Japan’s Delicate Balancing Act in the South China Sea

Sino-Japanese relations have long been marred by a maritime and territorial row in the East China Sea as well as a historical dispute over Japan’s wartime memory, which has prevented sustainable rapprochement. Further complicating the situation, bilateral ties are now increasingly strained by Japan’s growing presence in the South China Sea, where overlapping territorial and maritime disputes have pitted China against several Southeast Asian neighbours.

At the recent Shangri-La Dialogue, Asia’s most important defense and security summit, Japanese defense minister Tomomi Inada delivered pointed criticisms of China, deploring its attempts to “upend the rules-based order” and “alter the status quo based on assertions incompatible with existing international norms.” While never directly referring to China, Inada’s remarks were some of the most vivid official expressions in recent years of Japan’s concerns regarding China’s foreign policy. The following day, Beijing issued a rebuttal, expressing its “strong dissatisfaction and firm opposition” to what it deemed “irresponsible remarks.”

The JS Izumo, the Japanese Maritime Self-Defense Force’s largest warship, is currently sailing through the South China Sea for three months, making port calls to Singapore, Indonesia, the Philippines and Sri Lanka. The cross-ocean trek comes just as the warship is preparing to take part in a multilateral naval exercise in the Indian Ocean in July, along with India and the United States. The Izumo’s itinerary is meant to serve as a sign of Japan’s commitment to its Southeast Asian partners and is a clear response to what it perceives as China’s overbearing approach to the South China Sea. Notably, the trip also comes on the heels of Tokyo’s November 2016 announcement of the so-called Vientiane Vision, which lays out Japan’s plans for increased defense cooperation with members of the Association of Southeast Asian Nations (ASEAN).

Despite not being a claimant in the South China Sea disputes, Japan is thus poised to become a major player in the body of water, which is likely to heighten tensions with Beijing. With already frayed ties due to the East China Sea’s Senkaku Islands dispute, which shows no sign of subsiding, one may wonder why Japan would risk escalation by increasing its visibility in an area that Beijing sees as vital to its national security.

While the sustained presence of military assets is a relatively new phenomenon, Japan has long been concerned with maritime safety and the security of sea lines of communication in the South China Sea, through which 90 percent of its oil imports transit. As a major maritime trading nation, Japan has seen maritime transport as critically important for national security, and successive Japanese governments since the 1960s have invested heavily in securing sea lines of communication. Japan has founded or given impetus to organizations or agreements whose aims were to enhance maritime safety, such as the Malacca Strait Council in 1968 and the Regional Cooperation Agreement on Combatting Piracy and Armed Robbery against Ships in Asia (ReCAAP) in 2001. Japan has also consistently brought up maritime security in multilateral settings such as the ASEAN Regional Forum, the East Asian Summit and the ASEAN Defense Ministers Meeting Plus.

However, more recently, the main driver of Japan’s involvement in the South China Sea has been the territorial disputes with China and the latter’s growing assertiveness in the maritime domain. Tokyo sees strong normative parallels between Beijing’s approaches to the South and East China Seas, leading to worries that Chinese gains in one area could embolden it in the other. In 2013, former Japanese defense minister Itsunori Onodera explicitly made the connection between the two locales, stating that “the Japan side (was) very concerned that this kind of situation in the South China Sea could affect the situation in the East China Sea.” Since that point, the Abe administration has consistently prioritized the South China Sea issue and has spent significant investment and political capital in strengthening its commitment to the other littoral states in ASEAN.
