Putin's comments came after a host at the Forum mentioned some social media sites, including Twitter, banned former U.S. President Donald Trump from their platforms earlier this year.
On January 6, hundreds of supporters of former U.S. President Donald Trump stormed the Capitol, fighting with police, urging violence against lawmakers and delaying the formal certification of President Joe Biden's election victory.
The violence left five people dead including a Capitol Police officer.
Some social media companies proceeded to ban Trump from their platforms.
Twitter permanently suspended Trump’s account due to the risk of further incitement of violence following the storming of the U.S. Capitol.
