Congress’s China Military Report Warns of a Narrowing Window for Deterrence

For more than twenty-five years, Congress has required the Department of War to submit an annual report on China’s military and security developments. Viewed collectively, these assessments chronicle China’s steady transformation from a regional defense force into a military designed to challenge the United States and dominate the Indo-Pacific. The latest report concludes that this shift is well advanced, operationally tested, and increasingly focused on near-term warfighting objectives.

China’s military strategy centers on the First Island Chain, stretching from Japan through Taiwan to Southeast Asia—an area Beijing openly identifies as decisive for regional control. As China’s economic power has expanded, so has its ambition to project military force beyond Asia, in line with its goal of building a “world-class” military by 2049.

The People’s Liberation Army (PLA) explicitly measures its doctrine, planning, and capabilities against what it calls the “strong enemy” of the United States and is organizing for what Chinese planners describe as national total war.

According to the report, China’s historic military buildup has made the U.S. homeland increasingly vulnerable. Beijing now fields a growing mix of nuclear weapons, long-range conventional strike systems, advanced naval and air platforms, cyber capabilities, and space assets capable of threatening U.S. forces, allies, and critical infrastructure. In 2024, Chinese cyber campaigns such as Volt Typhoon penetrated U.S. critical infrastructure, demonstrating the ability to disrupt military mobilization and impose societal costs at the outset of a conflict.

Most significantly, the report finds that the PLA remains on track to meet its 2027 objectives. These include the ability to achieve a “strategic decisive victory” over Taiwan, establish a “strategic counterbalance” against the United States in nuclear and other strategic domains, and exert “strategic deterrence and control” over neighboring states. In practical terms, the report assesses that China expects to be prepared to invade Taiwan by the end of 2027.

To support this goal, the PLA has refined multiple options for forced unification, including amphibious invasion, large-scale missile and air strikes, and maritime blockade. Throughout 2024, Chinese forces rehearsed key elements of these scenarios, including strikes on land and sea targets, attacks on U.S. forces in the Pacific, and the isolation of critical ports. Chinese strike systems now have the range to reach 1,500 to 2,000 nautical miles from the mainland, posing a significant challenge to U.S. force projection.

China’s military expansion is driven by sustained defense spending and rapid technological development. Since the first full year of Chinese leader Xi Jinping’s tenure, China’s announced defense budget has nearly doubled, while investments in artificial intelligence, biotechnology, hypersonic weapons, and space systems continue to accelerate.

Against this backdrop, the report states that under President Trump’s leadership, the United States seeks stability without illusion. Washington does not aim to dominate or humiliate China, nor to provoke confrontation. As outlined in President Trump’s National Security Strategy, the U.S. objective is deterrence through strength—preventing any power from dominating the Indo-Pacific or coercing U.S. allies. The Department of War emphasizes readiness, credible military power, and selective military-to-military communication with the PLA to reduce the risk of miscalculation while preserving U.S. freedom of action.

China’s national strategy is anchored in what it calls the “great rejuvenation of the Chinese nation” by 2049, combining expanded global influence with the creation of a military capable of fighting and winning wars. Beijing defines three non-negotiable “core interests”: maintaining Communist Party rule, sustaining economic development, and defending and expanding China’s sovereignty and territorial claims.

These core interests are explicitly applied to Taiwan and disputed territories in the South China Sea, the Senkaku Islands, and India’s Arunachal Pradesh. The Chinese Communist Party portrays unification and territorial consolidation as essential to national rejuvenation and treats criticism or resistance as existential threats, labeling dissent in Hong Kong, Xinjiang, Tibet, and Taiwan as separatism allegedly backed by foreign powers—typically a reference to the United States.

The report concludes that while China is preparing for a high-end conflict with the United States, the United States is working to prevent such a war by making aggression irrational. U.S. deterrence relies on maintaining sufficient forces in the Indo-Pacific to defeat an invasion attempt without matching China ship-for-ship. Instead, it emphasizes qualitative advantages such as stealth submarines, fifth-generation aircraft, long-range precision strike, superior pilot training, and extensive combat experience.

Alliance coordination further strengthens deterrence. Cooperation with Japan, Australia, the Philippines, and South Korea complicates Chinese planning and multiplies U.S. combat power. Initiatives such as AUKUS and expanded U.S. base access in the Philippines extend reach, resilience, and sustainment across the region.

The United States also retains asymmetric advantages that are difficult for China to replicate, including quieter submarines, more experienced crews, and significantly higher pilot flight hours. The report frames deterrence as both denial and punishment—convincing Beijing it cannot win militarily, while signaling that even a limited success would come at overwhelming economic, political, and strategic cost.

While China continues to improve its military capabilities across all domains, the report concludes that whether peace is preserved will depend on whether deterrence holds as the PLA approaches its self-declared 2027 milestone.
