On Wednesday, Trump criticized Germany for being what he called a captive of Russian energy.
"When it comes to Nord Stream, Canada has significant concerns about that project", she said.
An unidentified spokesperson for the US State Department told Reuters that the project would "undermine Europe's overall energy security and stability" by providing Russian Federation a tool for the political coercion of European countries, especially Ukraine.
Donald Trump is "applying political pressure" over Nord Stream 2, a planned gas link from Russian Federation to Germany which is opposed by the United States government, a senior Polish official said on Friday.
"I have to say, I think it's very sad when Germany makes a massive oil and gas deal with Russia, where you're supposed to be guarding against Russia, and Germany goes out and pays billions and billions of dollars a year to Russia".
When Russia took over the Crimea and moved on eastern Ukraine in 2014, the United States and its allies slapped sanctions on Russia that have chafed Russian President Vladimir Putin ever since.More news: Samsung Galaxy S10+ Rumored To Have Five Cameras, Specs and Price
Canadian Foreign Affairs Minister Chrystia Freeland was more diplomatic than Trump, but the same message was directed toward Germany.
This sensitive matter [on the Nord Stream 2 gas pipeline] has been discussed in the European Union for some time. I think that in this context this is the most urgent: we need to ensure that transit through Ukraine continues, vice-president of the EC said. In Department believe that the pipeline would undermine energy security and stability of Europe.
"They will use that to weaken the European Union, to divide the European allies", Shevchenko said in an interview.
Freeland has been a vocal opponent of Russian meddling in the affairs of democratic countries.
Former Secretary of State John Kerry also condemned Trump, saying in a Twitter message that Trump's remarks about Germany and North Atlantic Treaty Organisation were "disgraceful, destructive and flies in the face of the actual interest of the United States of America".
German Chancellor Angela Merkel - who grew up behind the Iron Curtain in communist East Germany - shot back at Trump.
