British authorities convict two men of spying activities linked to China targeting dissidents living in the UK. The defendants are Peter Wai, a UK Border Force officer, and Bill Yuen, a retired Hong Kong police officer. Multiple reports say they were involved in surveillance of Chinese dissidents based in Britain and of senior UK Members of Parliament who support those dissidents. The coverage also describes the alleged work as part of broader “shadow policing” or transnational repression efforts associated with the Chinese state. One outlet reports that MI5 issues a warning characterising the activity as “transnational repression,” tying it to efforts by China to reach beyond its jurisdictions and monitor perceived opponents abroad. The reports frame the alleged operations as extending outside Hong Kong and into the UK, where the men are said to have carried out or supported surveillance. Together, the sources describe a conviction for espionage and surveillance activities connected to China, with MI5 publicly warning about the wider threat of cross-border repression.
