Explanations:The question asks which of the given sites is not disputed between India and China. To understand this, it is essential to know the geographical and historical context of the India-China border disputes.
The India-China border dispute, also known as the Sino-Indian border dispute, is a territorial conflict between the two countries over several regions. The primary areas of contention are in the Himalayan region, including the Aksai Chin and Arunachal Pradesh. The disputed sites mentioned in the options are part of these broader regions.
Doklam, located in the Himalayan region, is a disputed area between India, China, and Bhutan. It has been the site of significant border tensions, particularly in 2017 when Chinese and Indian troops faced off there. The Doklam standoff highlighted the complex geopolitical relationships in the region, involving not just India and China but also Bhutan.
Galwan Valley is another disputed site located in the Ladakh region of India. It gained international attention in 2020 when a deadly clash between Indian and Chinese troops occurred there. This incident underscored the ongoing tensions and the potential for conflict in the disputed areas.
Depsang Plains, also in the Ladakh region, has been the site of several standoffs between Indian and Chinese troops. The most notable of these occurred in 2013 and 2014, where both sides engaged in military standoffs over the control of the area. Depsang Plains is part of the broader Aksai Chin region, which is claimed by both India and China.
Lipulekh Pass, on the other hand, is not a disputed site between India and China. It is a high-altitude mountain pass located in the Uttarakhand region of India. The pass is used as a trade route between India and Nepal, and it is not involved in the India-China border disputes. The confusion might arise because Lipulekh Pass is in a region that is geographically close to the disputed areas, but it is not itself a point of contention between India and China.
Understanding the specific nature of each site's dispute is crucial for comprehending the geopolitical dynamics in the region. The correct answer is Lipulekh Pass, as it is not a disputed site between India and China.
