Putin praises Biden's professionalism after summit

Speaking to university graduates by video link later on Thursday, Putin, 68, had only warm words for Biden, 78, in contrast to Russian state media which has sometimes portrayed the U.S. president as struggling to do his job both physically and mentally.

"He is focused. He understands what he wants to achieve and reaches it very skillfully," the Russian President said.

Biden and Putin agreed at their first summit on Wednesday (June 16) to hold talks on arms control and cybersecurity.

Putin, who was first to brief reporters, said the meeting had been constructive, without hostility, and had showed the leaders' desire to understand each other.

There were no invitations to Washington or Moscow.

Biden, speaking shortly afterwards, said there was "no substitute for face-to-face dialogue", and that he had told Putin his agenda was "not against Russia" but "for the American people."
