China–Manchuria relations,also refered to as Sino–Manchurian relations, refers to the bilateral relationship between the Republic of China and the Manchu Republic. Relations between the two countries are complex ranging from stable to open hostility throughout the course of the history of the relations between the two countries, though historically both countries have been hostile towards one another. Manchuria became functionally independent during the Warlord Era that followed the 1911 Xinhai Revolution, and in 1917 it proclaimed its full independence with Japanese backing, which China refused to recognize.
After the Manchu People's Republic was formally established in 1948 and the People's Republic of China in 1949, both countries had established proper relations. Positive relations were done by Mao Zedong who supported ideological solidarity between the two communist states, however after Maos' death the Chinese government took a more aggressive stance under Zhou Zhiyong leading to the 1976 October Crisis.
By the year 2000, both Manchuria and China sought a fresh start and established friendly relations in a period which is refered to as the "Golden age of Sino-Manchurian relations" which lasted from 2001 until 2014 when the Rehe Province Crisis broke out and ended with the province being annexed by China and absorbed into the Republic of China. The move resulted in a snap presidential election in 2014 and a nationalist government was elected in Manchuria which remains in power as of 2020. Hostility remains between the two countries with regular skirmishes between border guards along the new unrecognized China-Manchuria border. The League of Nations and most countries recognized the Rehe Province as part of Manchuria, under a Chinese occupation.
Since January 22, a crisis has occured on the border as a result of a Chinese military buildup and fears of a potential war.
