SINGAPORE - During his visit to Hue, Vietnam’s former royal capital, earlier this year, Emperor Akihito and his entourage were reminded of their country’s long-standing cultural connections with Vietnam. In the eighth century, Phat Triet, a Cham Buddhist monk from what is now central Vietnam, traveled to Japan, where he helped to popularize Cham music and dance, which was later incorporated into the Japanese Imperial Court’s gagaku performances. During his visit, the Emperor had the opportunity to enjoy the Vietnamese version of gagaku, which also has Cham origins.
Emperor Akihito’s visit to Vietnam — the first by a Japanese monarch — represents an important milestone in the maturing bilateral relationship, which has been buttressed not only by strong cultural links, but also by robust economic ties and growing strategic cooperation. At the end of last year, Japan was Vietnam’s largest source of official development assistance, its second-largest foreign investor and its fourth-largest trade partner.
Along with closer economic cooperation in recent years, Japan and Vietnam have been strengthening strategic ties. The bilateral “strategic partnership” that was established in 2009 was upgraded to an “extended strategic partnership” in 2014.
Defense cooperation, in particular, has progressed considerably. In 2011, Japan and Vietnam signed a Memorandum of Understanding to deepen defense ties, which now include exchanges of military delegations, naval goodwill visits, an annual defense-policy dialogue, and cooperation in military aviation and air defense.
Much of this collaboration has centered on the South China Sea, where China’s increasingly powerful navy has been asserting its sovereignty claims with increasing vigor in recent years. For example, China unilaterally established an Air Defense Identification Zone in the East China Sea and constructed seven artificial islands in the disputed Spratly archipelago, located off the coast of southern Vietnam.
In late July, China reportedly threatened to attack Vietnamese bases in the Spratlys if Vietnam did not stop its oil exploration activities in an area that lies within Vietnam’s continental shelf, but also within Beijing’s notorious nine-dash line. Given the 2016 arbitral tribunal ruling that China’s maritime claims based on that nine-dash line are invalid, Vietnam has superior claims to the area. But Vietnam decided to back down, rather than face the risk of armed confrontation.
That does not, however, mean that China’s coercive actions — which not only undermine Vietnam’s own security, but also threaten the regional status quo — are not being met with resistance. In 2013, Japan’s then-defense minister, Itsunori Onodera, visited Vietnam’s Fourth Navy Zone headquarters in Cam Ranh Bay to observe Vietnam’s defense setup for the Spratlys. During that visit, Japan and Vietnam agreed to expand defense cooperation into new areas, especially modernization of Vietnam’s maritime defense agencies and military technology.
At Vietnam’s request, Japan has also provided the country with six patrol boats to support its defense activities in the South China Sea. Prime Minister Shinzo Abe, visiting Vietnam in January, pledged to provide six more boats worth $338 million.
Japan will also reportedly sell Vietnam two advanced radar-based earth observation satellites. The order, expected to be delivered by 2018 and funded by Japanese ODA, will enhance Vietnam’s maritime awareness in the South China Sea. Vietnam is also said to be considering a purchase of second-hand P-3C anti-submarine and maritime surveillance aircraft from Japan — a fleet that would likely be assigned to missions in the South China Sea.
From Vietnam’s perspective, Japan is perhaps the most important strategic partner with which to counterbalance China’s maritime expansionism and constrain its hegemonic ambitions. Japan is not only economically and militarily capable; it is also willing to help its Southeast Asian neighbors, so that they, too, can contribute to maintaining the regional balance of power. Japan’s power and long-standing antagonistic relationship with China reinforces the credibility of Japanese security commitments toward Vietnam and other countries in the region.
Vietnam’s interest in defense cooperation with Japan dovetails with the Abe administration’s goal of “normalizing” Japan’s defense posture, in order to reduce the country’s dependence on the United States. Japan considers Vietnam a particularly promising security partner, precisely because of the countries’ shared maritime security interests.
Now that U.S. President Donald Trump’s administration is threatening to reduce military engagement with Asia, the need for strategic cooperation among regional actors is becoming even more acute. This goes beyond bilateral relationships, to include potentially the creation of a “principled security network,” as the administration of his predecessor, U.S. President Barack Obama, once proposed.
Such an arrangement would resemble what Anne-Marie Slaughter and Mira Rapp-Hooper have called “mesh networks,” which “are highly resilient, because no individual node is critical to the structure’s survival — even if one link breaks, the structure survives.” Japan’s enhanced security ties with Vietnam and other like-minded Asian countries (such as Australia, the Philippines, Singapore and India), may lead to the emergence of such a resilient network, which can serve as a vital hedge against declining U.S. commitment to the region.
Of course, significant challenges lie ahead. Historical animosities continue to cast a shadow over Japan’s relationships with some Asian countries. Vietnam recalls the dark days of occupation by Japan during World War II, when famine killed up to 2 million Vietnamese.
But Vietnam has largely overcome its grudge against Japan. In fact, Emperor Akihito’s meeting, during his recent visit, with relatives of Japanese soldiers who remained after WWII to start families with Vietnamese women, served as a symbol of bilateral reconciliation. The path toward ever-deeper economic and strategic cooperation, shaped by convergent national interests, now seems clearer than ever.
