Beijing’s surprise choice to spearhead the national security law in Hong Kong
- Guangdong-born Cantonese speaker Zheng Yanxiong will be the public face of the agency overseeing implementation of the law in the city
- The hardliner has a background in propaganda that some analysts say could serve him well in his new role

The day-to-day operations of the office will be handled by Zheng’s two deputies, Li Jiangzhou and Sun Qingye. The former is a veteran public security officer and has worked in the central government’s liaison office in Hong Kong since 2016. Sun is a senior official from China’s intelligence agency, according to government sources.
The detailed office structure is not expected to be made public. Most officials in the office are expected to keep a low profile, according to official sources.
The national security office is the fourth Beijing outpost to be established in Hong Kong. It has the power to supervise how the Hong Kong government implements the national security law as well as gather intelligence and handle cases directly at its discretion. It is also charged with working with other central and local government agencies to tighten control over foreign non-government organisations and media in Hong Kong.
