Zhou Yongjun incident

The Zhou Yongjun incident was a political controversy which involved the rendition of Zhou Yongjun (周勇军), a former student activist during the Tiananmen Square protests of 1989, by the Hong Kong authorities to the People's Republic of China. Zhou attempted to enter Hong Kong from the United States via Macau using a forged Malaysian passport. Zhou's supporters alleged the renditioning to be illegal, and his lawyer, Democratic Party chairman Albert Ho, described Zhou's case as "posing the biggest challenge to the one country, two systems principle laid down in the Basic Law." The Government of Hong Kong refused to comment on individual cases, and the People's Republic of China said Zhou was detained on several charges, including one of financial fraud.
