The most populous country in Asia is China, with a population of over 1.4 billion people. This makes China the most populous country not only in Asia but also in the world.
India, the second most populous country in Asia, has a population of over 1.3 billion people. While India is very populous, it is still smaller than China's population. Russia, although a large country, is not in Asia in its entirety. The part of Russia that is in Asia has a much smaller population compared to China and India. The Kingdom of Saudi Arabia, located in the Middle East, has a population of around 34 million, which is significantly smaller than the populations of China and India.
