Asia offers very diverse travel options. There are ultra modern, largely democratic countries like Japan and the East Asian Tigers (regions and countries) of Singapore, Hong Kong, Taiwan and South Korea which are very prosperous and in which people enjoy very high standards of living. On the other hand, Afghanistan, Laos and East Timor are extremely poor countries where people struggle even to get a few grains of rice each day.
Of course, there are also many countries lying somewhere in the middle, such as the emerging powerhouses of China and India which make wonderful travel destinations in themselves due to their long history, size and diversity. Thailand is a magnet for travelers, with great food, a tropical climate, fascinating culture, and great beaches. On the other extreme, Asia houses Communist North Korea, perhaps the most oppressive regime in the world, which has no travel freedom and constant monitoring by the government.
