Why quad alliance is a turning point for India-china ties

The Quad summit hosted by US President Joe Biden on March 12 caps an extraordinary year that saw a fundamental shift in India’s response to China’s border aggressions, precipitating a showdown that has been in the making, but one which many had felt might be averted by balancing border discord with economic interests.
India’s tightrope walk ended soon after Chinese troops occupied positions along the Line of Actual Control in east Ladakh in May last year, clearly violating India’s claim lines. The strength of the mobilisation and ingress in the Pangong lake area signalled an intent to bend the LAC permanently to suit China’s supreme leader Xi Jinping’s political and strategic objectives.
