China steps up targeted pressure on Japan amid Taiwan tensions

April 21 (Asia Today) -- China is intensifying a targeted pressure campaign against Japan as tensions rise across the Taiwan Strait and the East China Sea, with signs of potential physical confrontation emerging beyond diplomatic disputes.

Analysts say Beijing is adopting a more focused strategy aimed at Japan rather than the United States, while Tokyo is expanding its military posture under Prime Minister Sanae Takaichi's administration, raising the risk of direct confrontation between the two regional powers.

Tensions escalated Friday when the Japanese Maritime Self-Defense Force destroyer Ikazuchi transited the Taiwan Strait, officially en route to participate in the Balikatan 2026 joint exercises in the Philippines.

China responded unusually forcefully. The Eastern Theater Command of the People's Liberation Army deployed J-20 stealth fighters and CH-4 attack drones to closely track the vessel and released the footage through state broadcaster China Central Television.

Military sources cited by Chinese state-linked platforms said Beijing is shifting from diplomatic protests against U.S. naval passages to demonstrating real-time "targeting within strike range" against Japanese vessels, signaling a more direct military warning.

The move is widely interpreted as a preemptive warning against Japan's stated willingness to intervene in a Taiwan contingency.

China's pressure has also expanded beyond military signaling.

Near the disputed Senkaku Islands, Chinese coast guard ships have increased patrols, while Beijing has moved ahead with installing a 23rd offshore structure near the median line in the East China Sea. Experts say the facility could function as a forward monitoring outpost tracking Japanese Self-Defense Forces movements.

At the same time, China is combining economic pressure with security measures. Export restrictions announced earlier this year on dual-use materials - including rare earth elements and specialty alloys essential for advanced missile defense systems - are seen as targeting vulnerabilities in Japan's defense supply chain.

Japan has responded by strengthening its military role. It has deployed about 1,400 troops - including combat units - to the Balikatan exercises, marking its largest-ever participation and its first full-scale deployment of such forces.

The deployment includes warships, aircraft and Type 88 anti-ship missile units positioned in northern Luzon, with plans for live-fire drills extending toward the South China Sea. Analysts say this reflects Tokyo's effort to operationalize its "counterstrike capability" beyond its territory.

Japan is also accelerating efforts to fortify its southwestern island chain, including deploying medium-range surface-to-air missile units on Yonaguni Island, placing parts of mainland China within operational range.

In response, China dispatched a naval task force led by a Type 052D guided-missile destroyer, known as China's version of the Aegis system, into waters near Japan's southwestern islands, including key maritime routes such as the Yokoate Channel.

Chinese officials issued strong warnings, accusing Japan of reviving militarism and staging a show of force near what analysts describe as Japan's strategic vulnerabilities.

Security experts say China's focus on Japan reflects a calculated strategy to test the U.S.-Japan alliance indirectly, avoiding direct confrontation with Washington while applying pressure on what it views as a weaker link.

"The intention is to stir domestic concerns in Japan over economic damage and weaken support for its security policy," said Joo Eun-sik, head of a South Korean security think tank and a retired brigadier general.

Analysts warn that the escalating confrontation represents not a temporary dispute but a broader restructuring of the regional security order, with implications for South Korea's defense posture and supply chains.

They say the combination of military pressure and economic measures underscores the need for Seoul to prepare for complex risks where security tensions spill over into trade and industrial vulnerabilities.
