The Chinese Federation (中華連邦, Zhōnghuá liánbāng, Chūka renpō) (1912 a.t.b.-2018 a.t.b.) was one of the three dominant superpowers in the world. As it sits immediately to the West of Japan, it receives a fair amount of coverage, particularly in the second season. After joining the United Federation of Nations, it became the United States of China (合衆国中華, Hézhòngguó Zhōnghuá, Gasshūkoku Chūka, "Federal State of China").
