Indonesians don't mind saying "too many people", as most of their population of 270+ million lives on the island of Java. However they have other very large islands (Sumatra, and part of Borneo) that could be settled, so it's not an insurmountable problem. China's and India's large populations are their Achilles heels - they need vast quantities of food and water, yet China imports 50% of some food items, and India relies on Himalayan headwaters that China is diverting.
