Because it does not have the "high fructose corn syrup" but regular sugar.

All sodas in India (even Pepsi, Coke sold in India) use sugar instead of corn syrup so it doesn't leave sticky sweetness in your mouth.

Try "Pepsi Cola" in US that still contains sugar.

Cuban relations and bad foreign policy in the 1970s forced the switchover to corn syrup. Despite the wishes of Coke[1].
