An opening ceremony was held on Tuesday for Hong Kong's new National Security Exhibition Gallery, with Chief Executive John Lee calling for a wide range of visitors to the attraction.

The gallery, at the Hong Kong Museum of History, will open to the public on Wednesday.

Lee said he hopes various groups of people will visit, including groups from primary and secondary schools and youth organisations.

He emphasised the crucial role of such visits in effectively promoting national security education.

The CE stressed that safeguarding national security is a responsibility of the SAR government. He reiterated the government's commitment to accurately and fully upholding the One Country, Two Systems principle, while safeguarding national sovereignty, security and development.

"Safeguarding national security is always a work in progress. There is no completion. Given the ever-changing international situation, it is necessary to maintain a sense of crisis," he said.

Speaking at the same event, Zheng Yanxiong, director of Beijing's liaison office, described the gallery as a place to help citizens better understand national security.

"The opening of the National Security Exhibition Gallery will further consolidate the consensus that security brings prosperity, and cultivate the grounds for safeguarding national security," he said.
