U.S. President Donald Trump linked the protests ravaging France with the Paris agreement in a tweet he posted on Saturday.
The 2015 Paris agreement set goals to phase out fossil fuel use this century, shift towards cleaner energies and help limit a rise in temperatures.
French riot police fired tear gas and clashed with "yellow vest" protesters in central Paris on Saturday during the latest in a wave of demonstrations against the high cost of living that have shaken President Emmanuel Macron's authority.
A police spokeswoman told reporters there were about 1,500 protesters on the Champs Elysees boulevard. Large groups of people spilled into other areas and heading to eastern Paris, where a march against climate change was scheduled for the afternoon. Some also temporarily blocked the ring road circling central Paris.
U.S. President Donald Trump said on Saturday investigators had found no evidence of collusion with Russia, a day after U.S. prosecutors detailed a previously unknown attempt by a Russian to help his 2016 presidential election campaign.
The alleged Russian approach was outlined in one of several court filings Friday by U.S. prosecutors in New York and Special Counsel Robert Mueller seeking prison time for Trump's former lawyer, Michael Cohen. He is to be sentenced next week for campaign finance violations, financial crimes and lying to Congress about Trump's business dealings in Russia.
During discussions about a possible hotel bearing Trump's name in Moscow, Cohen told prosecutors, he was approached in November 2015 by an unnamed Russian claiming to be a "'trusted person' in the Russian Federation," the filing said.
Mueller said that discussions about the potential Moscow development were relevant to his investigation because they occurred "at a time of sustained efforts by the Russian government to interfere with the U.S. presidential election."
In a separate federal court filing on Friday, Mueller's office said that Trump's former campaign chairman, Paul Manafort, lied to investigators about his interactions with a Russian tied to Russian intelligence services.
That filing detailed why Mueller's office last week retracted a plea agreement with Manafort. He pleaded guilty in September to two conspiracy charges and agreed to cooperate with investigators in hopes of a lighter sentence.
Mueller is investigating whether there was collusion between Trump's 2016 presidential campaign and Russia, which U.S. intelligence agencies charge mounted an influence operation to sway the vote to Trump over his Democratic rival, Hillary Clinton.
Russia denies interfering in the election to help Trump.
