Some time before World War II approached, China and Russia wound up on the same side. For some reason, Russia stalked China frequently and was also often partnered with him. Russia’s “special interest” in China is one of the reasons for his extreme paranoia.
China’s female version is often nicknamed “Nene” or “Wang Chun-Yan”. Russia’s female version, on the other hand, has several nicknames including Kolko, Lucy, Roshiko, Anya Braginskaya, Ivanna, Inna, and Irina.
