Trump Orders U.S. Nuclear Tests Amid Fears of Chinese Expansion

Just minutes before his long-anticipated meeting with Chinese President Xi Jinping, U.S. President Donald Trump announced that the United States would “begin testing U.S. nuclear weapons on an equal basis with China and Russia.” The order, made public just before the summit, marks a sharp break with a 33-year moratorium on U.S. nuclear detonations and signals a major turn in global nuclear policy. Trump’s declaration, though lacking specific details, is widely interpreted as a warning to both Beijing and Moscow—nations he accuses of secretly conducting underground nuclear tests.

The United States has not conducted a nuclear explosion since 1992, while China’s last known test was in 1996 at Lop Nor, Xinjiang. Both countries signed the Comprehensive Nuclear-Test-Ban Treaty (CTBT) but never ratified it, agreeing informally to abide by its restrictions. Trump’s decision raises the prospect that this informal moratorium could soon end.

China’s Expanding Nuclear Program

Although Beijing has officially denied any violations of the moratorium, satellite imagery and independent analysis show extensive activity at its Lop Nor testing site. Analysts report new tunnel shafts and the installation of massive drill rigs—signs consistent with preparations for underground testing. According to researcher Renny Babiarz, the scale of construction “indicates a significant investment of time and money within a secured area of national strategic importance.”

Historically, China’s nuclear ambitions were constrained by limited resources and a doctrine of minimal deterrence. Mao Zedong once dismissed nuclear weapons as a “paper tiger,” even as his government raced to develop them in the 1960s. Assisted initially by Soviet scientists and propelled by the return of rocket engineer Qian Xuesen from the United States, China built a modest but potent arsenal aimed primarily at deterring the Soviet Union.

That restraint has vanished. Since around 2020, China’s People’s Liberation Army Rocket Force has expanded its missile sites, developed new long-range weapons, and built hundreds of new silos across remote regions. Military parades have showcased intercontinental ballistic missiles capable of striking anywhere on Earth, part of what experts now call China’s emerging “nuclear triad”—land-, sea-, and air-based deterrence.

Beijing Denies Testing, Calls for Restraint

Following Trump’s announcement, Chinese Foreign Ministry spokeswoman Mao Ning rejected accusations of secret testing, insisting that “China has abided by its commitment to suspend nuclear testing.” She emphasized Beijing’s policy of “no first use” of nuclear weapons and urged Washington to maintain the global moratorium. “We hope the U.S. will take concrete actions to safeguard the international nuclear disarmament and non-proliferation regime,” she said.

China’s official stance portrays it as a responsible nuclear power seeking stability. However, its recent construction, combined with secrecy and an aggressive modernization push, tells a more complex story. The U.S. Department of Defense estimates that China could field over 1,000 nuclear warheads by 2030—a fourfold increase from today’s stockpile.

The Return of Testing and What It Means

Trump has accused China, Russia, North Korea, and Pakistan of conducting secret nuclear tests, saying, “Russia’s testing, and China’s testing, but they don’t talk about it. I don’t want to be the only country that doesn’t test.” In a televised interview, he added, “They test way underground where people don’t know exactly what’s happening. You feel a little bit of a vibration—they test and we don’t.”

The White House has not clarified whether Trump intends to conduct full nuclear detonations or “system tests,” which stop short of actual explosions. Energy Secretary Chris Wright later suggested that these tests would be “non-critical”—evaluating components and delivery systems without a nuclear blast. Still, experts warn that even symbolic testing could unravel decades of restraint and ignite a new arms race.

The Hidden Dangers for the United States

China’s rapid nuclear expansion poses a significant challenge to U.S. strategic dominance. For decades, America and Russia have held roughly 90 percent of the world’s nuclear weapons, each maintaining more than 5,000 warheads. China’s push toward parity could erode that balance and complicate deterrence strategies in the Indo-Pacific. Analysts fear that Beijing’s pursuit of launch-on-warning systems and lower-yield warheads introduces dangerous ambiguity—blurring the line between conventional and nuclear conflict.

Some experts believe China’s buildup is designed not merely to defend its sovereignty but to deter U.S. intervention in a Taiwan conflict or future Pacific crisis. Others view it as part of Xi Jinping’s broader campaign to elevate China as a global superpower capable of matching American strength in every domain.

Corruption and Power Struggles Behind the Arsenal

Despite the scale of its nuclear expansion, China’s program has been plagued by corruption and secrecy. The PLA Rocket Force has been one of the main targets of Xi’s sweeping military purges since 2022, with several senior officers arrested or dismissed. The turmoil has raised questions about control, accountability, and the reliability of China’s command structure over its growing nuclear arsenal.

A Global Crossroads

The world now faces an unsettling question: will the moratorium that held since the Cold War finally break? Trump has yet to announce when the United States will conduct its first test, but his order signals an end to patience with opaque rivals. As both Washington and Beijing accuse each other of provocation, the era of nuclear restraint appears to be slipping away.

China insists it is still committed to peace and stability. Trump insists the U.S. will not stand idle while others prepare in secret. Between these two positions lies a stark reality—the return of a nuclear competition that could define the century.
