China’s Expanding Influence Reshapes Asian Competition

President Xi Jinping personally opened Shanghai’s World Artificial Intelligence Conference on July 17, departing from the usual practice of assigning the event to a senior party official. He called for international alignment on AI development strategies, governance rules, and technical standards, while proposing capacity-building support for Global South countries. Xi also said China would keep AI secure, controllable, and under human control through laws, technological monitoring, early-warning systems, and emergency-response mechanisms. His address presented Beijing as a prospective leader in global AI governance amid competition with the United States.

China is reinforcing its AI ambitions through semiconductor expansion and lower-cost model deployment. CXMT, China’s fourth-largest DRAM producer, is considering a second memory-chip plant in Beijing after a record $8.6 billion mainland semiconductor listing. It already operates three 12-inch DRAM fabs, each reportedly capable of producing roughly 100,000 wafers monthly, and planned facilities in Shanghai and Hefei could raise total capacity above 600,000 wafers per month. Separately, DeepSeek released its V4-Flash model at a reported benchmark cost of about three cents, far below leading Western models, though it scored below frontier systems on composite assessments of complex tasks.

Japan is responding to Chinese economic pressure and regional military activity with supply-chain adjustments and expanded strike capabilities. Beijing has imposed targeted export controls affecting Japanese defense and dual-use technology firms, including restrictions in rare earths, an area where China holds nearly 90 percent of global refining capacity. On July 29, the destroyer JS Chokai test-fired a U.S.-made Tomahawk cruise missile with a range exceeding 1,600 kilometers. The next day, Japan began flight tests of an air-launched Type 12 anti-ship missile with a reported range approaching 1,000 kilometers. China’s Coast Guard, which has roughly 680 vessels, is also conducting increasingly assertive operations in contested waters around Taiwan and in the South and East China Seas.

Washington and Tokyo have added financial coordination to their security relationship. Japan and the United States confirmed a joint yen-buying intervention after the currency fell to a 40-year low, the first coordinated action of this type since 2011. Japanese central-bank data indicated that Tokyo may have sold nearly $59 billion to support the yen before the confirmed joint intervention. Meanwhile, India and China resumed limited Himalayan border trade through three mountain passes after a six-year suspension following the COVID-19 pandemic and the 2020 Galwan border clash.

China’s AI program is becoming a competition over governance and market structure, not simply model performance. Xi’s call for Chinese influence over global AI standards, paired with large-scale domestic memory-chip expansion, suggests Beijing seeks greater control over the infrastructure, rules, and commercial ecosystems that shape AI adoption. If Chinese companies can offer capable models at substantially lower prices, they could gain users among cost-sensitive enterprises and governments, particularly where access to expensive frontier systems is constrained. This would give Beijing influence through technological adoption even where Chinese systems do not lead in the most demanding benchmarks.

Japan’s response reflects a converging economic-security and military deterrence strategy. Chinese restrictions on rare earths and dual-use technology firms create direct incentives for Tokyo to reduce exposure to Chinese-controlled supply chains. Japan’s acquisition of long-range Tomahawks and development of an extended-range Type 12 missile add military tools that could complicate Chinese or Russian planning around regional sea lanes and potential Taiwan contingencies. The combination matters because economic coercion may accelerate defense investments, while stronger Japanese counterstrike capabilities could make bilateral disputes harder to compartmentalize.

The joint yen intervention demonstrates that U.S.-Japan alignment now extends into financial stability. The two governments acted after yen weakness and pressure on Japanese government bonds raised concerns about spillover effects, including higher U.S. borrowing costs. This creates a practical precedent for coordinated economic action when domestic Japanese instability could affect American financial interests. Future coordination may depend on whether currency support and prospective Japanese monetary tightening can produce a sustained recovery, rather than only deterring short-term speculative pressure.

Regional competition remains compatible with selective economic engagement. India’s resumption of limited border trade with China shows that bilateral normalization can proceed in narrow commercial channels despite the legacy of the Galwan clash. At sea, however, China’s large coast guard fleet continues to give Beijing a tool for pressing territorial claims below the threshold of naval conflict. A principal indicator is whether China broadens export controls and coast guard operations while Japan expands supply-chain diversification and fields its new missile systems. Those developments would show whether deterrence and economic adaptation are stabilizing competition or entrenching more adversarial blocs.
