Further national-security legislation followed under Article 23 in March 2024.[6]

1.
Claim: The 1984 Sino-British Joint Declaration set the terms for Hong Kong's return to Chinese sovereignty, establishing a "One Country, Two Systems" framework under which Hong Kong's existing social, economic and legal systems, including its capitalist economy, independent judiciary, and freedoms of press, expression and assembly under the Basic Law, would remain unchanged for fifty years after the handover; the United Kingdom transferred sovereignty over Hong Kong to China on 1 July 1997.

Claim: The 2014 Umbrella Movement was a mass protest movement, named for demonstrators' use of umbrellas against police measures, that arose after Beijing proposed a framework limiting Hong Kong's promised universal suffrage to a pre-screened slate of candidates; demonstrators demanded genuine democratic electoral reform rather than the constrained arrangement offered.

Claim: Demosistō, a political party led largely by former student activists including Joshua Wong and Nathan Law, was founded on 10 April 2016 and advocated a referendum on Hong Kong's sovereignty to be held around 2047, when the "One Country, Two Systems" arrangement is due to expire; the party framed this as "democratic self-determination," distinguishing its position from other, more explicitly pro-independence groups' calls for outright "national self-determination" or independence.

Claim: Large-scale protests in 2019-2020, the largest in Hong Kong's modern history, arose initially over a proposed bill permitting extradition to mainland China; although the bill was withdrawn, demonstrations continued for months amid reports of police conduct that drew international attention, before subsiding amid the COVID-19 pandemic. This bundle does not narrate specific protest incidents or allegations of police conduct in detail.

5.
Claim: On 30 June 2020, the government of China imposed a national security law on Hong Kong by bypassing the territory's own legislature, criminalizing acts it defined broadly as secession, subversion, terrorism, and collusion with foreign forces. Effects reported by 2024 included hundreds of arrests of activists and journalists, the closure of pro-democracy publications such as Apple Daily, the departure of large numbers of journalists from the territory, and the disbanding or inactivity of youth-oriented political parties including Demosistō.

Claim: In March 2024, Hong Kong's legislature enacted its own additional national-security legislation under Article 23 of the Basic Law, broadening definitions of offences such as espionage and "external interference"; this has been described as further extending Beijing's legal control over the territory and creating a chilling effect on international business and professional activity there.
