I'm not sure what withdrawl they mean. The US withdrew from Afghanistan, but that is clearly Central Asia and not South Asia (unless it's defined differently in India?).
The US has withdrawn from other regions, especially the Mideast, in order to focus on China. But the US very much considers the Indian Ocean as part of the competition with China (usually using the term 'Indo-Pacific'; even the military command there is INDOPACOM); I'd be surprised if it ceded South Asia to China.
India considers Afghanistan part of or ought to be part of India. It even has a map for it.

Out of curiosity, do you know anything about the publication, Modern Diplomacy? It has a lot of interesting coverage that isn't generally available elsewhere, but I have no idea how much and in what ways to trust it.
We too quickly forget our history if we don't expect that or think popularity confers rational or moral legitimacy: Mao, Lenin/Stalin, Hitler, not to mention Pol Pot, Suharto, Pinochet, etc etc. were very popular.
