Crazy levels of disinformation in the replies. For information: Gui Minhai successfully renounced his Chinese citizenship, and became a full Swedish citizen. He was abducted in Thailand, and taken to China, where he was tried under CHINESE LAW as a CHINESE CITIZEN. In China he “voluntarily” renounced his Swedish citizenship in forced confession videos. What this tells you is that the CCP will assert the primacy of Chinese citizenship where it suits them, and often predicated on the ethnic identity of the subject, regardless of their citizenship. The basic rule according to the legislation (as if the letter of the law matters) is that if one of your parents has settled abroad, and you were born elsewhere and had foreign nationality at birth, you are not a Chinese citizen. However, if you are considered of Chinese descent, and the CCP wants to treat you under Chinese law, they will do so on the basis of your ethnic identity. If you really want to get into the weeds, my tweet was about the UK context, based on the 19th Session of the Standing Committee of the 8th National People’s Congress, 1996. See below for excerpt. It’s a racist policy, and simply unbelievable that other countries are content with their citizenship being treated so cheaply.
