It’s been another busy week with significant developments on the national security news front.

Publishing tycoon Jimmy Lai made international headlines last Friday when he was jailed for 14 months in back-to-back sentencing. While still in custody pending trial on national security charges, he was given two more prison terms for his role in two illegal protests during Hong Kong’s anti-government unrest in 2019, while four former opposition lawmakers who joined one or both rallies were also jailed.

While Western governments and other critics condemned the sentencesas “repression” and silencing of peaceful dissent, Hong Kong authorities hit back, saying they were “appalled” by demands for the release of defendants who had either admitted to breaking the law or been convicted after trial in court.

Just a day before that, Hong Kong officially celebrated National Security Education Day. Citywide events were held to mark the occasion, ranging from Chinese military-style marches and anti-terrorism drills to school promotional activities for children and weapons displays for pupils, while top officials made speeches urging unity to maintain stability and resist foreign interference.
