Japan test‑fired a Tomahawk cruise missile from the destroyer Chokai on July 29, a weapon with a 1,600 km range that can reach PRC territory when launched from a ship near Japan, and announced plans to acquire 400 of the missiles. Japan’s 2026 Defense White Paper, released August 4, identified PRC short‑of‑war coercion as a major threat and described frequent combined PRC‑Russia deployments and flights near Japanese territory as demonstrations of force. PRC Ministry of Defense spokesperson Chen Xi criticized the white paper on August 4, saying it exaggerated the threat and that Japan was using the PRC as a pretext for remilitarization. Japan’s Defense Minister Shinjiro Koizumi said the white paper was intended for civilian readers. The PLA Navy’s Type 076 amphibious assault vessel Sichuan, with a displacement over 50,000 tons, was reported by state broadcaster CCTV to be capable of operating manned aircraft and to function as a quasi‑aircraft carrier, a capability that could supplement the PLAN’s limited carrier aviation. ISW‑CDOT analysis notes that the vessel’s single electromagnetic catapult limits its sortie rate and that it can launch large drones to support older carriers that lack catapults. In the South China Sea, the Philippines filed a nautical chart with the UN on July 31 detailing its claimed territorial baseline around Scarborough Shoal, invoking UNCLOS and a 2016 arbitration decision. The PRC embassy in Manila warned the Philippines to respect PRC sovereignty, and the CCG conducted a law‑enforcement drill around the shoal on August 1 involving boarding and seizure exercises. PRC state media described the drills as part of a broader toolbox of countermeasures against Philippine actions. PRC fishing and cargo vessels have been linked to undersea cable sabotage; a PRC‑flagged research vessel, likely Shiyan 1, loitered over the Pacific Light Cable Network from July 28 to August 2, raising concerns about potential disruption of Taiwan’s internet infrastructure. Taiwan increased its military recruitment to 17,113 personnel in 2025, exceeding its target, and its retention rate rose to 87.2 percent, according to the Ministry of National Defense. Taiwan’s Supreme Court classified the CCP and Taiwan Affairs Office as foreign hostile forces under the Anti‑Infiltration Act, a ruling that was upheld on July 29. The United States and Taiwan publicized their first combined Coast Guard patrol in Taiwanese waters on July 28, following a 2021 memorandum of understanding to improve maritime security cooperation. PLA aircraft conducted 190 incursions into Taiwan’s Air Defense Identification Zone in July, a decline from earlier peaks and suggesting a possible shift in PRC coercion strategy. Japan’s test‑fire and procurement of Tomahawks, together with its white paper emphasis on PRC coercion, indicate that Japan views PRC pressure as ineffective, while the PLAN may employ the Type 076 vessel to expand its carrier‑based aviation capability despite operational constraints. These developments illustrate a multi‑theater security environment in which defense modernization, territorial disputes, and undersea infrastructure vulnerabilities intersect.
