U.S. President Joe Biden will host British Prime Minister Rishi Sunak for talks at the White House Thursday that are expected to cover economic ties and supporting Ukraine in its defense against a Russian invasion.

The visit by Sunak is his first to the United States since becoming prime minister in October, but he and Biden have already met three times this year.

“The two leaders will review a range of global issues, including our economic partnership, our shared support for Ukraine as it defends itself against Russia’s brutal war of aggression, as well as further action to accelerate the clean energy transition,” White House press secretary Karine Jean-Pierre told reporters Wednesday. “The president and the prime minister will also discuss the joint U.S.-U.K. leadership on critical and emerging technologies as well as our work to strengthen our economic security. They will also review developments in Northern Ireland as part of their shared commitment to preserving the gains of the Belfast/Good Friday Agreement.”

Ahead of Thursday’s talks, Sunak said he would push for closer economic relations in the same spirit as the countries’ defense and security cooperation.

“Just as interoperability between our militaries has given us a battlefield advantage over our adversaries, greater economic interoperability will give us a crucial edge in the decades ahead,” Sunak said.

British officials said Sunak also wanted to discuss ways to protect global supply chains, particularly against individual countries that may corner and manipulate markets for certain sectors.

Another topic on the agenda for Sunak is the regulation of the burgeoning field of artificial intelligence.

Before meeting with Biden, Sunak held talks with congressional leaders and took part in a wreath-laying at Arlington National Cemetery. He also appeared at the Washington Nationals baseball game where the team was honoring U.S.-U.K. Friendship Day.
