The year 2016 witnesses the achievement of a milestone in the development of the national security legal system of China. The adoption of the Anti-Spy Law，the National Security Law and the Anti-Terrorism Law，three pillars in China's national security legal system，marks the establishment of a basic legal framework for national security in China. However，empirical research on judicial cases shows that the three laws are rarely quoted in practice，which should be taken seriously. In 2016，a spate of national and local laws and regulations related to national security are passed or amended. The analysis of these laws and regulations shows that China has made breakthroughs in the important legislative areas of national security and has enriched the legal system under the framework of the overall national security outlook. But there is still room for improvement in terms of the quality of legislation and the balance between national security and civil rights. The law enforcement and justice systems have failed to keep up with the pace at which laws are passed. The future focus of China's national security legal system should be shifted to effective law enforcement and timely revision and improvement of the legal system. Local legislative bodies may be encouraged to accumulate legislative experience through experimental legislation.
