaking Sunday to German public television, said she found Trump's tweet disavowing the G-7 statement "sobering" and "a little depressing".

Mr Trump has consistently said that countries that have a trade surplus with the United States - meaning they export more to the USA than they import - are "taking advantage" of the US.
Trump also renewed attacks on Canadian Prime Minister Justin Trudeau, who had hosted the G7 meeting in Quebec.
Ms. May ducked Mr. Corbyn's question and when later asked by Conservative MP Crispin Blunt: "Trudeau or Trump?", she smiled and replied: "I'm not sure what activity he's asking me to undertake with either of them".
The tit-for-tat dispute over US metals tariffs followed more than a year of tense and so far unsuccessful negotiations to renew NAFTA and a long and failed charm offensive by Trudeau and top Canadian officials to avoid Trump's trade ire.
British Prime Minister Theresa May said on Monday that a meeting of the Group of Seven leaders in Canada had been "difficult" and that countries had to avoid taking unilateral action in order to protect the global trading system.More news: Dele Alli promises best behaviour at World Cup
Following Trudeau's statement during the news conference, Trump posted two tweets slamming his words as "false" and accused the Canadian prime minister of being dishonest. "Using that type of language is not professional, it's not called for, and I tell you, I was deeply disappointed to see this lack of professionalism on his part". May pointed out the importance of maintaining a dialogue with the United States and President Trump.
Sen. John McCain (R-Ariz.) on Twitter Saturday sought to counter the comments about Trudeau.
Trudeau had said Canadians "are polite, we're reasonable, but also we will not be pushed around". Those tariffs will come into place July 1 if the US doesn't remove their tariffs before that date.
He also suggested something more nefarious may have been afoot when Navarro made the comments.

"He is an unprecedented president and he's outside of all of the normal boundaries of behaviour for an American president". "This, I've never seen before". He tweeted hours later that he had instructed US representatives not to endorse the G7 joint communique "based on Justin's false statements at his news conference, and the fact that Canada is charging massive Tariffs to our USA farmers, workers and companies". "On the contrary, as part of the USA law, we are part of the national defense base of the United States".
