Class: 12Subject: Political ScienceBook: Politics in India Since IndependenceChapter: 4Title: India’s External RelationsSession: 2026–27
India became independent in a difficult international context marked by the devastation of the Second World War, the onset of the Cold War and the division of the world into two blocs led by the USA and the USSR. To preserve its hard-earned sovereignty, protect territorial integrity and promote rapid economic development, India under Jawaharlal Nehru (who was his own Foreign Minister, 1946–1964) adopted the policy of non-alignment — staying away from both military blocs (NATO and the Warsaw Pact) while taking aid from both. India championed Afro-Asian unity (the Bandung Conference, 1955) and helped found the Non-Aligned Movement (Belgrade, 1961). Friendship with China, expressed in the Panchsheel agreement of 1954, broke down over Tibet and the boundary dispute, leading to the Chinese invasion of 1962. India also fought Pakistan in 1965 (Tashkent Agreement) and in 1971, which created Bangladesh (Shimla Agreement, 1972). The chapter ends with India’s first nuclear test of May 1974 and its independent stand against the ‘discriminatory’ NPT.
Key Terms & Concepts
Non-alignment: India’s policy of not joining either of the two Cold War military blocs (the US-led and the Soviet-led) while maintaining friendly relations with all countries and taking independent positions on world issues.
Afro-Asian unity: Nehru’s effort to build solidarity among the newly independent nations of Asia and Africa — seen in the Asian Relations Conference (1947) and the Bandung Conference (1955).
Bandung Conference (1955): the Afro-Asian conference held in Bandung, Indonesia; it marked the zenith of India’s engagement with newly independent nations and led to the establishment of the NAM.
Non-Aligned Movement (NAM): a grouping of non-aligned nations; its first summit was held in Belgrade in September 1961, with Nehru as a co-founder.
Panchsheel: the Five Principles of Peaceful Coexistence, jointly declared by Nehru and Chinese Premier Zhou Enlai on 29 April 1954 to guide India–China relations.
Tibet question: China took control of Tibet in 1950; India conceded China’s claim under Panchsheel, but tension rose when the Dalai Lama was granted asylum in India in 1959.
1962 War: China’s invasion in October 1962 over the disputed Aksai-chin (Ladakh) and the eastern (NEFA / Arunachal Pradesh) borders; it dented India’s image and damaged Nehru’s stature.
Indus Waters Treaty (1960): a river-water sharing agreement signed by Nehru and General Ayub Khan, mediated by the World Bank, which has worked well despite Indo-Pak tensions.
1965 War: conflict with Pakistan under PM Lal Bahadur Shastri, ended by the Tashkent Agreement (January 1966) brokered by the Soviet Union.
Bangladesh war (1971): following Pakistan’s crackdown in East Pakistan and a refugee influx, India signed a 20-year Treaty of Peace and Friendship with the USSR (August 1971) and won the December 1971 war, creating Bangladesh; the Shimla Agreement followed in 1972.
Nuclear policy: India’s programme began in the late 1940s under Homi J. Bhabha; India conducted its first ‘peaceful’ nuclear explosion in May 1974 and refused to sign the NPT (1968), which it considered discriminatory.
NCERT Exercise — Full Solutions
All questions below are reproduced verbatim from the NCERT textbook’s end-of-chapter Exercises. Answers are original, written in exam-ready style.
1. Write ‘true’ or ‘false’ against each of these statements.
(a) Non-alignment allowed India to gain assistance both from USA and USSR.(b) India’s relationship with her neighbours has been strained from the beginning.(c) The cold war has affected the relationship between India and Pakistan.(d) The treaty of Peace and Friendship in 1971 was the result of India’s closeness to USA.
ANSWER(a) True. By staying out of both military blocs, India could secure aid and assistance from members of both the US-led and the Soviet-led camps.(b) False. India did not have strained relations with every neighbour from the start — for example, it began its relationship with China on a very friendly note and was among the first to recognise the communist government in 1949.(c) True. Pakistan joined the US-led military alliances during the Cold War and became a critical factor in India’s relations with the US and China, so the Cold War rivalry did affect Indo-Pak ties.(d) False. The 1971 Treaty of Peace and Friendship was signed with the Soviet Union, to counter the US–Pakistan–China axis; it reflected India’s closeness to the USSR, not the USA.
