Introduction

India’s external relations post-independence were shaped by both domestic and international challenges. While internal politics focused on nation-building and economic development, external policies addressed global dynamics and regional conflicts. This chapter examines:

  • The international context shaping India’s foreign policy.
  • Operational principles guiding India’s foreign policy.
  • India’s relations with China and Pakistan.
  • The evolution of India’s nuclear policy.

India’s innovative response included the policy of non-alignment, but conflicts with neighbors led to wars in 1962, 1965, and 1971, influencing domestic politics.

International Context

Global Environment

  • Post-World War II: The world was recovering from a devastating war, focusing on reconstruction and establishing the United Nations (UN).
  • Decolonization: Many Asian and African nations gained independence, grappling with welfare and democracy.
  • Cold War: The US and Soviet Union led opposing blocs, dividing the world into two camps (NATO vs. Warsaw Pact).
  • Challenges for Developing Nations: Limited resources led to modest foreign policy goals, focusing on peace and regional development, often influenced by aid from powerful states.

India’s Specific Context

  • British Legacy: Left international disputes, such as those over Jammu and Kashmir.
  • Partition: Created tensions with Pakistan, complicating regional relations.
  • Poverty Alleviation: Domestic priority of economic development influenced foreign policy to prioritize peace and sovereignty.

India’s Foreign Policy Goals

  • Respect sovereignty of all nations.
  • Achieve security through peace, as reflected in the Directive Principles of State Policy (Article 51).

Constitutional Principles

  • Article 51 (Directive Principles): Guides India’s foreign policy to:
    • Promote international peace and security.
    • Maintain just and honorable relations between nations.
    • Foster respect for international law and treaties.
    • Encourage dispute settlement through arbitration.
  • Assessment (1950s-1960s): India largely adhered to these principles through non-alignment, though wars with China (1962) and Pakistan (1965, 1971) challenged the peace objective.

Policy of Non-Alignment

Historical Roots

  • India’s national movement was part of a global anti-colonial struggle, influencing liberation movements in Asia and Africa.
  • Contacts with other colonies and the formation of the Indian National Army (INA) by Subhash Chandra Bose highlighted global linkages.

Nehru’s Vision

  • Role: As Prime Minister and Foreign Minister (1946-1964), Jawaharlal Nehru shaped India’s foreign policy.
  • Objectives:
    • Preserve sovereignty.
    • Protect territorial integrity.
    • Promote economic development.
  • Strategy: Non-alignment, avoiding military alliances (NATO, Warsaw Pact) to maintain independence.
  • Quote:
    “Our general policy is to avoid entanglement in power politics and not to join any group of powers as against any other group.” – Nehru, 1947

Challenges and Balancing Act

  • Domestic Opposition: Leaders like Ambedkar and parties like Bharatiya Jan Sangh and Swatantra Party favored alignment with the US, viewing it as pro-democracy.
  • International Perception: The US resented India’s non-alignment and growing Soviet ties, leading to strained Indo-US relations in the 1950s.
  • Examples of Non-Alignment:
    • Suez Crisis (1956): India led global protests against Britain’s attack on Egypt, opposing neo-colonialism.
    • Hungary Invasion (1956): India avoided public condemnation of the Soviet invasion, showing a nuanced stance.
  • Success: India maintained an independent stance, gaining aid from both blocs, though the balance was imperfect.

Economic Context

  • India’s import-substitution strategy limited economic interactions with the world, reinforcing non-alignment’s focus on self-reliance.

Afro-Asian Unity

  • Nehru’s Advocacy: Promoted Asian unity in the 1940s-1950s, envisioning India as a leader in Asia and Africa.
  • Key Events:
    • Asian Relations Conference (1947): Held in Delhi, five months before independence, to foster Asian solidarity.
    • Indonesia Support (1949): India convened a conference to support Indonesia’s freedom from Dutch rule.
    • Bandung Conference (1955): In Indonesia, marked the peak of India’s engagement with newly independent nations, leading to the Non-Aligned Movement (NAM).
    • NAM First Summit (1961): Held in Belgrade, with Nehru as a co-founder.
  • Other Contributions: India opposed apartheid in South Africa and supported decolonization globally.

Relations with China

Initial Friendship

  • Post-1949: India recognized Communist China early, supporting it in international forums.
  • Panchsheel (1954): Nehru and Zhou Enlai signed the Five Principles of Peaceful Coexistence, strengthening ties.
  • Concerns: Vallabhbhai Patel warned of potential Chinese aggression, but Nehru deemed it unlikely, relying on para-military border forces.

Tibet Issue

  • Background: China annexed Tibet in 1950, removing a historical buffer. India initially accepted China’s claim in the Panchsheel agreement.
  • Tensions:
    • India grew uneasy over Tibet’s cultural suppression.
    • In 1958, an armed uprising in Tibet was crushed by China.
    • In 1959, the Dalai Lama sought asylum in India, granted by Nehru, prompting Chinese protests.
  • Impact: Strained relations, with India hosting Tibetan refugees (e.g., in Dharamshala) and supporting Tibet’s cause domestically (e.g., Socialist Party, Jan Sangh).

Border Dispute and 1962 War

  • Dispute:
    • Western End: Aksai Chin (Ladakh).
    • Eastern End: Arunachal Pradesh (NEFA).
    • India cited colonial-era boundaries; China rejected them.
    • China occupied Aksai Chin (1957-1959) and built a road, escalating tensions.
  • 1962 Invasion:
    • China launched a massive attack in October 1962, capturing areas in Arunachal Pradesh and advancing in Ladakh.
    • After two waves, China declared a unilateral ceasefire and withdrew.
  • Consequences:
    • Domestic: National humiliation, criticism of Nehru’s naivety, and V. Krishna Menon’s resignation. A no-confidence motion was debated in Lok Sabha.
    • International: India sought US and UK military aid; the Soviet Union remained neutral.
    • Political: Congress lost by-elections, and the CPI split into CPI (pro-USSR) and CPI-M (pro-China) in 1964.
    • Northeast: Prompted reorganization, with Nagaland gaining statehood and Manipur/Tripura getting legislative assemblies.

