Yoon asked to focus on key economic issues at summit with Biden

"The joint statement from their (Yoon-Biden) May 2022 summit mentions that Biden welcomes Yoon's interest in the Quad but it will be interesting to see whether the conversation has progressed," Fitt said, adding he expects the upcoming summit will present a unified message on North Korea, South Korea-Japan rapprochement, rules-based order in the Indo-Pacific and other critical alliance synergies.

Both Cooper and Fitt stressed the document issue will have a minimal effect on the Yoon-Biden summit as it has been reported that the two sides have already engaged in considerable discussion on the topic.

"I do think the document issue will be an irritant, but mostly behind closed doors rather than in public," Cooper said. "Since the scope of the U.S.-South Korea is so vast and state visit agendas are so tight, any time spent talking about the leaks takes away from more important, forward-looking topics. Similarly, Biden did not discuss them when meeting with Prime Minister Rishi Sunak in Belfast," Fitt said.