2. Match the following
(a) The goal of India’s foreign policy in the period 1950–1964(b) Panchsheel(c) Bandung Conference(d) Dalai Lamai. Tibetan spiritual leader who crossed over to Indiaii. Preservation of territorial integrity, sovereignty and economic developmentiii. Five principles of peaceful coexistenceiv. Led to the establishment of NAM
ANSWER(a) – ii. Preservation of territorial integrity, sovereignty and economic development.(b) – iii. Five principles of peaceful coexistence.(c) – iv. Led to the establishment of NAM.(d) – i. Tibetan spiritual leader who crossed over to India.
3. Why did Nehru regard conduct of foreign relations as an essential indicator of independence? State any two reasons with examples to support your reading.
ANSWERFor Nehru, the very test of independence was that a nation conducts its own foreign relations; he argued that the moment foreign relations ‘go out of your hands into the charge of somebody else’, you cease to be truly independent and are left only with ‘local autonomy’.Reason 1 – Sovereignty in decision-making. A free nation must take independent stands on world affairs. India did this by adopting non-alignment and refusing to join either bloc — for example, leading the world protest when Britain attacked Egypt over Suez in 1956, while choosing its own response to other crises.Reason 2 – Protecting national interest. Foreign policy was the means to safeguard sovereignty, territorial integrity and economic development. India recognised the communist government of China, championed decolonisation and Afro-Asian unity (Bandung, 1955) and helped found the NAM — all decisions taken in India’s own interest, showing that genuine independence means shaping one’s external relations oneself.
4. “The conduct of foreign affairs is an outcome of a two-way interaction between domestic compulsions and prevailing international climate”. Take one example from India’s external relations in the 1960s to substantiate your answer.
ANSWERForeign policy is shaped both by what happens inside a country and by the international situation. The Bangladesh crisis and the 1971 war illustrate this two-way interaction well (and the same logic applies to the 1971 Indo-Soviet Treaty).Domestic compulsion: the arrival of about 80 lakh refugees from East Pakistan placed an enormous economic and social burden on India, creating strong internal pressure to act.International climate: the US–China rapprochement and the US–Pakistan–China axis (Kissinger’s secret visit to China via Pakistan in July 1971) isolated India. To counter this, India signed the 20-year Treaty of Peace and Friendship with the Soviet Union in August 1971, which assured Soviet support. India’s decisive action in the December 1971 war — ending in the creation of Bangladesh — thus flowed from both domestic pressure and the prevailing international alignment.
5. Identify any two aspects of India’s foreign policy that you would like to retain and two that you would like to change, if you were to become a decision maker. Give reasons to support your position.
ANSWERThis is an opinion-based question; a well-reasoned answer is expected. A model response:Two aspects to retain: (i) The spirit of non-alignment / strategic autonomy — taking independent positions in the national interest rather than blindly following any power bloc keeps our sovereignty intact. (ii) Commitment to world peace and the peaceful settlement of disputes — reflected in Article 51 and India’s contribution to UN peacekeeping, this earns India moral standing and stability in its neighbourhood.Two aspects to change: (i) The earlier naive trust in neighbours’ intentions — the lack of military preparedness exposed in 1962 shows the need to combine friendship with strong, realistic defence. (ii) The limited economic engagement with the outside world caused by an inward-looking import-substitution strategy — greater trade and economic cooperation would strengthen India’s power and influence. (Other reasoned choices are also acceptable.)
6. Write short notes on the following.
(a) India’s Nuclear policy(b) Consensus in foreign policy matters
ANSWER(a) India’s Nuclear policy: India’s nuclear programme began in the late 1940s under the guidance of Homi J. Bhabha, aimed at generating atomic energy for peaceful purposes. Nehru was opposed to nuclear weapons and pleaded with the superpowers for comprehensive disarmament. When China tested nuclear weapons in 1964, the five nuclear powers tried to impose the Nuclear Non-proliferation Treaty (NPT) of 1968; India refused to sign it as discriminatory, since it legitimised the monopoly of the five nuclear-weapon states. India conducted its first nuclear test in May 1974, terming it a ‘peaceful explosion’. It later conducted tests in May 1998 and follows a doctrine of credible minimum nuclear deterrence with a ‘no first use’ policy, while seeking universal, non-discriminatory disarmament.(b) Consensus in foreign policy matters: Although political parties in India have minor differences about how to conduct external relations, Indian politics is generally marked by a broad agreement on national integration, the protection of international boundaries and questions of national interest. Because of this consensus, foreign policy has played only a limited role in party politics — even during the three wars of 1962–1971 and later, when different parties came to power, the basic direction of foreign policy remained largely unchanged.
