Biden and Sunak vow support for Ukraine, seek closer economic ties

Sunak is visiting the White House to improve UK-US relations and push for the UK to play a larger role in regulating AI and supporting Ukraine against Russian aggression.
Biden and Sunak signed the Atlantic Declaration to strengthen economic cooperation on clean energy, critical minerals, and emerging technologies like AI in the face of China's growth.
Ukraine will dominate the talks, and the US and UK aim to step up military aid as Ukraine launches a counteroffensive against Russian forces occupying parts of eastern Ukraine.
Sunak will lobby Biden to back UK Defense Secretary Ben Wallace to replace NATO's secretary general Jens Stoltenberg when he steps down in September.
Biden praised the UK as the US's closest ally but accidentally called Sunak "Mr. President" during their joint press conference, quickly correcting himself.
