Tensions between the U.S. and China are intensifying over nuclear arsenals, as a recent report indicates that the U.S. believes China is rapidly expanding its nuclear capabilities. An American official noted that within four to five years, China may attain 'strategic parity' with the U.S. nuclear arsenal. This situation heightens concerns regarding the future of nuclear deterrence and arms control between the two nations, as differing perspectives emerge on these critical issues.

The Chinese government has rejected U.S. accusations concerning its nuclear modernization program, which includes claims about an undisclosed small nuclear test conducted in 2020. Despite these rejections, U.S. officials, including Christopher Yiu, Assistant Secretary of State for Arms Control, continue to voice concerns about China's lack of transparency regarding its expanding nuclear capabilities. This has led to a further deterioration in trust between the two superpowers, leaving the potential for miscalculations that could escalate into serious conflicts.

As global powers grapple with the dynamics of nuclear strategy, this development raises questions about the effectiveness of existing arms control agreements and the need for new frameworks tailored to address the evolving nuclear landscape. The U.S. and China must navigate these tensions carefully to prevent a potentially destabilizing arms race that could have worldwide implications.