7. India’s foreign policy was built around the principles of peace and cooperation. But India fought three wars in a space of ten years between 1962 and 1971. Would you say that this was a failure of the foreign policy? Or would you say that this was a result of international situation? Give reasons to support your answer.
ANSWERThe three wars were not primarily a failure of India’s foreign policy but largely the result of the international situation and the actions of its neighbours, though some lessons about preparedness must be admitted.Result of the international situation: The 1962 war was launched by China, which rejected the colonial boundary and invaded the disputed regions; India was the victim of aggression, not the initiator. The 1965 and 1971 wars were started by Pakistan’s attacks — in the Rann of Kutch and Kashmir in 1965, and the crackdown in East Pakistan that forced 80 lakh refugees into India in 1971. The Cold War rivalry and the US–Pakistan–China axis further shaped these conflicts.Some shortcomings: The 1962 reverse did expose Nehru’s naive assessment of Chinese intentions and India’s lack of military preparedness. Yet India did not abandon its commitment to peace — it accepted UN intervention, signed the Tashkent and Shimla agreements, and declared a unilateral ceasefire in 1971. So the wars reflect a hostile external environment rather than a collapse of India’s peace-oriented foreign policy.
8. Does India’s foreign policy reflect her desire to be an important regional power? Argue your case with the Bangladesh war of 1971 as an example.
ANSWERYes, India’s foreign policy has reflected a desire to be an important regional power, and the Bangladesh war of 1971 demonstrates this clearly.When Pakistan unleashed a reign of terror in East Pakistan, India extended moral and material support to the freedom struggle of Bangladesh and bore the burden of about 80 lakh refugees. To secure its position, India signed the 20-year Treaty of Peace and Friendship with the Soviet Union in August 1971, countering the US–Pakistan–China axis.In the December 1971 war, India used its air force, navy and army on both fronts; within ten days its army surrounded Dhaka and the Pakistani army of about 90,000 had to surrender — the largest military surrender since the Second World War. India then declared a unilateral ceasefire and signed the Shimla Agreement (1972). This decisive victory created a new nation, established India’s military prowess and demonstrated its ability to shape the politics of South Asia — a clear sign of India’s standing as the dominant regional power.
9. How does political leadership of a nation affect its foreign policy? Explain this with the help of examples from India’s foreign policy.
ANSWERThe personality, vision and judgement of a nation’s leaders strongly influence its foreign policy, as India’s experience shows.Nehru’s leadership (1946–1964): As both Prime Minister and Foreign Minister, Nehru personally shaped India’s foreign policy. His vision gave India the strategy of non-alignment, the championing of Afro-Asian unity and the NAM, Panchsheel with China and friendship with the USSR. At the same time, his trust in Chinese goodwill contributed to the unpreparedness exposed in the 1962 war, showing how a leader’s judgement can shape outcomes for better or worse.Other leaders: Lal Bahadur Shastri ordered a firm counter-offensive on the Punjab border in the 1965 war and signed the Tashkent Agreement. Indira Gandhi’s decisive leadership in 1971 created Bangladesh and led to the Shimla Agreement. Later leaders — from the Janata government’s ‘genuine non-alignment’ to the post-1990 tilt towards the US — each adjusted foreign policy according to their outlook, proving that leadership matters greatly even within a broad national consensus.
10. Read this passage and answer the questions below:
“Broadly, non-alignment means not tying yourself off with military blocs….It means trying to view things, as far as possible, not from the military point of view, though that has to come in sometimes, but independently, and trying to maintain friendly relations with all countries.” — Jawaharlal Nehru(a) Why does Nehru want to keep off military blocs?(b) Do you think that the Indo-Soviet friendship treaty violated the principle of non-alignment? Give reasons for your answer.(c) If there were no military blocs, do you think non-alignment would have been unnecessary?
