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:
The United States–Republic of Korea (ROK or South Korea) alliance has entered a critical phase. In 2023, the two countries will commemorate the 70th anniversary of signing their bilateral mutual defense treaty. This year also marks the first full year under national leaders President Joe Biden and President Yoon Suk Yeol. After several challenging years in the two countries’ relationship, ties are improving. Better alliance relations have, unfortunately, coincided with a deterioration in the regional and global security environment, specifically due to threats from North Korea, China, and Russia. This report examines the U.S.-ROK alliance as it adapts to the new regional context by exploring how the United States and South Korea can sustain and deepen their relationship in three vital policy areas: coordination on China, alignment in minilateral and multilateral settings, and defense technology collaboration. Perhaps the biggest shift in alliance priorities in recent years has been the growing importance of the China challenge. During Chinese Communist Party General Secretary Xi Jinping’s decade in power, Beijing has adopted a more muscular foreign policy. Both the United States and South Korea have reshaped their approaches toward China in response. ROK concerns about China have grown as Beijing shields Pyongyang and acts aggressively elsewhere in the region, including toward Taiwan. But South Korea’s approach to China will continue to differ from that of the United States. The allies have divergent preferences regarding the speed, manner, and degree of partial decoupling with China. Moreover, South Korea’s deep trade ties with China will continue to make it vulnerable to Chinese political and economic coercion.

Abstract:
India-China border intrusions and clashes have become more frequent and threaten to lead to all-out conflict between the two Asian giants. In recent years, China has upped the ante in its border disputes with India through infrastructure development, military deployments, capability enhancements, and periodic efforts to encroach into territory controlled by India. The first deadly border clash between the two countries in 45 years occurred on June 15, 2020, in the Galwan River Valley, where 20 Indian troops and at least four Chinese People’s Liberation Army (PLA) troops were killed. More recently, on December 9, 2022, Chinese and Indian forces clashed along the disputed border in the mountains near Tawang in the northeastern Indian state of Arunachal Pradesh after an estimated 300 Chinese PLA soldiers tried to cross the border. While the Chinese and Indian militaries have since pulled back forces from the most contentious standoff sites where the 2020 buildup occurred and established temporary buffer zones, both sides retain high numbers of troops forward deployed along the disputed frontier, and there are several flashpoints that could erupt into another border crisis at any time. The most recent clash that took place near Tawang is a reminder that, even though recent attention has been focused on the Ladakh region, there are multiple trigger points along the 2,100-mile-long Line of Actual Control (LAC) that bear monitoring.1 With both China and India enhancing infrastructure and introducing new and advanced weapons systems on their sides of the disputed border, combined with forward deployments and heightened lack of trust, the chances for continued standoffs that could erupt into local or even full-blown conflict remain high.

Abstract:
Russia’s war in Ukraine has been a critical test of the depth of Sino-Russian relations. Since Russia’s invasion, China has remained an essential partner for Moscow. Although there have been limits to what Beijing has been willing to do for Russia, China has served as a vital lifeline for the Kremlin including by parroting Russian talking points about the war, increasing purchases of Russian oil and gas, and continuing to export microchips and other component parts to Moscow cut off by the West. Warnings by senior U.S. officials that China is contemplating providing Russia with lethal military aid in support of its war against Ukraine underscore the depth of their partnership.1 Emerging reports that Chinese companies have provided rifles and dual-use equipment such as drone parts and body armor only add credibility to these warnings.2 Although it remains unclear at the time of writing whether China will ultimately decide to send lethal aid to Russia, the last year has provided further evidence that Russia and China are deeply aligned and that the persistence and evolution of their partnership will continue to pose challenges that the United States and its allies must navigate. This working paper will focus on the challenges that Russia-China military cooperation poses to the United States and its allies and partners. This aspect of their relationship has been one of the most consequential dimensions of their deepening partnership. Already, China has obtained key capabilities from Moscow such as Su-27 and Su-35 fighter aircrafts, S-300 and S-400 air defense systems, and anti-ship missiles, which bolster China’s military posture in the Indo-Pacific.3 Russia too has benefited from a large market for its arms sales and access to technological components it can no longer access following the imposition of Western sanctions in 2014—a need that has grown exponentially since Russia’s reinvasion of Ukraine in February 2022. Meanwhile, more frequent and elaborate joint exercises have signaled to onlooking countries the two partners’ mutual support for each other’s security priorities and willingness to push back against the United States. In the context of Russia’s ongoing war against Ukraine and increasing U.S.-China tensions in the Indo-Pacific, it has become even more urgent to understand how future military cooperation between Russia and China could evolve and what it would mean for the United States and its partners. This memo examines this aspect of the partnership, including what is driving it, how it has evolved following the 2022 invasion of Ukraine, and the implications for the United States and its allies and partners.

