The article seeks to investigate how alliance formation and balance of power patterns will unfold in South Asia in the wake of an intensifying geopolitical rivalry between the United States and China. Both the United States (US) and China form an intrinsic part of South Asia’s geopolitical security architecture through their embeddedness with both Pakistan and India. Historically, Pakistan relied on both American and Chinese security assistance in balancing against India while India relied more on the former Soviet Union and the US in its balancing game against Pakistan. As current geopolitical dynamics unfold with the US pivot to Asia, the rivalry and competition between the US and China is intensifying, bringing with it a similar dynamic in South Asia as Pakistan moves closer to China and India consolidates its alliance with the US. The paper concludes that, keeping current global security dynamics into perspective, the relational dynamics between Pakistan and India stands to unfold in a competitive and adversarial balance of power scenario.
