India-China dispute in Eastern Ladakh
Solution:
The dispute that escalated in 2025 due to increased military activities near the Line of Actual Control (LAC) is the India–China dispute in Eastern Ladakh.
Explanation:
The LAC serves as the de facto border between India and China. Even though disengagement efforts and patrolling agreements were initiated earlier, Eastern Ladakh remained a sensitive region in 2025, with continued military presence, infrastructure development, and strategic positioning by both sides.
Why other options are incorrect:
India–Pakistan (Siachen/Kashmir): This conflict occurs along the Line of Control (LoC) and Actual Ground Position Line (AGPL), not the LAC.
India–Nepal (Kalapani/Lipulekh): This is a territorial boundary dispute based on historical treaties, not related to the LAC.
India–Sri Lanka (Katchatheevu): This is a maritime dispute in the Palk Strait and has no connection with the LAC.
Correct Answer: India–China dispute in Eastern Ladakh
