On April 20, 2026, China’s aircraft carrier Liaoning ventured into the Taiwan Strait and made its way to the South China Sea, showcasing a clear signal of military assertiveness. This deployment coincided with Japan’s destroyer JS Ikazuchi passing through the Taiwan Strait just days earlier, on April 17. That date is significant as it marks the anniversary of the 1895 Treaty of Shimonoseki, which forced China to cede Taiwan to Japan. Beijing’s reaction to Japan’s naval movements was swift and fierce, framing it as an affront to national pride.
The People’s Liberation Army Daily asserted that Japan’s act was “damaging the feelings of the Chinese people,” illustrating how historical grievances are woven into contemporary conflicts. Beijing maintains that the Taiwan Strait is internal water, despite international norms suggesting otherwise. China’s foreign ministry condemned Japan’s actions as a “dangerous plot,” further intensifying tensions.
Japan’s increasing naval presence, marked by multiple transits through the strait since September 2024, highlights its growing alignment with U.S. efforts to promote freedom of navigation in the region. This isn’t just about asserting rights in a single waterway; it reflects a broader commitment to uphold maritime principles that many nations regard as customary. The United States, acting as a guarantor of Taiwan’s security, contends that UNCLOS allows for unhindered navigation, a view China disputes.
The stakes here are immense. The Taiwan Strait is a critical artery for global trade, with about 44 percent of the container fleet passing through annually. This strait is vital for international shipping and regional energy supplies, where significant amounts of crude oil destined for Japan and South Korea travel through. China’s control over Taiwan would allow it to exert restrictive measures on maritime transit, raising serious concerns about freedom of navigation and international trade stability.
Beijing’s military responses, such as the dual naval operations orchestrated by the PLA Eastern Theater Command, indicate not just defensive posturing but an operational strategy that could potentially encircle U.S. and allied forces. The PLA’s characterization of these movements as routine training is contradicted by the strategic context, suggesting that they are provocations meant to showcase military capability and resolve.
Furthermore, the Liaoning’s deployment could serve as a precursor to China conducting larger-scale joint exercises, likely intending to integrate multiple carrier strike groups in the South China Sea. Past operations have illustrated China’s ambition to enhance its naval power significantly, with projections suggesting it could triple its fleet by 2035, making the People’s Liberation Army Navy a formidable rival to the U.S. Navy.
In conclusion, the recent military maneuvers by both China and Japan serve as crucial indicators of shifting power dynamics in the Asia-Pacific region. The implications are profound, as both nations test the limits of their naval capabilities while navigating complex historical grievances and current geopolitical realities. As tensions rise, the essential question remains: how will these developments shape the future balance of power in an increasingly contested maritime landscape?
