Reinvesting in US-Japan-South Korea strategic relations

A new report from a trilateral working group outlines a path forward.

Analysis | Asia-Pacific

As foreign policy experts in the United States, Japan, and South Korea, the three of us recently participated in the U.S.-Japan-Republic of Korea Trilateral Alliance Working Group, organized by the National Committee on American Foreign Policy. Ten “next generation” scholars and practitioners from the United States, Japan, and South Korea were selected, representing academia, think tanks, and government, culminating in a report published today today entitled, “Reinvesting in U.S.-Japan-Republic of Korea Strategic Relations: A Practical Trilateral Agenda.” 

The NCAFP report lays out a vision for trilateral partnership that advances common interests rather than pursuing trilateralism as an objective in and of itself. The report offers ways to adopt a “whole-of-government” approach to alliance management by broadening areas of cooperation to nontraditional security threats such as pandemics and climate change. It also explores new areas of cooperation such as humanitarian assistance for North Korea that could provide critical need during this period of COVID-19 pandemic.

The three of us served in a subgroup focused on identifying domestic constraints that have historically prevented closer cooperation between the three countries and recommendations for how to overcome them.

First, we recognized that COVID-19 pandemic recovery will be top priority for Washington, Tokyo, and Seoul, but especially for Washington given the high COVID-19 infection rate in the United States.

On foreign policy, President Biden has pledged to renew alliances to address regional challenges, which is welcome and needed. But this will not be easy, even without COVID recovery taking most of this bandwidth for the time being.

The biggest constraint that the Biden administration will face is the growing tendency among hawks in Washington who exaggerate China’s threat, which could reduce the room to tackle urgent challenges such as climate crisis and global pandemics. The United States must resist  calls to frame U.S.-Japan-ROK strategic cooperation as part of a China containment strategy, and instead pursue a strategy based on cooperation, humility, and pragmatism.

In Japan, the biggest domestic constraint in forging more productive trilateral relations is the low public opinion toward South Korea. There is broad consensus among foreign policy and national security experts in Japan that trilateral cooperation would be mutually beneficial. Unfortunately, disagreement over historical issues has generated negative feelings about South Korea within the Japanese public, reaching a 41-year low.

The recent ruling by Seoul Central District Court concerning a group of former “comfort women” will likely exacerbate this negative trend within the Japanese public. Adding to this legal decision is the domestic political environment; the conservative Liberal Democratic Party is vying to maintain power in the upcoming elections. So it seems unlikely for Tokyo to proactively jumpstart bilateral relations with South Korea, thereby limiting the prospect for dramatic transformation in trilateral relations. 

Similarly, the biggest barrier toward improving trilateral cooperation on the part of South Korea is in building positive relations with Japan, which colonized South Korea from 1910 to 1945. Bipartisan public hostility toward Japan stems from unresolved historical issues such as comfort women and forced labor to more recent events, such as Japan's export restrictions against South Korea in 2019. Meanwhile, the Moon Jae-in administration has signaled interest in trilateral coordination to advance the peace process on the Korean Peninsula and respond to North Korea's missile and nuclear threats. 

So how do we move forward? One way is to resuscitate ideas from the 2017 trilateral vice foreign ministerial meeting between then-Deputy Secretary of State Anthony Blinken, Vice Minister for Foreign Affairs of Japan Shinsuke Sugiyama, and First Vice Minister of Foreign Affairs of South Korea Lim Sung-nam, such as trilateral cooperation on women’s empowerment, space policy, and humanitarian assistance. 

The business community and environmental groups could also collaborate more closely, identifying low-hanging fruit that advances domestic priorities and reinforces shared values of the three countries. 

Civil society, including cultural organizations, among the three democracies should also play a bigger role in building goodwill and trust over the long-term. Such efforts will likely improve public opinion more so than government-to-government cooperation given their visibility. 

Finally, more track-II efforts such as the NCAFP Trilateral Alliance Working Group are needed to build connective tissues between current and future policymakers in our countries.

As next generational leaders, we look forward to being part of future efforts that strengthen cooperation between our three countries. At a time when transnational threats show how small the world can be, the time is now for policymakers on both sides of the Pacific to challenge old assumptions and reimagine what is possible.

President Donald Trump’s second term has so far been a series of “shock and awe” campaigns both at home and abroad. But so far has left North Korea untouched even as it arms for the future.

The president dramatically broke with precedent during his first term, holding two summits as well as a brief meeting at the Demilitarized Zone with the North’s Supreme Leader Kim Jong-un. Unfortunately, engagement crashed and burned in Hanoi. The DPRK then pulled back, essentially severing contact with both the U.S. and South Korea.

Why new CENTCOM chief Brad Cooper is as wrong as the old one

Middle East

If accounts of President Donald Trump’s decision to strike Iranian nuclear facilities this past month are to be believed, the president’s initial impulse to stay out of the Israel-Iran conflict failed to survive the prodding of hawkish advisers, chiefly U.S. Central Command (CENTCOM) chief Michael Kurilla.

With Kurilla, an Iran hawk and staunch ally of both the Israeli government and erstwhile national security adviser Mike Waltz, set to leave office this summer, advocates of a more restrained foreign policy may understandably feel like they are out of the woods.

How Trump's 50-day deadline threat against Putin will backfire

Europe

In the first six months of his second term, President Donald Trump has demonstrated his love for three things: deals, tariffs, and ultimatums.

He got to combine these passions during his Oval Office meeting with NATO Secretary General Mark Rutte on Monday. Only moments after the two leaders announced a new plan to get military aid to Ukraine, Trump issued an ominous 50-day deadline for Russian President Vladimir Putin to agree to a ceasefire. “We're going to be doing secondary tariffs if we don't have a deal within 50 days,” Trump told the assembled reporters.
