Geopolitical Analysis of India’s International Boundary Disputes and Peaceful Borders (Post-1947 Partition Era)
A comparative study of India's boundaries reveals a wide spectrum of relationships, ranging from complete tranquility with its Himalayan neighbor to enduring conflict shaped by historical partitions.
The vast network of India's borders provides a critical lens through which to view its foreign policy and security challenges, impacting regional stability and internal governance.
- (i) The borders define India's geographical and political limits, influencing its trade, defense strategy, and cultural exchanges with adjacent nations.
- (ii) Historical events, primarily the Partition of 1947, have indelibly marked certain boundaries, leading to persistent, internationally recognized disputes.
- (iii) The concept of boundary demarcation often rests on varying interpretations of colonial-era agreements or the realities established through military control.

Indo-Pakistan Boundary: The Legacy of the Radcliffe Award
The boundary separating India and Pakistan is a volatile frontier, a direct outcome of the hurried and arbitrary nature of the , leading to enduring territorial conflicts.
Origins of the Indo-Pak Border: The Radcliffe Line
The line was officially designated under the Radcliffe Award, named after its chairman, Sir Cyril Radcliffe, who was tasked with dividing millions based on religious majority. This poorly demarcated line instantly created complex issues, particularly in regions where populations were mixed, leading to the major disputed regions that persist today.
- (i) Key conflict areas include Jammu and Kashmir and the maritime-related swampy area of Sir Creek.
- (ii) The boundary has been the site of multiple wars and continuous military engagement since its inception in .

Major Disputed Territories Along the India-Pakistan Border
Several critical territories remain points of intense geopolitical friction, underscoring the deep ideological and political differences between the two nuclear-armed states.
Overview of Key Disputed Zones:
- (i) Jammu and Kashmir (J&K), Pakistan-occupied Kashmir (PoK), and Gilgit Baltistan: This is the most complex dispute, involving vast tracts of land. India asserts that approximately 78,000 sq. km of its territory in Jammu and Kashmir is under the illegal and forcible occupation of Pakistan. Furthermore, a highly contentious point is the transfer of 5,180 sq. km in Pakistan Occupied Kashmir to China under the so-called Sino-Pakistan Boundary Agreement of 1963, which India views as an illegal cession.
- (ii) Siachen Glacier: This strategically vital area, located in the eastern Karakorams, lies just east of the Actual Ground Position Line (AGPL). Despite being a contested region, the entire Siachen Glacier and all its major passes have been under the administration of India since the successful Operation Meghdoot in , highlighting a crucial military advantage for India.

Sir Creek dispute - (iii) Saltoro Ridge: These mountains, a subrange of the Karakoram Heights, are positioned on the southwest side of the Siachen Glacier. The ridge is claimed by India as part of Jammu and Kashmir Union Territory and by Pakistan as part of Gilgit-Baltistan. Following the operation, India secured military control of the main peaks and passes, with Pakistani forces relegated to the glacial valleys to the west, establishing the current ground reality.
Sir Creek: The Coastal Demarcation Challenge
- (a) Sir Creek is a 96 km long strip of water running through the marshlands of the Rann of Kutch, representing a critical, unresolved maritime boundary issue.
- (b) The core disagreement stems from differing interpretations of the Bombay Government Resolution of 1914, with Pakistan claiming the eastern bank while India advocates for the internationally recognized thalweg doctrine (centerline rule).
- (c) Due to this fundamental disagreement, the International Boundary in the Sir Creek area and the International Maritime Boundary Line (IMBL) between the two nations remain officially undemarcated.
