Context: The Yoshida Doctrine enabled post-war Japan to rely on the US security umbrella while concentrating on economic recovery. Today, Japan faces a “China dilemma” because China is simultaneously its major economic partner and principal security concern. India faces a similar challenge. This creates the need for a Yoshida Doctrine 2.0 based on economic de-risking, deterrence and diversified partnerships.

Requirement of Yoshida Doctrine 2.0

1. China’s economic importance:
   China is deeply integrated into Japanese and Indian supply chains, making complete economic decoupling costly and impractical.
2. Growing security threat:
   Both India and Japan face concerns over China’s increasing military capabilities and unilateral attempts to alter the status quo, particularly in the Indo-Pacific.
3. Need to balance security and economic interests:
   The objective should be to de-risk from China without completely decoupling, while deterring aggression without provoking a wider conflict.
4. Need for strategic autonomy:
   Both countries need diversified partnerships so that they are not strategically dependent on either Washington or Beijing.

Three pillars of Yoshida Doctrine 2.0

1. Economic security and resilient supply chains

1. India and Japan should cooperate on critical minerals, semiconductors and resilient supply chains.
2. More than 1,400 Japanese firms operate in India, with around half engaged in manufacturing.
3. Japan’s proposed $61-billion investment over the next decade can strengthen India’s manufacturing base while providing Japanese companies an alternative to excessive dependence on China.
4. Bilateral trade should be progressively expanded towards $100 billion.

2. Defence technology and credible deterrence

1. Economic cooperation needs to be complemented by deployable security capabilities.
2. Japan has increased defence spending from 1% to around 2% of GDP, while India’s defence spending as a share of GDP has declined despite rising absolute expenditure.
3. Japan’s gradual relaxation of post-war arms export restrictions creates opportunities for deeper defence cooperation.
4. The proposed transfer and production of Mogami-class frigates under Make-in-India, along with BrahMos integration, can strengthen maritime capabilities.
5. Cooperation should particularly focus on underwater domain awareness, maritime ISR, unmanned systems, secure communications and anti-submarine warfare.

3. Joint outreach in West Asia

1. Both India and Japan are heavily dependent on imported hydrocarbons.
2. Cooperation in West Asia can therefore combine energy security with maritime security.
3. A joint framework for maritime security in West Asia would protect freedom of navigation while remaining relatively low-provocation and high-utility.

Major constraints

1. Economic interdependence with China:
   India-China trade reached $127.7 billion in FY 2024-25, while Japan-China trade was around $300 billion in 2024, showing that de-risking cannot simply mean economic separation.
2. Domestic political and institutional constraints:
   Japan faces pacifist sentiment and a risk-averse defence industry, while India has traditionally preferred outright defence purchases over co-development.
3. Currency vulnerabilities:
   Weakness of the yen and rupee increases the cost of imports, including defence equipment, and complicates strategic decision-making.
4. Implementation deficit:
   Despite strong political convergence, India and Japan have not yet translated their shared concerns regarding China into sufficiently deployable and deterrent capabilities.

Way forward

1. India and Japan should ring-fence strategic projects from routine procurement procedures.
2. Two or three flagship projects should be prioritised in areas such as underwater domain awareness, maritime ISR and secure communications.
3. Defence cooperation should move from buyer-seller relations towards co-development and co-production.
4. Economic diversification should focus on critical technologies and supply chains rather than complete decoupling from China.
5. Maritime cooperation should extend from the Indo-Pacific to West Asia, linking security with energy interests.

Conclusion: The original Yoshida Doctrine succeeded because Japan made a clear strategic choice and pursued it consistently for decades. A Yoshida Doctrine 2.0 should similarly combine economic growth with strategic resilience: de-risk from China without decoupling, deter aggression without provoking war, and diversify partnerships without becoming dependent on any single power. For India and Japan, the priority is therefore to move from shared anxiety to shared deterrent capability and from strategic rhetoric to implementation.

Question: India and Japan face a common strategic challenge from China while remaining economically interdependent with it. In this context, discuss the relevance of a “Yoshida Doctrine 2.0” for India-Japan relations.
