evidence: In 1963, Pakistan illegally gifted the Shaksgam valley to China under the China-Pakistan Agreement 1963 ("China-Pakistan Agreement") whereby Gen. Ayub Khan of Pakistan handed over parts of Pakistan-occupied Kashmir to China. The agreement purportedly establishes the formal boundary line between China's Xinjiang region and PoK by delineating the boundary alignment along mountain ridges and rivers. The said concession of territory to China was illegal from the start as the Shaksgam valley was rightfully an Indian territory that was under the illegal occupation of Pakistan. As such, as per the legal maxim nemo dat quod non habet (No one gives what he does), Pakistan could not have gifted what was not rightfully its territory in the first place. [...] The Shaksgam Valley dispute is a notable example of China's repeated attempts to unilaterally usurp the territorial sovereignty of other nations, reflecting its broader strategy to monitor and manage India's regional activities. As evidenced in Bhutan and Nepal, China aims to surveil India in addition to containing India within the subcontinent, thereby expanding its maritime presence. India's keen awareness of the recent construction activities in this contested area underscores its vigilance. India has firmly asserted its right to protect its territorial boundaries and undertake any measure to safeguard its sovereign integrity. This enduring dispute highlights the persistent tensions and complexities inherent in Sino-Indian relations and throws light on the Chinese policy of disrespect towards sovereign boundaries weather on land or at sea.