5. “Production Is Deterrence”: Investing in Precision-Guided Weapons to Meet Peer Challengers

Abstract:
This report explores whether the fiscal year (FY) 2024 U.S. defense budget request for key conventional precision-guided munitions (PGMs) aligns with the 2022 National Defense Strategy (NDS) by prioritizing weapons needed for the “pacing challenge” China poses and dealing with the “acute threat” from Russia, while taking risk in lower priority areas. The FY24 presidential budget request builds on the shift that began in FY23 to support the NDS: increasing buys of key long-range and antiship missiles to prepare for a fight in the Pacific, starting to fill the cruise missile defense gap, bolstering production of the land-attack weapons needed in Europe, and test-running multiyear procurement and large lot procurement for key munitions to strengthen the defense industrial base. In the Department of Defense’s (DoD) budgeting process, ships, aircraft, and vehicles tend to be prioritized, leaving missiles and munitions with inadequate funding. Moreover, the Pentagon does not take a holistic approach to procuring key conventional PGMs, making it difficult to assess the joint portfolio. If the United States is going to effectively compete with China and Russia, that needs to change. To deter and—if deterrence fails—defeat China, the DoD needs large stockpiles of standoff missiles, maritime strike weapons, and layered air and missile defenses. The authors conclude that after years of underinvestment, the DoD is buying more long-range and medium-range missiles, which would be essential in a China war fight. While historically the Pentagon has overinvested in bombs and missiles to attack targets on the land and neglected antiship weapons, the FY24 budget saw a notable uptick in air-launched antiship weapons. For the past decade, the DoD has consistently invested in air defenses, but its purchases have focused on expensive ballistic missile defense interceptors, while neglecting cruise missile defenses. The FY24 budget reverses this trend. Additionally, the DoD is investing in PGMs to arm Ukraine and replenish American and allied stores of weapons that are needed to counter Russia. Except for surface-to-air missiles, the weapons for Ukraine are relatively short-range land-attack PGMs that U.S. forces do not need in the Indo-Pacific. A large portion of the funding for these weapons is coming from Ukraine supplemental appropriations, not the base defense budget. Supplemental appropriations are also resourcing significant investments in U.S. production lines, but the DoD has made only moderate progress rebuilding American stockpiles of the PGMs given to Ukraine.

Abstract:
Two tectonic trends in the international security environment appear to be on a collision course. The first trend is the intensifying geopolitical rivalry between the United States and the People’s Republic of China (PRC or China). The second trend is the rapid development of artificial intelligence (AI) technologies, including for military applications. This report explores how the United States can manage strategic risks—defined as increased risks of armed conflict or the threat of nuclear war—that could be created or exacerbated by military AI in its relationship with China. It begins by providing an overview of China’s views on and policies toward AI. Beijing sees AI playing roles in both its civilian economy and the modernization of its military, the People’s Liberation Army (PLA). At home, Chinese leaders want to leverage AI to boost growth and innovation, address economic and social challenges, and secure the Chinese Communist Party’s (CCP) domestic rule. AI also plays a key role in China’s military ambitions, especially its goal to become a “world-class military” by midcentury, in part through the “intelligentization” of its forces. Intelligentization relies on integrating AI and other emerging technologies into the joint force with the goal of gaining an edge on the United States. China argues that its governance model, including its military-civil fusion policy, gives Beijing a competitive advantage over Washington. Realization of that vision, however, remains uncertain and will require China to overcome external and internal obstacles.

