Security tensions in Northeast Asia are rising again after China and Japan faced off for about seven hours in waters near the disputed Senkaku Islands, known in China as the Diaoyu Islands. The standoff, which came shortly after China test-fired a submarine-launched ballistic missile (SLBM), reflects growing regional instability as the two countries' maritime sovereignty dispute becomes entangled with military and security issues.
According to the China Coast Guard and Japan's Regional Coast Guard Headquarters, two Chinese vessels entered Japanese territorial waters off Taisho Island, known in China as Chiwei, in the Senkaku Islands at 2:23 a.m. the previous day. The vessels approached a Japanese ship in the vicinity, and both were equipped with naval guns.
Jiji Press reported that "Japan's Regional Coast Guard Headquarters dispatched a patrol boat and demanded the Chinese vessels leave Japanese territorial waters." It added that "the vessels of the two countries continued the standoff for about seven hours before the situation ended around 9:20 a.m. as the Chinese vessels turned back."
The two sides did not engage in physical conflict but exchanged sharp words. Japan criticized "China's repeated intrusions into its territorial waters as acts undermining regional stability," while China urged that "the Diaoyu Islands and their affiliated islets are China's inherent territory, and Japan must stop its acts of sovereignty infringement and provocation in these waters."
The standoff occurred right after China test-fired an SLBM toward the Pacific on Saturday, heightening concerns in the Northeast Asian region. China explained that it was part of a routine military exercise, but Japan denounced the SLBM launch while focusing on China's expanding operation of strategic weapons and its intensifying maritime activities.
However, no direct link between China's SLBM test launch and the Senkaku standoff has been confirmed so far. Rather than interpreting the two events as cause and effect, experts in international relations analyze them as a series of escalating tensions arising from the convergence of China's military buildup and expanding maritime advances with Japan's heightened vigilance.
Located in the southwestern East China Sea, the Senkaku Islands consist of five uninhabited islands and three reefs. Japan holds effective control, but China and Taiwan each claim sovereignty, putting the three countries in a dispute. No one lives on the islands, which administratively belong to Ishigaki City in Japan's Okinawa Prefecture.
China and Japan have long been in conflict over sovereignty of the Senkaku Islands, with recurring frictions over the entry of coast guard vessels and fishing boats from both countries into nearby waters. In particular, when the Japanese government completed the nationalization of the Senkaku Islands in 2012, the conflict between the two countries reached its peak, with large-scale retaliatory measures in China including a boycott of Japanese products and a ban on rare earth exports.
