Xia Baolong, Beijing’s top man on Hong Kong affairs, and other leading officials are addressing the city as part of the opening ceremony of an event to mark National Security Education Day on the 10th anniversary of the unveiling of a holistic approach to protecting the country’s safety.

Chief Executive John Lee Ka-chiu is among those speaking at the ceremony, being held at the Convention and Exhibition Centre in Wan Chai on Monday, as well as Zheng Yanxiong, the director of the central government’s liaison office in the city.

It is also the first National Security Education Day after the Safeguarding National Security Ordinance – legislation mandated under Article 23 of the Basic Law, the city’s mini-constitution – came into force last month.

The day was first launched to raise public awareness of national security and create a positive atmosphere around its safeguarding.

It was also designed to boost the city’s ability to avoid national security risks.
