Japan's PM Promises an 'Firm' Answer Following Targeting Altercation Involving Chinese Aircraft.

Japan's prime minister, Sanae Takaichi, has pledged to act "in a composed yet firm manner" after claims that People's Liberation Army aircraft locked their radar onto Japan's F-15s south-east of the main island over the past weekend.

A Concerning Incident Disclosed

According to Japan's defence ministry, China's J-15 jets from the aircraft carrier Liaoning activated its targeting radar on Japanese F-15s twice last Saturday. The first incident took place at 4:32 p.m. and was repeated approximately later. Officials stated that visual confirmation could not be obtained because of the distance, adding that no damage or injuries resulted.

"It marked an unprecedented instance Japan's defence ministry has reported such an incident," a report stated. Military aircraft commonly use radar for target identification.

Official Protest and Denials

Reacting to Tokyo's claims, China's military released a statement dismissing them as "completely inconsistent with reality." It urged Tokyo to "immediately stop making false accusations." Conversely, China asserted that Japan's SDF planes had "seriously endangered flight safety" by consistently approaching its training zones. Beijing did not mention a radar lock-on.

An official for the Chinese Ministry of Foreign Affairs later called on Tokyo to "halt its dangerous moves of harassing our routine military exercise and training."

Escalating Strains and Regional Context

Ties between China and Tokyo have worsened markedly in recent weeks. The downturn followed PM Takaichi stated that an attack on Taiwan could trigger the deployment of Japanese Self-Defense Forces if such a conflict posed an existential threat to Japan.

She argued that Japan could exercise its right to collective defense, which involves assisting a partner under attack. She stated that Japan had to "anticipate the most severe possibilities" in the Taiwan Strait.

The Japanese defence minister, Shinjiro Koizumi, labeled Saturday's encounter as "highly risky and deeply unfortunate." In a diplomatic move, China's envoy to Japan, Wu Jianghao, was called in on Sunday.

Japan's vice minister for foreign affairs, Funakoshi Takehiro, lodged a "strong protest" and demanded Beijing to "guarantee that such acts are not repeated."

Enduring Disputes

Japan and China are also locked in a protracted sovereignty disagreement over the islands, which are known as the Diaoyu by Beijing. These small, uninhabited islets lie in waters between Okinawa and Taiwan.

Additionally, broader geopolitical tensions persist. Japan is deepening military and strategic ties with American and other allies in the Indo-Pacific area, where a number of countries have their own maritime) disputes with China.

China, in turn, asserts vast sovereignty claims in adjacent seas, a posture that has prompted criticism and legal challenges.
