MOSCOW (REUTERS) - Russian President Vladimir Putin will deliver a speech on Thursday (April 22) at an online climate change summit hosted by US President Joe Biden, the Kremlin said, despite a deep crisis in relations between Moscow and Washington.

Putin's attendance signals he is still open to dialogue with the United States even though the two countries have imposed new sanctions on each other in the past few days. He has yet to accept or decline a separate invitation from Biden to a bilateral summit.
