The source argues that Elbridge Colby’s late-January 2026 visits to South Korea and Japan were designed to operationalize the Pentagon’s new deterrence-by-denial approach along the First Island Chain through greater allied burden-sharing and interoperability. It suggests that while trilateral mechanisms are maturing, political ambiguity—especially around Taiwan—could slow decision-making and weaken cohesion in a fast-moving crisis.
Japan and the Philippines are expanding defense cooperation through the RAA, OSA, and ACSA, enabling more regular and scalable joint operations along the First Island Chain. The source suggests this is stitching together the East China Sea and South China Sea into a more connected theater, complicating China’s ability to manage maritime tensions as separate fronts.
CSIS open-source analysis indicates China increased military and maritime operational tempo across the Indo-Pacific in 2025, with record activity around Taiwan and heightened South China Sea operations. The report also highlights expanded far-seas training and carrier operations beyond the First Island Chain, alongside fewer but qualitatively notable China-Russia joint exercises.
A large PLA exercise on Dec. 29–30, 2025 simulated blockade and amphibious seizure operations near Taiwan while China Coast Guard activity tested gray-zone thresholds. The episode sharpened U.S. congressional focus on accelerating arms transfers, but delivery backlogs and Taiwan’s domestic budget politics may constrain near-term deterrence.
Open-source reporting indicates China increased PLA and maritime activity across the Indo-Pacific in 2025, with record pressure around Taiwan and heightened operations in the South China Sea. The same reporting highlights expanded far-seas carrier operations beyond the First Island Chain and fewer—but more novel—China-Russia joint exercises.
