Core Content

This testimony by James Schoff, Senior Associate of the Asia Program at the Carnegie Endowment for International Peace, discusses the evolving security dynamics in Northeast Asia and their implications for U.S. foreign policy. It highlights how the rise of China's military and economic power is prompting Japan and South Korea to reassess their security strategies and strengthen their alliances with the United States. The testimony emphasizes the need for the U.S. to balance reassurance with diplomacy to maintain stability in the region.

Main Views

Japan's Security Concerns and Posture

• Perceived Vulnerability: Japan feels increasingly vulnerable due to China's growing military capabilities and territorial claims in the East China Sea, particularly regarding the Senkaku Islands. It also faces economic dependence on China and environmental issues from Chinese pollution.
• Defense Budget: Japan's defense spending has been relatively flat since 2000, while China's military budget has grown by over 10% annually.
• Military Modernization: Japan is enhancing its intelligence, surveillance, and reconnaissance (ISR) capabilities, including UAVs, space-based assets, and cyber security. It is also acquiring amphibious vehicles, Osprey tilt-rotor aircraft, and upgrading its naval fleet.
• Collective Self-Defense: The Abe administration is pushing to allow Japan to exercise collective self-defense, which would permit military support to allies in case of an attack. This is seen as a way to deter China and enhance U.S.-Japan security cooperation.
• Legal and Constitutional Reforms: Japan is seeking to revise its constitution to allow more flexible military use, including the establishment of a Fundamental Law on National Security.
• Alliance Reforms: Japan is working with the U.S. to revise defense guidelines to improve interoperability and cooperation, particularly in intelligence, logistics, and maritime security.

South Korea's Security Concerns and Posture

• Focus on North Korea: South Korea's defense strategy is primarily driven by North Korean military threats, including nuclear and missile capabilities. It has increased its defense budget significantly since 2000, reaching nearly $32 billion in 2013.
• Military Modernization: South Korea has acquired Aegis-equipped destroyers, a larger submarine fleet, and AWACs aircraft. It is also expanding its missile range and investing in missile defense and UAVs.
• Alliance with the U.S.: South Korea maintains strong alliance ties with the U.S. and has developed a counter-provocation plan in response to North Korean aggression, in close coordination with Washington.
• Diplomatic Hedging: Seoul is pursuing improved relations with China to counterbalance U.S. influence and reduce reliance on Washington, particularly due to China's economic and political leverage over North Korea.
• Regional Cooperation: South Korea is participating in multilateral security initiatives, such as counterpiracy operations in the Gulf of Aden, and is open to broader regional security frameworks that include other partners like Australia and Southeast Asian nations.

Key Information

• U.S. Rebalance to Asia: The U.S. is seeking to strengthen its alliances in Asia to counter China's rise and maintain regional stability.
• Alliance Challenges: Both Japan and South Korea are concerned about the long-term sustainability of U.S. primacy in the region due to fiscal constraints and political issues in Washington.
• Defense Guideline Revisions: The U.S. and Japan are revising their defense guidelines to improve cooperation in intelligence, surveillance, and reconnaissance (ISR), logistics, and maritime security. This is the third major revision in over 50 years.
• Functional Approach: A capabilities-based (functional) approach to alliance cooperation is recommended, which focuses on enhancing interoperability and flexibility rather than specific missions or locations.
• Regional Security Architecture: The U.S. and its allies aim to build a more integrated regional security architecture that can include China and reduce security competition in East Asia.

Strategic Implications

• Deterrence and Reassurance: The U.S. must balance reassurance to its allies with deterrence against Chinese coercion, while avoiding the perception of subsidizing their security at unsustainable costs.
• Trilateral Cooperation: Strengthening U.S.-Japan-South Korea cooperation is crucial, particularly in addressing North Korean threats and managing security competition with China.
• Historical Sensitivities: The U.S. is wary of Japan's historical revisionism, which could strain relations with South Korea and China, and could hinder the effectiveness of the U.S.-Japan alliance.
• Regional Integration: A functional approach to defense cooperation could help integrate the U.S. with other regional partners, such as Australia and Southeast Asian countries, to build a more collective security framework.

Conclusion

The testimony underscores the need for the U.S. to adapt its security strategy in Northeast Asia by enhancing alliance cooperation, improving interoperability, and fostering a more collective regional security approach. This will require a shift from traditional hub-and-spoke alliances to more integrated and flexible security partnerships, while addressing the political and historical sensitivities that may affect such efforts.
