Abstract:
This report examines the intersection of China’s nuclear modernization and cross-Strait tensions, especially how they might play out during a crisis, contingency, or conflict involving China, Taiwan, and the United States. Beijing is rapidly modernizing its nuclear arsenal to make it larger and more sophisticated. Changes include an increase in warhead numbers from more than 400 today to potentially 700 by 2027 and more beyond, consolidating a nuclear triad, developing new delivery systems, and digging at least 300 new missile silos. Some factors still could constrain the growth of China’s arsenal or the policies that shape the way Chinese leaders employ it. They range from fissile material stocks to competing military spending priorities, considerations about China’s international reputation, and upholding Beijing’s claimed No First Use policy. But nearly all those constraining factors either already have weakened or could do so in the near future. China’s expanding nuclear arsenal suggests that the force will be designed to fulfill new missions. Some part of Beijing’s buildup surely is meant to bolster its second-strike retaliatory capability in the face of what China perceives as shifts in U.S. conventional and nuclear capabilities and policies. China’s long-term goal for the expansion, however, could be more ambitious and potentially even include seeking to build an arsenal on par with Washington’s and Moscow’s. Meanwhile, China continues to ramp up pressure on Taiwan using political, economic, and military tools. Beijing’s campaign could provoke more crises in the coming years. The three major roles that nuclear weapons could play for China when dealing with cross-Strait crises or conflicts are: to shield China from U.S. nuclear coercion, to threaten Chinese nuclear use to try to forestall U.S. intervention, and to conduct a limited Chinese nuclear detonation in an attempt to force U.S. and Taiwanese capitulation. The report concludes with recommendations for U.S. policymakers. It calls for carrying out U.S. nuclear modernization plans to deter China but avoiding nuclear arms racing as a strategy in itself. It recommends incorporating nuclear elements into contingency planning and scenario exercises related to Taiwan, both unilaterally and with allies and partners. The report then calls for improving Taiwan’s conventional military capabilities while maintaining a consistent U.S. policy on cross-Strait issues and ensuring Taiwan forgoes pursuing indigenous nuclear weapons. Finally, the report argues in favor of pushing forward tough-minded bilateral engagement with Beijing on strategic stability and security issues while crafting a multilateral arms control strategy that builds coalitions to incentivize China to join and impose costs on Beijing if it opts to stay outside of key agreements.

Abstract:
This report examines the nuclear policies and postures of the United States and its three primary nuclear adversaries: China, Russia, and North Korea. It concludes that the world is entering a multipolar nuclear era, which is unprecedented, and far more complex and challenging than the Cold War. The current nuclear order has been gradually shifting over the past decade. Russia remains the United States’ only nuclear peer, but the arms control regime that constrained the superpowers’ nuclear arsenals is disintegrating. Relations between Washington and Moscow have worsened since Russia’s full-scale invasion of Ukraine and Russian President Vladimir Putin’s nuclear saber-rattling. China’s nuclear arsenal is growing in size and sophistication, potentially enabling Beijing to launch conventional attacks behind its nuclear shield. This development will shape both competition among Beijing, Washington, and Moscow and potential future military confrontations. Similarly, North Korea has a small but expanding number of deployed nuclear weapons and is improving its missile technology. In this new nuclear environment, the United States must deter two nuclear-armed great powers as well as a regional nuclear power from launching conventional and nuclear attacks on itself and its allies. As the number of nuclear-armed states grow, interactions become more complex and the risks of miscalculation and misperception increase. The ramifications of this new reality are not well understood, aside from the implication that there is a growing risk that nuclear weapons might be used. The study’s findings have five primary implications for American policy and nuclear posture. To improve strategic stability and enhance deterrence, the United States should take several courses of action.

3. Building a Flywheel: The Biden Administration's Opportunity to Forge a New Path with North Korea

Abstract:
As the United States seeks to maintain a level of stability in its increasingly competitive relationship with China, North Korea has the potential to complicate their intensifying rivalry. Dealing with North Korea is a complex endeavor that requires deft handling by both nations because the stakes are high and instability can spread rapidly. For decades, China has been seeking to bolster the stability of the Kim family regime and increase China’s economic engagement with North Korea, to the point where North Korea Inc.—the Kim regime’s network of elite state trading companies—has embedded itself in major commercial hubs throughout China. By prioritizing the stability of the North Korean regime over denuclearization in its policy actions, China created a loophole in which the North Korean regime could enjoy economic benefits without having to do denuclearization work. Beijing thus impeded the development of a connection to a larger process in which major denuclearization activity would be paired with major economic and diplomatic concessions. In contrast to China’s sustained engagement with North Korea, U.S. policy toward North Korea over the last decade has focused substantially on sanctions implementation. There was a brief period of summit diplomacy during the Trump administration, but those efforts failed to bring about progress toward denuclearization. The North Korean nuclear issue has mutated into a much more complex challenge that no longer fits into past policy molds that rely heavily on sanctions implementation. President Joe Biden’s administration will need to recognize that North Korea under Kim Jong Un has become highly resilient to U.S. policy tools such as sanctions, largely due to far-reaching advancements in the relationship between the Chinese Communist Party (CCP) and the Workers’ Party of Korea (WPK) as well as the migration and embedding of North Korea Inc. deep inside the Chinese national economy.

Abstract:
The United States’ current diplomacy with North Korea has enduring implications for its strategic competition with China. Yet within the American foreign policy establishment, rising to the China challenge and managing the nuclear threat emanating from North Korea are often treated as two distinct rather than connected strands of the United States’ agenda in Northeast Asia. The rationale for maintaining some degree of bureaucratic and substantive segmentation between the two issue sets is well-founded. Addressing the North Korean threat warrants energy, resources, attention, and expertise independent of the “great power competition” framework delineated in the 2017 National Security Strategy and the 2018 National Defense Strategy. But excessive stovepiping may, at best, cause Washington to leave opportunities on the table that could advance its regional priorities, and at worst to risk the creation of mutually incompatible approaches to North Korea and China. U.S. negotiations with North Korea have already created strategic openings for China. The “security guarantees” that Pyongyang has demanded include, for example, the cessation of U.S. joint military exercises with South Korea and the removal from the Korean Peninsula of all American “strategic assets” such as nuclear-capable air and naval assets as well as anti-missile systems that could also be leveraged in a military contingency with China. As U.S. negotiators have locked horns with North Korean interlocutors since President Donald Trump and Kim Jong Un’s initial diplomatic foray in June 2018, China has touted its role as a champion of peace and stability on the Korean Peninsula, while using its relative proximity to Pyongyang to systematically undercut America’s approach. During the United States’ “maximum pressure” campaign in 2017, Beijing cast Pyongyang a vital lifeline, facilitating illegal ship-to-ship transfers of North Korean coal and petroleum in 2018, while leading a concerted push with Russia at the U.N. Security Council to try to fragment the North Korean sanctions regime. And China is poised to open the floodgates of investments into North Korea, particularly through strategic infrastructure projects in the event that Pyongyang’s demands for the relief of international sanctions yield results. Despite all of this, U.S. officials at the highest levels have publicly downplayed intimations of China’s counterproductive activities, thereby validating Beijing’s narrative that it has played a constructive role in supporting the United States’ approach to North Korea.
