Sunak expressed his strong agreement, saying he hopes for close cooperation with South Korea in energy, including nuclear power, defense and semiconductors, according to Lee.

Sunak also called for deepening the two countries' ties as they mark the 140th anniversary of the beginning of exchanges this year, saying he plans to make South Korea the most important partner in the Asia-Pacific region and proposes crafting a detailed plan and agreement on South Korea-Britain cooperation at the earliest possible date.
