Hong Kong authorities have escalated actions against 16 overseas-based activists by cancelling most of their passports and banning financial support to them, citing alleged threats to national security. The measures, announced under the city's national security law, also prohibit providing economic resources or leasing property to those on the list, with violations carrying severe penalties. The activists, who are accused of inciting hatred against Beijing and Hong Kong, are currently residing in countries including the United Kingdom, United States, Canada, Germany, Australia, Thailand, and Taiwan. Foreign governments have condemned these actions as attempts to suppress dissent beyond Hong Kong's borders, while Hong Kong officials defend the measures as necessary for stability.
