Is China a Threat to U.S. Interests?

China poses serious, multidimensional challenges to U.S. interests, though the relationship is more accurately described as a complex mix of competition, friction, and selective cooperation rather than outright hostility. Here's the current picture based on 2026 assessments:

Military and Security Concerns

The U.S. intelligence community continues to flag China as a top-tier security concern. The 2026 ODNI Annual Threat Assessment names China alongside Russia, Iran, and North Korea as primary threat countries, identifying the People's Republic of China, Russia, Iran, and North Korea as primary threat countries and highlighting that military and economic cooperation among these four nations is intensifying.

On the nuclear front, the U.S. Defense Department assesses China's nuclear stockpile in the low 600s through 2024, projecting over 1,000 warheads by 2030. Missile capabilities are also expanding rapidly, with projections suggesting the missile threat to the U.S. mainland will grow from over 3,000 missiles currently to more than 16,000 by 2035.

On Taiwan, the risk picture is nuanced. A 2026 U.S. intelligence assessment noted that an imminent attack is unlikely, as Beijing prefers to achieve unification without the use of force, and recognizes that an amphibious assault would be extremely difficult and carry a high risk of failure, especially if the U.S. intervenes. Still, China's military is making "steady but uneven progress on capabilities that it would use in any" potential Taiwan operation. Analysts broadly agree regional security risks, especially over Taiwan, continue to pose the greatest threat to regional stability, while miscommunication and misperceptions increase the risk of crisis escalation.

Cyber and Technology Threats

This is where the threat assessment is most unambiguous. U.S. intelligence has concluded that China remains the most serious, widespread, active, and persistent cyber threat to critical infrastructure and government and private networks in the United States, with ongoing attempts by China to penetrate US government and private networks.

Support for U.S. Adversaries

China's role in enabling Russia is a notable strategic concern: the strengthening of Sino-Russian ties has bolstered Russia's capacity to sustain the war in Ukraine and resist external pressures, as China's imports of Russian oil and natural gas provide Moscow with crucial revenue to withstand sanctions, while China's exports of dual-use military and civilian technologies help maintain Russia's defence production and diminish its motivation for a ceasefire.

Economic Competition

Rather than pure hostility, economic ties reflect a "coupled competition" dynamic. Economic security has become a central arena of competition, as both governments increasingly view trade, technology, and investment through a national security lens. Congress has taken a hardline legislative stance—the 2026 National Defense Authorization Act incorporates several acts directly targeting China, including the BIOSECURE Act and the FIGHT China Act, prompting China to react strongly and threaten countermeasures.

Yet paradoxically, supply chains remain deeply intertwined: even when Washington and Beijing "de-risk" in tech, they may still be tightly coupled through energy transition supply chains, and that coupling can reduce conflict through mutual dependence or increase leverage through weaponization risk, depending on the sector.

Room for Cooperation

Importantly, experts don't view the relationship as purely adversarial. A June 2026 Track II dialogue found participants identified several areas where cooperation remains not only possible, but desirable, including the significant economic relationship, AI safety, crisis management, military-to-military communications, and fentanyl enforcement. Expert surveys entering 2026 show deep divisions: about one-third of experts think the relationship is likely to become more antagonistic, another one-third predict it will become more cooperative, and the remaining third assess it will stay about the same.

Bottom Line

China represents a genuine strategic competitor and, in specific domains (cyber espionage, military buildup, support for Russia), a direct threat to U.S. security interests. However, it is not a monolithic adversary in the way Cold War framing might suggest—economic interdependence, mutual crisis-avoidance incentives, and areas of overlapping interest (AI safety, fentanyl, climate) create space for managed competition rather than inevitable conflict. The most accurate characterization for 2026 is one of "cold enough to avoid direct war, but hot enough to reshape supply chains, technology diffusion, commodity pricing, and alliance behavior," as one analysis put it—a rivalry requiring careful management rather than a binary "threat vs. not-a-threat" framing.
