The China-Russia Entente in East Asia

Contending with Authoritarian Partnership in a Critical Region

Executive Summary

Closer cooperation between China and Russia is a major force driving global geopolitics. But how relations between the two authoritarian powers are shaping specific regional and functional areas remains understudied. This report helps to fill that gap for the critical region of East Asia.

The China-Russia relationship has improved despite—and, in some ways, because of—Russia’s war in Ukraine. Beijing helps to fuel Russia’s war machine and defends the principles Moscow uses to justify the invasion. Both powers are also deepening and expanding their relationship beyond Ukraine. The pair cooperate across a range of fields, from military affairs to economics and global norms. Undoubtedly, current and potential fissures remain in the bilateral relationship. However, the leadership in both countries carefully manages these tensions to ensure they do not derail the overall relationship.

Beijing-Moscow coordination extends to East Asian hot spots, including the areas around Japan, the Korean Peninsula, Taiwan, and the South China Sea. Around Japan, China and Russia work together to advance their respective territorial claims and pressure a rival Northeast Asian power and close U.S. ally. China and Russia use multiple military tools in pursuit of those goals, including joint aerial and naval patrols, joint exercises, and incursions into Japan’s air defense identification zone. Together, these activities put significant operational strain on the Self-Defense Forces, Japan’s military, as they respond.

On the Korean Peninsula, China and Russia have turned away from multilateral cooperation to manage the North Korea threat and toward blaming democracies and reaching out to Pyongyang instead. Russia has moved closer to North Korea to help offset Moscow’s diplomatic isolation and barter for weapons. But that cooperation has not yet undermined China’s preferences or interests. Beijing maintains its own working relationship with Pyongyang while coordinating with Moscow to blunt international pressure on North Korea.

How China and Russia manage their relations in East Asia will be a major factor shaping the regional diplomatic and security environment.

To the south, Russia increasingly backs Beijing’s actions to pressure Taiwan as Taipei reaches out to democracies worldwide. Moscow’s support for Beijing has been particularly pronounced during major cross-Strait events in recent years. In the South China Sea, Russia tries to balance historical relationships with Southeast Asian states even as its power wanes and subservience to China deepens. For example, Russia’s cooperation on energy projects with Vietnam shows that Beijing’s and Moscow’s regional interests sometimes diverge.

How China and Russia manage their relations in East Asia will be a major factor shaping the regional diplomatic and security environment. Moscow’s presence and power in East Asia have already suffered because of its disastrous war in Ukraine. Over time, Russia likely will become even more subservient to China. The China-Russia entente might therefore prove most useful for Beijing in its home region.

To contend with these trends, U.S. and allied policymakers should adopt the following principles and recommendations:

  • Structure policies around the reality that Russia is no longer a geopolitical balancer in East Asia.
  • Identify and track metrics for the China-Russia partnership, including factors bringing them together and areas of tension.
  • Strengthen coalitions to counter the China-Russia entente in East Asia.
  • Expand discussions on extended deterrence and contingency planning to account for China-Russia collaboration.
  • Deepen security, diplomatic, and economic ties with nonaligned and loosely aligned countries in East Asia so they have alternatives to Russia and China.
  • Conduct principled diplomacy with Beijing and seek to keep lines of communication open with Moscow but keep expectations in check and allies informed.

Introduction

Closer cooperation between Beijing and Moscow is a trend that continues to shape global geopolitics. Analysis of this trend, however, tends to focus on assessing the general relationship without examining specifically how the People’s Republic of China (PRC) and Russia are working together in critical regional and functional areas. This report addresses the understudied question of how cooperation between China and Russia shapes East Asia. It focuses on the region’s most critical diplomatic and security issues rather than attempting an exhaustive analysis of these multifaceted relationships. The report proceeds in three parts. First, it considers the trajectory of China-Russia relations after more than two and a half years of war in Ukraine. Second, the paper assesses the dynamics of Beijing-Moscow cooperation across major regional flashpoints: the areas around Japan, the Korean Peninsula, Taiwan, and the South China Sea. Third, it provides recommendations for U.S. policymakers for how Washington and its allies and partners can counteract China-Russia cooperation where it undermines U.S. interests or values.

About the Indo-Pacific Program

The Center for a New American Security’s Indo-Pacific Security Program addresses opportunities and challenges for the United States in the region, with a growing focus on issues that originate in the Indo-Pacific but have global implications. It draws on a team with deep government and nongovernment expertise in regional studies, U.S. foreign policy, international security, and economic statecraft. The Indo-Pacific Security Program analyzes trends and generates practical and creative policy solutions around five main research priorities: U.S.-China strategic competition, India’s growing role in the Indo-Pacific, American alliances and partnerships, the North Korea threat, and challenges in South and Central Asia.