7. Rolling the Iron Dice: The Increasing Chance of Conflict Protraction

Abstract:
The prospect of a Sino-American war looms on the horizon. No scenario for such a conflict has garnered more interest than the potential invasion of Taiwan by the People’s Republic of China (PRC). In the United States, discussions have focused on the early days of a conflict, in particular sinking the PRC’s amphibious fleet.1 Both the United States and the PRC place great emphasis on offensive military operations that heavily use the fruits of the precision strike revolution (PSR).2 This focus on early offensive action leads immediately to considerations of forces and weapons. U.S. defense planners are unsurprisingly most comfortable with the dynamics of short, sharp wars, having spent the past decade focused on deterring or defeating adversary faits accomplis, short and often opportunistic campaigns of aggression. Speed, political sophistication, and immediate military overmatch seemed to be the key ingredients for victory. Russia’s seizure of Crimea in 2014 was seen as a template for other future aggressors to follow.3 Prolonged wars of attrition, particularly those involving the United States, were thought no longer possible. Russia’s subsequent invasion of Ukraine in 2022 turned this vision on its head, demonstrating the military and political consequences of trying and failing to obtain a similar fait accompli on a larger scale. The ongoing Russian experiences in Ukraine indicate a need to reevaluate such thinking and consider the potential of protraction in the context of a hypothetical U.S.-PRC conflict. Most work on this topic has considered only the initial days and weeks of hostilities, usually over Taiwan or in the South or East China Seas.4 There has been comparably little discussion of what comes after.5 There are three key concepts that inform the following discussions: exhaustion, sanctuary, and protraction. Exhaustion is the point when large-scale offensive operations are no longer possible as offensive military capabilities have been used up. Afterward, some period of reconstitution and recovery is needed. This requires sanctuary, the relative freedom from attack sufficient for the rebuilding of military forces and capacities. Protraction occurs after at least one cycle of exhaustion and recovery. It is closely tied to pre-conflict leadership beliefs about the length of the looming war. A simplified definition of a protracted war is a conflict that lasts longer than leaders expect; it is a mismatch between political-military expectations and reality. Doctrinal developments in both the PRC and the United States, influenced by improvements in technology, place significant emphasis on the early stages of conflict and rapid, offensive operations. The emphasis by both the PRC and the United States on the early stages of the conflict can be seen in the PRC’s system destruction warfare and United States’ denial-centric concepts that aim for rapid decisive results.6 These approaches focus almost exclusively on the operational level of war, ignoring strategic factors animating the conflict and shaping its termination. Should PRC President Xi Jinping commit the PLA to seizing Taiwan by force, enter a war with the United States, and “roll the iron dice,” protraction appears increasingly likely, contrary to most contemporary military thinking and preparation.