ANSWER(a) Nehru wanted to keep off military blocs so that India could preserve its independence of judgement and view world issues on their merits rather than from a military point of view dictated by a superpower. Joining a bloc would have compromised India’s sovereignty, drawn it into the dangerous Cold War rivalry, and prevented it from maintaining friendly relations with all countries and obtaining aid from both sides.(b) No, the Indo-Soviet Treaty of 1971 did not violate non-alignment. It was a treaty of peace and friendship, not a military alliance binding India to a bloc. India signed it as a defensive, practical response to the US–Pakistan–China axis that had formed against it during the Bangladesh crisis. Non-alignment never meant isolation or equal distance from everyone; it meant taking independent decisions in the national interest — which is exactly what India did. India continued to act independently afterwards.(c) Even without military blocs, non-alignment would not have been entirely unnecessary, though its meaning would change. The core idea — independence of judgement and friendly relations with all nations — would still be valuable for a developing country seeking peace and development. However, the specific need to stay out of rival military blocs would disappear, so non-alignment would become a broader principle of strategic autonomy rather than a strategy of avoiding two camps.
Extra Practice Questions
Short Answer Type Questions
Q1. What were the three major objectives of Nehru’s foreign policy?
ANSWERThe three major objectives of Nehru’s foreign policy were to preserve the hard-earned sovereignty, to protect territorial integrity, and to promote rapid economic development. Nehru wished to achieve all three through the strategy of non-alignment.
Q2. What is Panchsheel? When and by whom was it declared?
ANSWERPanchsheel means the Five Principles of Peaceful Coexistence. It was jointly declared by the Indian Prime Minister Jawaharlal Nehru and the Chinese Premier Zhou Enlai on 29 April 1954, as a step towards a stronger and friendlier relationship between India and China.
Q3. Why did India refuse to sign the NPT of 1968?
ANSWERIndia considered the Nuclear Non-proliferation Treaty (NPT) of 1968 to be discriminatory, because it was selectively applicable to the non-nuclear powers and legitimised the monopoly of the five nuclear-weapon powers. India therefore refused to sign it and also opposed the CTBT.
Q4. What was the Tashkent Agreement?
ANSWERThe Tashkent Agreement was signed in January 1966 between Indian Prime Minister Lal Bahadur Shastri and Pakistan’s General Ayub Khan to end the 1965 war. It was brokered by the Soviet Union and restored peace between the two countries after the hostilities ended with UN intervention.
Q5. Why is the Bandung Conference important in India’s foreign policy?
ANSWERThe Afro-Asian conference held in Bandung, Indonesia, in 1955 marked the zenith of India’s engagement with the newly independent Asian and African nations. It promoted Afro-Asian unity and decolonisation and later led to the establishment of the Non-Aligned Movement, whose first summit was held in Belgrade in 1961.
Long Answer Type Questions
Q1. Explain the causes and consequences of the 1962 war between India and China.
ANSWERCauses: Two developments strained India–China relations. First, China annexed Tibet in 1950, removing a historical buffer; tension grew as China suppressed Tibetan culture and the Dalai Lama obtained asylum in India in 1959, which China alleged was anti-China activity. Second, a boundary dispute surfaced over the western sector (Aksai-chin in Ladakh) and the eastern sector (much of Arunachal Pradesh, then NEFA). Between 1957 and 1959 China occupied Aksai-chin and built a strategic road there; despite long correspondence, the differences could not be resolved. In October 1962, while the world’s attention was on the Cuban Missile crisis, China launched a swift, massive invasion. Consequences: Chinese forces captured key areas in Arunachal Pradesh before declaring a unilateral ceasefire and withdrawing. The war dented India’s image at home and abroad; India had to seek military help from the US and Britain while the USSR stayed neutral. It induced national humiliation but also strengthened nationalism, led to Defence Minister V. Krishna Menon leaving the cabinet, damaged Nehru’s stature, prompted the first no-confidence motion against his government, and triggered the reorganisation of the Northeast and a split in the CPI in 1964.
Q2. Describe the events leading to the 1971 Bangladesh war and its outcome.
