'Critically important' to maintain Good Friday agreement: Biden

"We strongly support that, and think it's critically important to be maintained," Biden said at the start of a virtual meeting with Irish Prime Minister Micheál Martin on St. Patrick's Day. "The political and economic stability of Northern Ireland is very much in the interest of all our people."

Biden and Martin pledged to expand ties between the two close allies, including on issues such as climate change, combating the coronavirus pandemic, and cancer research.

Martin said he looked forward to visiting Washington and hoped Biden would be able to visit Ireland once it was safe.

The Irish leader thanked Biden for his "unwavering support" of the Good Friday Agreement, adding, "It has meant a lot. And it has mattered."
