A businesswoman who renounced her Chinese nationality has applied to relinquish her membership of the political advisory body of a Beijing district.
Zhang Lan, founder and chairwoman of the Beijing-based restaurant group South Beauty, has submitted a written application to give up her membership of the Beijing Chaoyang District Committee of the Chinese People`s Political Consultative Conference (CPPCC), Zheng Huang, the committee`s vice chairman told Xinhua on Wednesday...
China does not recognize dual or multiple citizenship. Chinese law stipulates that once a Chinese takes foreign citizenship, he or she loses Chinese nationality. It is unknown what nationality Zhang is.