8. No Winners in This Game: Assessing the U.S. Playbook for Sanctioning China

Abstract:
The relationship between the United States and the People’s Republic of China (PRC) is marked by both geopolitical tensions and deep economic linkages. While policymakers may have once believed that economic integration would inject stability into the overall relationship and provide a deterrent to conflict, that idealistic vision has been shaken by Russia’s brutal invasion of Ukraine. No longer can the United States and its partners assume that the PRC’s economic interest in retaining ties to the global economy will override its nationalist impulses. The once unthinkable idea of imposing severe sanctions on China has become a strategic imperative to consider, as one of a range of measures that the United States and its partners may consider if relations with the PRC deteriorate further. Yet, sanctioning China represents a challenge more complex than any other in the modern era of sanctions. The scale and interconnected nature of China’s economy means that the damage from sanctions will not be contained in China; instead, the negative effects will rebound globally through China’s deep economic ties to nearly every country around the world, including the United States. China has substantial capacity in key economic areas, such as manufacturing, that provide it with important means to retaliate against U.S. sanctions or impose its own economic costs on the United States and its partners. This report seeks to advance policy debates on how to sanction China, if geopolitical conditions warranted doing so at scale. It builds on prior Center for a New American Security (CNAS) research, including a 2023 report that outlines how the United States currently uses a variety of sanctions tools to manage the strategic relationship with the PRC.1 A key finding of the earlier work is that the United States imposes sanctions at a relatively limited scale compared to the scope of challenges that exist in the bilateral relationship, with the notable exception of an increasing range of technology-related sanctions. A large divide separates the existing level of sanctions on China and the full range of economic measures that the United States may consider. This report attempts to envision that fuller range of economic measures and consider whether the use of sanctions would meaningfully advance U.S. interests during a potential conflict. The report begins, in chapter 1, with an assessment of the main economic and political characteristics that would determine China’s vulnerability to, and resolve to withstand, sanctions pressure. The concentration of power at the very top of the PRC’s political system, along with a willingness to subordinate economic objectives to political ones, indicate that China may have a high degree of resolve to absorb the costs of sanctions. China’s continued reliance on the U.S.-dominated global financial infrastructure is a key area of vulnerability to sanctions pressure. But, China retains significant economic leverage through its manufacturing relationships, as well as through the importance of its large domestic market to foreign multinational companies. Attempting to impose sanctions that are asymmetrically more painful to China will be a fraught exercise, given the degree to which China is embedded in global supply chains. In chapter 2, the report examines sanctions actions that the United States and its partners may impose during a conflict scenario, drawing from the sanctions playbook used against Russia and projecting adaptations that would be needed in the China context. The main objective of this analysis is to identify points of asymmetric leverage in the U.S.-China economic relationship, where imposition of a sanction would be more economically damaging to China than to the United States and its partners. The sanctions actions are examined through the lens of a ends-ways-and-means framework, loosely borrowing concepts from the defense community and mapping them into the economic domain. The value in such an exercise is to impose discipline in identifying why a particular economic measure may be taken and what the intended impact would be. It can also enhance the ability to integrate economic actions with those being considered in military or other domains. The report examines possible actions under three broad categories, based on the objective of the sanctions: technology denial, embargo of commodities and materials, and macroeconomic pressure. The research includes analysis by the CNAS Energy, Economic & Security team of economic data and research interviews with a wide range of sanctions, export controls, macroeconomics, trade and finance, and China experts in the United States, Europe, and Asia. In addition to examining potential sanctions options on a sectoral basis, the report also includes a company-by-company lens to assess the potential impact of sanctioning specific Chinese companies. The report finds that the U.S. options to impose harsh sanctions on China are severely constrained. U.S. options to deny militarily relevant technology to China are modest, at best. Certain areas, such as maritime capabilities, will be difficult to target due to the nearly entirely domestic supply chains of China’s main military shipbuilders. Other areas, such as semiconductors, cannot be targeted without running the risk of disruption to critical U.S. supply chains. Overall, efforts to deny technology to China require a longer time horizon to be effective and may have less utility in an immediate run-up period to a potential conflict. Attempts to use sanctions tools to deny commodities or materials to China will require innovation and the development of new sanctions tools. Key commodities, such as energy, are inherently substitutable and globally available, including from many countries that will likely not align with the United States in a conflict with the PRC. Building on the example of the oil price cap used in the Russia context, the United States and partners will need to consider novel policy approaches that provide positive economic inducements to align with U.S. policies, in addition to using traditional sanctions tools.

9. Resisting China’s Gray Zone Military Pressure on Taiwan

Abstract:
The People’s Republic of China (PRC or China) has sharply escalated its pressure campaign targeting the Republic of China (ROC or Taiwan) in recent years. Beijing appears likely to use Taiwan’s upcoming presidential election in January 2024 as a pretext to apply more pressure on the self-governing island, particularly in the “gray zone” using China’s military, the People’s Liberation Army (PLA), along with other tools of state power. There is no precise and commonly agreed upon definition of what gray zone activities are and are not. In general, though, the concept refers to actions that fall into the space between, on one side, peace and, on the other, full-scale kinetic war.1 Gray zone activities are coercive and aggressive but designed to stay below the threshold of triggering major conflict. China uses gray zone operations as part of a comprehensive strategy to pressure Taiwan that spans the areas of diplomacy, information, economics, and security. This policy brief examines one major component of that campaign: gray zone military and security operations. It starts by detailing the capabilities and tactics China uses to put security pressure on Taiwan. Then, it explains what Beijing seeks to achieve with those actions. The paper concludes with recommendations for how U.S. and Taiwan policymakers can resist and counter China’s gray zone operations.
