Paris and Washington are ready to continue providing political, security, humanitarian, and economic assistance to Ukraine for as long as takes, United States President Joe Biden and French President Emmanuel Macron said in a joint statement.

The two leaders at talks in Washington reaffirmed "their nations' continued support for Ukraine's defense of its sovereignty and territorial integrity, including the provision of political, security, humanitarian, and economic assistance to Ukraine for as long as it takes."

"This includes the provision of significant resources to support Ukrainian civilian resilience through the winter, including stepping up the delivery of air defense systems and equipment needed to repair Ukraine's energy grid," Biden and Macron said in a statement released by the White House on Thursday.

Macron is on an official visit to Washington on Thursday, where he is holding talks with Biden.