ANSWERIn 1970, Pakistan’s first general election produced a split verdict: Bhutto’s party won in West Pakistan while Sheikh Mujib-ur Rahman’s Awami League swept East Pakistan. The West-Pakistani rulers refused to accept this democratic verdict or the demand for a federation. In early 1971 the Pakistani army arrested Sheikh Mujib and unleashed a reign of terror in East Pakistan, sparking a struggle to liberate ‘Bangladesh’. About 80 lakh refugees fled into India, which extended moral and material support to the freedom struggle. With the US and China backing Pakistan (Kissinger’s secret visit to China via Pakistan in July 1971), India signed a 20-year Treaty of Peace and Friendship with the Soviet Union in August 1971. A full-scale war broke out in December 1971; India retaliated with its air force, navy and army on both fronts, surrounded Dhaka within ten days, and the Pakistani army of about 90,000 surrendered. India declared a unilateral ceasefire; Bangladesh became free, and the Shimla Agreement between Indira Gandhi and Zulfikar Ali Bhutto (3 July 1972) formalised the return of peace. The victory caused national jubilation and boosted India’s standing as a regional power.
Q3. Why did India adopt the policy of non-alignment, and how successful was it?
ANSWERIndia adopted non-alignment because it gained independence just as the Cold War divided the world into two blocs led by the US and the USSR. To preserve sovereignty, protect territorial integrity and promote economic development, Nehru chose to stay away from both military alliances — NATO and the Warsaw Pact — while keeping friendly relations with all and reducing Cold War tensions. India advocated this approach as the ideal foreign policy, contributed to UN peacekeeping, and helped found the NAM in 1961. Successes: India retained independence of judgement — leading the protest against the 1956 Anglo-French attack on Egypt while taking its own line on Hungary — and obtained aid from both blocs. It became a respected moral voice among newly independent nations. Limits: non-alignment was a difficult balancing act and the balance did not always look perfect; it could not prevent the wars of 1962, 1965 and 1971, and at times (as with the 1971 Soviet treaty) India tilted towards one power. On the whole, however, non-alignment served India’s core interests well in a hostile international environment.

Exam Tips & Common Mistakes
How to score full marks in this chapter
Memorise the key dates and agreements accurately: Panchsheel (1954), Bandung (1955), Indus Waters Treaty (1960), NAM Belgrade summit (1961), the 1962 China war, Tashkent (1966), the Indo-Soviet Treaty (1971), Shimla (1972) and the first nuclear test (May 1974). For analytical questions, always present both sides — e.g. show how the wars were largely a result of the international situation while admitting the lessons of 1962. Link non-alignment to its three objectives (sovereignty, territorial integrity, economic development) and quote examples like Suez (1956) to prove India’s independent stand.
Common mistakes to avoid
Saying the 1971 Treaty of Peace and Friendship was signed with the USA — it was with the Soviet Union.
Confusing the leaders of the three wars: 1962 (Nehru), 1965 (Shastri), 1971 (Indira Gandhi).
Treating non-alignment as ‘neutrality’ or ‘isolation’ — it meant independent judgement, not staying away from all relations.
Mixing up the agreements: Tashkent ended the 1965 war; Shimla followed the 1971 war.
Forgetting that India recognised communist China in 1949 and began on a friendly note before the breakdown over Tibet and the border.
Writing the wrong year for India’s first nuclear test — it was May 1974 (1998 was the later series of tests).
Frequently Asked Questions
What is Chapter 4 of Class 12 Political Science (Politics in India Since Independence) about?
Chapter 4, India’s External Relations, explains how India shaped its foreign policy after Independence through non-alignment under Nehru, the ideals of Panchsheel and Afro-Asian unity, the three wars with China (1962) and Pakistan (1965 and 1971), and the evolution of India’s nuclear policy up to the first nuclear test of May 1974.
What is the policy of non-alignment?
Non-alignment was India’s policy of not joining either of the two Cold War military blocs led by the USA and the USSR, while keeping friendly relations with all countries, taking independent positions on world issues, and obtaining aid from both sides. India helped found the Non-Aligned Movement at Belgrade in 1961.
Why did India and China go to war in 1962?
Relations broke down over Tibet (annexed by China in 1950, with the Dalai Lama granted asylum in India in 1959) and a boundary dispute over Aksai-chin in Ladakh and the eastern sector (NEFA / Arunachal Pradesh). China launched a massive invasion in October 1962, captured key areas, then declared a unilateral ceasefire and withdrew.
