Khitai

Khitai, officially known as the Khitan Federation and in complete the Liberal Federate Republic of Khitai, also nicknamed Siberia in popular culture; is a country which encompasses Northern, Northeast and Inner Asia, with small portions of its territories located within Europe. Khitai borders China, Korea and Japan to its southeast; India to its south; Russia to its west and Persia to its southwest, the country also possesses a maritime border with Alaska to the very far east. It currently is the largest country in the world, its territories can fit half of Africa..

Khitai is the third most populated country, with a population of over 600 million. Its national and political capital Xikin exceeds the 9 million in terms of population, but its financial and economic center is Hailinkian.

Khitai derives from a combination of religion, racial identity and ethnic pride, and also legendary tales associated with the country as well as the mass immigration which occurred during climatic changes in the 21st century, essentially from China and Myanmar. If we don't take into account its legendary history, the country has passed from colonized, wild lands to a technological and cultural hyperpower then superpower in a century.
