Increased economic integration between Japan and South Korea makes so much sense:

South Korean President Yoon Suk Yeol and Japanese Prime Minister Fumio Kishida agreed Friday to work together to cut costs and establish international rules in the hydrogen sector.
During a discussion at Stanford University, the two leaders talked about ways their countries can cooperate in the hydrogen sector, given South Korea’s wide use of hydrogen cars and Japan’s large number of hydrogen-related patents.
Both Yoon and Kishida attended the Asia-Pacific Economic Cooperation (APEC) summit in San Francisco this week.
The discussion came a day after they held a bilateral meeting on the sidelines of the APEC summit, their seventh bilateral summit this year, as Seoul and Tokyo push to mend and develop their relationship after years of tensions over historical disputes.
