World leaders urged countries not to lose sight of climate goals in the coronavirus pandemic, endorsing the aims of the Paris agreement amid hopes that U.S. President-elect Joe Biden will rejoin the accord.

Participants on the second day of a virtual Group of 20 summit discussed climate change in a session hosted by Saudi Arabia, holder of the forum’s presidency. The U.S. formally exited the Paris accord, which pledges limits on fossil fuel pollution, earlier this month.

"G20 members should strengthen the fight against climate change, and continue to play a leading role to achieve full, effective implementation of the Paris agreement,” Chinese President Xi Jinping said.
