Biden and Sunak strengthen economic ties, discuss critical minerals and clean energy.

President Joe Biden and British Prime Minister Rishi Sunak have pledged to support Ukraine against Russia's ongoing invasion and deepen cooperation on clean energy and emerging technologies like artificial intelligence. The two leaders agreed on a new "Atlantic Declaration" to strengthen cooperation between the US and the UK on clean energy transition, development of emerging technologies, and protecting technology critical to national security. The leaders' talks also covered China, economic security, and more. Sunak's visit comes as US and British intelligence officials are still trying to sort out blame for the breaching of a major dam in southern Ukraine.