Post-1962 Relations

  • Diplomatic relations resumed in 1976, with visits by Vajpayee (1979) and Rajiv Gandhi (1988).
  • Focus shifted to trade, though border issues persist.

Relations with Pakistan

Early Conflicts

  • Kashmir Dispute (1947): A proxy war in Jammu and Kashmir was referred to the UN, avoiding a full-scale war.
  • Cooperation:
    • Restoration of abducted women post-Partition.
    • Indus Waters Treaty (1960): Mediated by the World Bank, resolved river-sharing disputes, remaining effective despite tensions.

1965 War

  • Context: Under PM Lal Bahadur Shastri, Pakistan attacked Rann of Kutch (April) and Jammu and Kashmir (August-September 1965), expecting local support that didn’t materialize.
  • Indian Response: Counter-offensive on the Punjab border, reaching near Lahore.
  • Outcome: UN-brokered ceasefire; Tashkent Agreement (1966) signed by Shastri and Ayub Khan, restoring peace but straining India’s economy.

Bangladesh War (1971)

  • Background:
    • Pakistan’s 1970 elections resulted in a split: Bhutto won in West Pakistan, Awami League (Sheikh Mujib) in East Pakistan.
    • Pakistani rulers rejected the verdict, arresting Mujib and unleashing violence in East Pakistan.
  • India’s Role:
    • Hosted 8 million East Pakistani refugees.
    • Supported Bangladesh’s liberation movement morally and materially.
  • Geopolitics:
    • US and China supported Pakistan; India signed a 20-year Treaty of Peace and Friendship with the USSR (1971) for support.
  • War:
    • December 1971: Pakistan attacked Punjab, Rajasthan, and Jammu and Kashmir; India retaliated on both fronts.
    • Indian army, supported by locals, surrounded Dhaka; 90,000 Pakistani troops surrendered.
  • Outcome:
    • Bangladesh emerged as a free nation.
    • Shimla Agreement (1972) signed by Indira Gandhi and Bhutto formalized peace.
    • Boosted Indira Gandhi’s popularity and Congress’s electoral success.

Kargil Conflict (1999)

  • Pakistani forces (claiming to be Mujahideen) occupied Indian posts along the Line of Control (LoC).
  • India regained control by July 1999, amid global attention due to both nations’ nuclear capabilities.
  • In Pakistan, the conflict led to a military coup by General Pervez Musharraf.

Post-1971 Relations

  • Efforts to normalize relations included cultural exchanges, bus/train services, and economic cooperation.
  • Kashmir remains a core issue, with intermittent peace efforts.

Short Answer Questions

  • 3. Why Nehru regarded foreign relations as an indicator of independence?
    • Reason 1: Sovereignty: Independent foreign policy demonstrated India’s freedom from colonial control. E.g., Non-alignment avoided superpower influence.
    • Reason 2: Global Role: Active participation in world affairs (e.g., Bandung Conference) showcased India’s agency as a new nation.
  • 4. Two-way interaction in foreign policy (1960s example):
    • Example: 1962 China War. Domestic: Lack of military preparedness reflected resource constraints. International: Cold War dynamics and China’s aggression shaped the conflict, forcing India to seek US/UK aid.
  • 5. Aspects to retain/change in foreign policy:
    • Retain:
      • Non-alignment: Maintains strategic autonomy in a multipolar world.
      • Support for decolonization: Upholds India’s moral stance globally.
    • Change:
      • Pro-US tilt: Balance with other powers (e.g., Russia, China) for broader partnerships.
      • Reactive defense policy: Strengthen proactive military modernization to deter conflicts.
  • 6. Short notes:
    • India’s Nuclear Policy: Initiated for peaceful purposes under Nehru and Bhabha. Rejected NPT (1968) as discriminatory. Conducted “peaceful” test (1974) and military tests (1998). Adopts “no first use” and credible minimum deterrence, advocating global disarmament.
    • Consensus in Foreign Policy: Indian parties broadly agree on national integration, border protection, and national interest. Despite wars (1962-1971), foreign policy rarely divides parties, reflecting unity on core issues.
  • 7. Wars (1962-1971) as a failure of foreign policy or international situation?
    • International Situation:
      • 1962: China’s aggression and Cold War dynamics (US-Soviet rivalry) overwhelmed India’s unpreparedness.
      • 1965: Pakistan’s miscalculation and Cold War alliances (US support for Pakistan) escalated tensions.
      • 1971: Pakistan’s internal crisis and US-China support forced India’s intervention.
    • Partial Failure: Nehru’s naive trust in China (1962) and delayed military modernization were lapses, but non-alignment itself was not flawed.
  • 8. India as a regional power (Bangladesh War):
    • Evidence: India’s decisive intervention, supporting Bangladesh’s liberation, showcased military prowess and regional influence. The USSR treaty countered US-China support for Pakistan, affirming India’s strategic autonomy. The war’s success boosted India’s image as a regional leader.
  • 9. Political leadership’s impact on foreign policy:
    • Nehru: Non-alignment and Afro-Asian unity reflected his anti-colonial vision (e.g., Bandung Conference).
    • Indira Gandhi: Pragmatic leadership in 1971 war and 1974 nuclear test showed assertive nationalism, balancing domestic and international pressures.
