Joshua Wong pleaded guilty on September 2, 2026 to a charge of conspiring to collude with foreign forces under Hong Kong’s national security law, the case heard at the High Court (Admiralty).

Prosecutors said the charge alleges that Wong conspired with exiled activist Nathan Law and others between July 1 and November 23, 2020 to ask foreign countries, institutions or individuals to impose sanctions, blockades or other hostile measures against Hong Kong or China.

Prosecutors cited examples in the case, including that Wong shared an online petition by Nathan Law urging digital-forensics companies to stop cooperating with Hong Kong police; they alleged that one company later announced it would stop selling certain digital-intelligence offerings to customers in Hong Kong and China.

The collusion-with-foreign-forces offence under the national security law can carry a maximum sentence of life imprisonment. Reporting across outlets has cited an ordinary statutory range of about three to ten years unless the offence is deemed 'of a grave nature,' which can allow life terms. Multiple outlets also noted that pleading guilty typically can result in a reduced sentence under Hong Kong sentencing practice for guilty pleas in these cases.

Wong was already imprisoned on an earlier national security conviction — for conspiracy to commit subversion linked to the 2020 unofficial primary — and was serving a sentence of about four years and eight months that had been scheduled to end in early 2027 prior to his re-arrest in June 2025 on the collusion-related allegation.

The plea and sentencing hearing took place at the High Court (Admiralty). Reports describe Wong appearing in court wearing a dark-blue shirt and black-rimmed glasses, gesturing and waving to onlookers, and confirming the factual details read out by the prosecution.

Sentencing was expected after the guilty plea, either later in the same hearing or at a subsequent hearing; the sources collected did not report a final sentence length.

Wong rose to prominence as a student activist in 2012–2014 — including during the 2014 Occupy movement — co-founded the pro-democracy group Demosisto, and was active in the 2019 protests, background frequently cited in coverage of the case.
