The G20 summit will easily pass into oblivion for its collective agenda, but it should long be remembered for its bilateral and trilateral summits and one that failed to occur between the leaders of Japan and South Korea. Xi Jinping conducted many meaningful meetings. Modi Narendra balanced two triangular agendas with the United States and Japan on one side and China and Russia on the other. Moon Jae-in followed his presence in Osaka with a summit in Seoul with Donald Trump ushering in the Trump-Kim Jong-un summit at the DMZ. Of course, as the host, Abe Shinzo pursued wide-ranging diplomacy, followed immediately by launching an unprecedented blockage of trade with South Korea. Above all, on display was Donald Trump’s pattern of hijacking international, multilateral gatherings for his personal agenda. The final week of June 2019 and the month of July should be noted for a far-reaching diplomatic transformation.
