German Chancellor Angela Merkel has said Pope Francis encouraged her to work to preserve the Paris climate accord despite the US withdrawal during a meeting at the Vatican.
Speaking after a 40-minute meeting in the Apostolic Palace, which focused on the G20 summit that Germany is hosting in Hamburg on July 7-8, she said the Pope also shared her aim to "bring down walls" and not build them.
The Vatican said the talks focused on the need for the international community to combat poverty, hunger, terrorism and climate change.
Ms Merkel told reporters she briefed the Pope on Germany's G20 agenda, which she said "assumes that we are a world in which we want to work together multilaterally, a world in which we don't want to build walls but bring down walls".
Francis has consistently called for nations to build bridges not walls - including in reference to the border wall the Trump administration wants to build with Mexico.
Ms Merkel said Francis encouraged her to fight for international agreements, including the 2015 Paris climate accord, which aims to curb heat-trapping emissions.
"We know that regrettably, the United States is leaving this accord," Ms Merkel said.
As he did when President Donald Trump visited last month, Francis gave Ms Merkel a copy of his environmental encyclical, Praise Be, which casts fighting climate change and caring for the environment as an urgent moral obligation.
Francis issued the encyclical in the run-up to the Paris negotiations in hope of urging a global consensus on the need to change the "perverse" development models which he said had enriched the wealthy at the expense of the poor and turned God's creation into an "immense pile of filth".
The audience began with Francis expressing his condolences over the death of former chancellor Helmut Kohl.
In his formal note of condolences, Francis called Mr Kohl a "great statesman and convinced European" who worked tirelessly for the unity of his homeland and the continent.
In a particularly heartfelt tone, Francis said he was praying that the Lord gives Mr Kohl "the gift of eternal joy and life in heaven".
