China and the United States will sign a global climate pact on April 22 in a bid to compel other countries to formally join the agreement and advance steps to cut carbon emissions.
A joint statement from the two countries said “climate change has become a pillar of the US-China bilateral relationship”, the Wall Street Journal reported.
US President Barack Obama and Chinese leader Xi Jinping met at a summit in Washington on Thursday.
“Our hope is that as that process proceeds, you will see growing momentum toward having this agreement enter into force early and swiftly,” Brian Deese, a senior adviser to Obama, was quoted as saying.
“That will help build the critical momentum that we all saw coming out Paris.”
The climate deal, completed last year in Paris, was forged by more than 190 nations, but US-China cooperation was key to securing commitments from around the world.
In the US, legal challenges to the Obama administration’s plan to limit carbon emissions from power plants could hamper efforts to follow through on commitments in the Paris accord, the newspaper said.
The Supreme Court has temporarily blocked the power-plant regulation.
