Macau authorities arrested former pro-democracy lawmaker Au Kam-san on July 31, 2025, marking the first use of the city’s national security law since its enactment in 2009 and amendment in 2023. Police accused Au of colluding with foreign forces and anti-China groups, actions alleged to endanger China's national security. His wife was also summoned by prosecutors. The arrest drew condemnation from the European Union, which criticized Macau for lacking pluralism. Separately, in Hong Kong, a man was arrested for threatening media outlets to publish a seditious report promoting a fundraising website for wanted activists. Additionally, Hong Kong authorities canceled passports and banned financial support for 16 overseas activists linked to a subversive organization called the "Hong Kong Parliament," citing national security concerns. The Secretary for Security in Hong Kong exercised powers under the Safeguarding National Security Ordinance to specify these individuals as suspects of offenses endangering national security.
