He remains a member of the CPPCC and the party, a source told the South China Morning Post.
Zhang, 60, was a minister-level official and is below the usual retirement age of 65.
He began working at the Hong Kong and Macau Affairs Office (HKMAO) in 1989 after graduating from Renmin University of China’s law school, serving as the agency’s deputy director from 2004 to 2012.
He was then promoted to director of Beijing’s liaison office in Hong Kong, and became director of the HKMAO in 2017.
In 2022, Zhang was appointed to the deputy role in the nation’s top advisory body.
“[I] respect and trust the central government’s personnel arrangements,” Starry Lee Wai-king, the city’s sole representative on the National People’s Congress Standing Committee, told the Post.
