Putin hopes Biden less impulsive than Trump
"It is my great hope that, yes, there are some advantages, some disadvantages, but there will not be any impulse-based movements on behalf of the sitting US president," he said, according to a translation by NBC News.
"I believe that former US president Trump is an extraordinary individual, talented individual... He is a colorful individual. You may like him or not. But he didn't come from the US establishment," Putin was quoted as saying.
Biden plans to raise a range of US complaints, including over purported Russian election interference and hacking, in the summit with Putin on Wednesday in Geneva at the end of the new president's first foreign trip.
Putin has openly admitted that in the 2016 vote he supported Trump, who had voiced admiration for the Russian leader. At their first summit, Trump infamously appeared to accept Putin's denials of election interference.
Asked directly if he is "a killer," Putin chuckled but did not give a yes or no answer.
"Over my tenure, I've gotten used to attacks from all kinds of angles and from all kinds of areas under all kinds of pretext and reasons and of different caliber and fierceness, and none of it surprises me," he said, adding that the term "killer" was a "macho" term common in Hollywood.
Such discourse "is part of US political culture where it's considered normal. By the way, not here, it is not considered normal here," he said.
"At the very least, I don't know anything about this kind of thing," the Russian leader said, speaking from the Kremlin. "It's just nonsense garbage."
