Southeast Asia has captivated the attention of global community over space and time as a geostrategically significant region. Which among the following is the most convincing explanation for this global perspective ?
Answer (d) & explanation
Option (d) is the most convincing (d). Southeast Asia lies between the Pacific and Indian Oceans, and sea lanes such as the Strait of Malacca, Sunda and Lombok carry a large share of world trade and energy. This lasting maritime character explains its importance 'over space and time'. (a) and (c) are wrong because they describe single periods, the Second World War and the Cold War. (b) is wrong because its position between China and India is only one, narrower angle, not the deepest reason.
Notice the present: the South China Sea disputes, ASEAN centrality and India's Act East and Indo-Pacific policies all flow from this maritime geography. Trap: options tied to one era cannot explain 'over space and time'.
(a) and (c) are true but belong to one period each; the question asks for a reason that holds "over space and time".
Answer as per the official UPSC answer key.
With reference to “Look East Policy” of India, consider the following statements :
- 1. India wants to establish itself as an important regional player in the East Asian affairs.
- 2. India wants to plug the vacuum created by the termination of Cold War.
- 3. India wants to restore the historical and cultural ties with its neighbours in Southeast and East Asia.
Which of the statements given above is/are correct ?
Answer (b) & explanation
Statements 1 and 3 are correct (b). The Look East Policy (1991, under P.V. Narasimha Rao) aimed to make India an important regional player in East and Southeast Asia through trade, investment and ties with ASEAN (1), and to revive old historical and cultural links of Buddhism, trade and Indian kingdoms (3). Statement 2 is wrong: the policy was driven by economic reform and the loss of the Soviet partner, not by a wish to 'fill a Cold War vacuum'. So (a), (c) and (d) fail.
Notice the upgrade: it became the Act East Policy in 2014, adding security, connectivity (Kaladan, India–Myanmar–Thailand highway) and the Indo-Pacific. India became an ASEAN dialogue partner in 1995 and a Comprehensive Strategic Partner in 2022.
Statement 2 sounds right because the policy began in 1991, just as the Cold War ended, but filling a "vacuum" was never its aim.
