Mr. Trump told reporters while visiting the devastated areas in California that the us needs to improve fire management.
President Trump has been criticized by experts over his claim that "raking and cleaning" forest floors could help prevent future fires from spreading.
Like their president, ordinary Finns were baffled by Trump's comments and quickly took to social media to mock the USA president with photos and videos accompanied by hashtags like #RakeFinlandGreatAgain and #RakeNews. "You know the floors of the forest, very important", Trump said.
They also have no idea how the small population could rake vast swathes of forest.
"While Finland's leader was bemused, Finns themselves were amused, especially with the hashtag "#haravointi", Finnish for "raking". This is significant, given Donald Trump's own, starkly different, response to the tragedy now affecting thousands on the United States' west coast.
Finnish people have ridiculed Mr Trump's remarks, taking to Twitter to express their bafflement and amusement at the suggestion.
'We're going to have that, and we are going to have forests that are very safe because we can't go through this'.
While experts agree that tree clearing and other forest management work is necessary, the Trump administration has proposed slashing tens of millions of dollars from the Department of Interior and US Forest Service budgets.
Brown said: "I think over the next months and years you'll see the science becoming crystal clear and even the folks in Washington that are now more in the denialist [sic] camp are going to come around".
It wasn't until five tweets later, more than 12 hours after that initial angry screed, that he posted a more supportive message to his social feeds.
The death toll far surpasses the previous fatality record from a single California wildfire - 29 in the Griffith Park fire of 1933 in Los Angeles - and already ranks among the deadliest US wildfires since the turn of the last century.
Meanwhile Yrjo Niskanen, head of emergency preparedness at Finland's national forest center, said the U.S. president may have been referring to the practice of removing branches and loose material left in the forest after logging.
