On Wednesday, British Prime Minister Rishi Sunak and South Korean President Yoon Suk Yeol will hold talks and sign a deal enhancing collaboration in the areas of technology, security, and defense.

While in London on a state visit, Yoon and Sunak will sign a Downing Street Accord that calls for their joint enforcement of UN sanctions on North Korea’s isolationist regime.

Ministers have agreed to a partnership on clean energy and are beginning negotiations on a new free trade agreement (FTA). A number of investments have also been announced, including plans for $1.16 billion worth of wind farm projects in South Korea from BP PLC (BP.L) and offshore wind company Corio Generation.

A conservative, Yoon has cited a “polycrisis” of global challenges as a reason for seeking closer ties with like-minded partners, and welcomed talks to update the FTA, which is currently based on a 2011 deal with the European Union.

“During the negotiations, we will actively seek the views of business leaders from both countries, and set new norms on digital, supply chains and energy to create a level playing field,” Yoon said in translated remarks to a business forum.
