The U.S. withdrawal from the INF Treaty reflects Washingtons long-standing concern that the treaty constrained its ability to counter Chinas fast-growing missile forces in the Asia Pacific.

The INF Treaty is dead, and U.S. officials are arguing that its not just about Russias treaty violations but about responding to a Chinese military build-up and Beijings growing influence. This outcome reflects the impulsive decisionmaking of U.S. President Donald Trump and the influence of U.S. National Security Adviser John Bolton, a noted opponent of arms control. But more importantly, it reflects a widespread and long-standing concern in Washington about how the treaty constrained the United States capacity to counter Chinas fast-growing missile forces in the Asia Pacific. Now, for Chinese leaders, the message from the White House is loud and clear: the United States is fully committed to a strategic competition with China.

Chinas security community now fears that the United States may quickly develop and then massively deploy medium- and intermediate-range land-based missiles around the region. Even if Washington were to arm such missiles with non-nuclear warheads, this could challenge Beijings military capabilities and significantly shift the current balance near Chinas coast, making it harder for Chinato defend its sovereignty and territorial integrity. Chinese military strategists also believe that U.S. missiles would pose an unacceptable counterforce threat to the survivability of Chinas own small nuclear arsenal, compelling Beijing to take radical measures to build up its own nuclear capabilities.

Because of the lack of adequate locations for ground-based U.S. intermediate-range missiles to be based in the Asia Pacific, Washington would need to work closely with its regional allies to find appropriate deployment sites. From Beijings perspective, this means that Washington has an inherent interest in exaggerating the so-called China threatin the region to make its allies afraid and more willing to host U.S. intermediate-range missiles in countries like Japan and South Korea. Beijing sees efforts tostirup tensions to encircle China with an anti-China alliance as both a means and an end of U.S. strategy.

Abandoning the INF Treaty also removes any obstacle for the United States to develop and deploy other cutting-edge ground-based medium- and intermediate-range weapon systems, such as missiles with trajectory shaping vehicles that are effective at neutralizing enemy defenses and are cheaper and less complicated to build than hypersonic weapons. U.S. Army officials have spoken for months about the need for long-range precision fires, even before any mention by U.S. officials of an INF withdrawal. It is highly likely that China would try to counter new U.S. capabilities by doubling down on its own investments in similar technologies and other countermeasures. A broader arms competition that spills over into additional technological domains other than traditional ballistic and cruise missiles seems hard to avoid.

The withdrawal is likely to heighten existing tensions in the region. Chinasgeography and deployed missile systems in East Asia give Chinese officials confidence that the country has the capacity to outcompete the United States in the long run. In this respect, a buildup of new U.S. missiles around Chinas coast strengthens the Chinese view that the United States is pursuing a strategy of military encirclement against China, not merely looking out for U.S. interests in the region. Given the asymmetrically higher stakes involved, China cannot afford to back down.

U.S. officials who believe that they need new intermediate-range missiles to counter the China threat are creating a self-perpetuating cycle: China would react aggressively to perceived U.S. aggression in turn. Some U.S. analysts even advocate a competitive strategythat uses intermediate-range missiles to threaten Chinas interior to force Beijing to divert significant military resources to defending its homeland. Chinese observers would assess such a policy as a deliberate offensive threat, one that would trigger escalating reactions from Beijing.

With the United States and China on the verge of a new major power competition, the most urgent task for officials and experts on both sides is to find ways to manage existing perceptions of rising tensions and to prevent them from causing a crisis. China sees its regional missiles as instruments to counter aggressive U.S. power projection toward its own coast and to deter foreign intervention in its defense of territorial integrity. For its part, the United States seeks to address the growing vulnerability of its forward-based military assets and alliances. In this sense, both countries are on the defensive. However, the two governments disagree about what constitutes each others legitimate security interests in theregion and what means are justified to safeguard these interests in the future. This is a deeper political problem that can only be mitigated by developing more nuanced understandings of and empathy for each others thinking. Tougher military postures and more advanced military capabilities only contribute to negativity about each others intentions.

Neither country in any meaningful sense would winwhat could become an exceedingly expensive arms race. There is a need for new kinds of cooperative security measures to improve military stability and predictabilityas well asto dampen arms race dynamicsand strategic competition. There is deep skepticism of arms control in China, which matches that of some actors in Washington. One view often heard in Beijing is that other big powers merely pay lip service to arms control and, in the case of the INF Treaty, both Russia and the United States have secretly prepared for a way out for a long time. Many Chinese strategists believe that arms control is a game of power politics rather than a useful tool to manage strategic competition. Such skepticism and cynicism toward arms control is a fundamental barrier to any effort to include China now in a multilateralizedarms control treaty.

With arms control now out of vogue in Washington, it is incumbent upon U.S. and Chinese experts to find different means to build common understanding abouthow to mitigate risks from gaps in the security perceptions and the worst-case assumptions driving major power competition. Building such common understandings takes time and is hard. Perhaps in Washington, it will be seen as easier to build new intermediate-range missiles for Asia than to bridge these gaps with Beijing. But such a step would erode whatever foundation is left for cooperative security in East Asia.

In sum, the U.S. government needs to think about the costs and benefits of withdrawing from the INF Treaty and of deploying new missiles on Chinas periphery. The next steps by Washington will significantly shape Chinas threat perception and counterstrategy, both in and beyond its immediate region. It could either accelerate or slow the descent of the two countries into a comprehensive military competition.

For China, the era of relying on the U.S.-Russia bilateral arms control structure is at its end. Previous arms control arrangements have constrained the United States and Russia, while allowing China to build up its own defenses unconstrained by such rules. As China becomes a top-tier military power, its fast-growing force projection capabilities will meet with increasing international pressure and resistance. It is time for Beijing to think strategically about how to best defend its long-term security interests sustainably: is pursuing cooperative arms control better than simply accumulating military power? As a rising power aspiring to shape international norms and principles, China can no longer follow the lead of others.It has to set an example that it wishes others to follow.
