India is furious over a new agreement between Pakistan and China to formalize their shared border in a mountainous area, including the Shaksgam Valley, which India considers its own. New Delhi views the 1963 cession of this land by Pakistan to China as illegal and asserts Pakistan has no right to make such agreements over disputed Indian territories.
Imagine three neighbors, India, Pakistan, and China, who share a mountain border. India and Pakistan have long disagreed about who owns a part of these mountains. Now, Pakistan and China have decided to draw a clear line on their shared border and work together there. India is very angry because it claims that mountain area is theirs, and Pakistan had no right to make deals about it. It's like two friends drawing a line on a shared toy that a third friend says is theirs.
Analysis
The recent formalization of the border between Pakistan and China in a contested Himalayan region has ignited a fierce diplomatic row with India, underscoring the intricate and volatile geopolitical landscape of South Asia. This agreement, which establishes a "Pakistan-China Joint Boundary Commission," is seen by Islamabad as a crucial step towards enhancing cooperation in border management, trade, and connectivity. However, New Delhi has vehemently rejected the accord, asserting its legal invalidity and claiming the territory as its own. The timing of this announcement is particularly sensitive, as India and China are simultaneously attempting to de-escalate military tensions along their own disputed Line of Actual Control, while Beijing and Islamabad deepen their strategic alignment in areas India also claims.
Shaksgam Valley
The core of India's grievance lies in the historical context of the Shaksgam Valley, an area spanning approximately 5,180 square kilometers. This valley was ceded by Pakistan to China in 1963, an act that India has consistently deemed illegal and without any legal basis. From India's perspective, the Shaksgam Valley is an integral part of its Ladakh territory, which was formerly part of the princely state of Jammu and Kashmir. India argues that Pakistan had no legitimate authority to transfer this land, as it was illegally occupied by Pakistan prior to the cession.
The Indian government has never recognized the 1963 agreement, considering it null and void. This long-standing position forms the bedrock of India's current strong reaction, emphasizing that Pakistan lacks any legal standing to enter into agreements concerning territories that India claims are illegally and forcibly under Pakistani occupation. The historical narrative of illegal occupation and subsequent cession without India's consent fuels the deep-seated resentment and explains the immediate and unequivocal rejection from New Delhi.
Randhir Jaiswal
The Indian Ministry of External Affairs, through its spokesperson Randhir Jaiswal, articulated India's firm stance, stating unequivocally, "There is no border between Pakistan and China. We reject this so-called joint commission, which has no legal basis." This statement underscores India's refusal to acknowledge any legitimacy in the border agreement, particularly as it pertains to land India considers sovereign. Jaiswal's remarks highlight India's consistent position that any such agreement involving disputed territories is inherently flawed and unacceptable.
This diplomatic protest comes at a delicate juncture for regional relations. India and China have been engaged in protracted efforts to stabilize their military standoff along the Line of Actual Control, following years of heightened tensions. Against this backdrop, the deepening cooperation between Beijing and Islamabad on a border that India also claims is perceived by New Delhi as a provocative move, further complicating the already strained trilateral dynamics and potentially undermining efforts towards regional stability.
Jabin T. Jacob
According to Jabin T. Jacob, a professor at Shiv Nadar University Delhi, this recent development is not an entirely new arrangement but rather a "revival of an old mechanism" stipulated in the original 1963 China-Pakistan agreement. Jacob suggests that the timing could be attributed to China's broader strategy to define and stabilize its borders, as well as a desire to formalize and institutionalize cross-border movements and exchanges, especially given the instability on Pakistan's other frontiers. This perspective frames the agreement as a logical, albeit delayed, implementation of a long-standing understanding between Pakistan and China.
However, Jacob also emphasizes that India should be "concerned," pointing out that the new action appears to disregard Article 6 of the 1963 agreement. This article reportedly stipulated that the border would be renegotiated after the final resolution of the Kashmir dispute. From India's viewpoint, this oversight, coupled with China's significant advantage in the global information space through state-backed media like CGTN and China Radio International, allows Beijing to effectively project its narrative internationally, potentially marginalizing India's protests in global capitals. This highlights a critical dimension of modern geopolitics, where control over information can significantly influence international perceptions and diplomatic outcomes, further exacerbating India's challenges in asserting its claims.
Key points
- Pakistan and China have formalized their border in a disputed Himalayan region, establishing a "Pakistan-China Joint Boundary Commission."
- India vehemently rejects this agreement, claiming the Shaksgam Valley (ceded by Pakistan to China in 1963) as its own territory in Ladakh.
- New Delhi asserts that Pakistan had no legal right to enter into agreements concerning Indian territories under its illegal occupation.
- The move comes amidst ongoing efforts to stabilize India-China relations along the Line of Actual Control, adding to regional tensions.
- Experts suggest the agreement is a revival of a 1963 mechanism, potentially disregarding a clause for renegotiation after the Kashmir dispute's resolution.
The establishment of a joint boundary commission could lead to more structured and peaceful management of the Pakistan-China border, potentially reducing localized skirmishes and facilitating legitimate trade and connectivity in the region. This formalization might bring a degree of predictability to this specific frontier, allowing for better infrastructure development like the China-Pakistan Economic Corridor.
This agreement is likely to significantly escalate tensions between India on one side, and Pakistan and China on the other, potentially leading to increased military posturing and diplomatic friction in the already volatile Himalayan region. India's strong rejection could hinder broader efforts to stabilize relations with China and further entrench the long-standing Kashmir dispute, making future resolutions more challenging.
