LONDON

The British prime minister said she urged the U.S. president to re-join the Paris Agreement on global climate change.

Theresa May spoke Saturday about subjects covered at the G20 including counterterrorism and climate change.

"Like other world leaders here, I am dismayed at the U.S. decision to pull out of the Paris Agreement and I have urged President [Donald] Trump to re-join it," May told reporters.

"The U.K.’s own commitment to the Paris Agreement and tackling global climate change is as strong as ever. Not only will this protect the environment for future generations, it will keep energy affordable and maintain a secure and reliable supply in order to protect the interests of businesses and consumers."

About the global terror threat and counterterrorism efforts, May said the G20 leaders "have agreed to take action in two specific areas: we need to ensure there are no safe spaces for terrorist financing by increasing capacity-building and raising standards worldwide, especially in terrorist finance hotspots."

"And we will develop tools to better identify suspicious small flows of money being used to support terrorist activity."

"I have also called for the G20 to come together to better manage the risk posed by foreign fighters as they disperse from the battlefield in Syria and Iraq, by improving international information-sharing on the movement of individuals known to have travelled to Daesh territory."

Disagreements between the U.S. administration and European governments on climate change led to tensions at a G7 summit in Italy two months ago.

While six of the world’s largest economies pledged commitment to the Paris climate deal, U.S. President Donald Trump did not join the consensus, pulling his country out of the agreement a week later.

The Paris Agreement, spearheaded by Trump's predecessor, Barack Obama, and signed by 195 countries in April 2016, aims to mitigate the effects of climate change by reducing carbon emissions and limiting global temperature rise to below 2 degrees Celsius.
