In 2021，Shanghai promulgated the implementation measures of the anti-terrorism law，which is the first anti-terrorism legislation practice in megacities of China. For a long time，Shanghai has faced enormous risks and challenges in countering terrorism and maintaining stability，which needs to be dealt with through local legislation. Shanghai has a solid foundation for anti-terrorism legislation；and problem-oriented and demand-oriented legislative work shall insist on prevention as the priority，punishment and prevention as well. The implementation measures are unified with the higher-level law in terms of style and highlight characteristics in content，which are mainly reflected in the more stringent anti-terrorism responsibility system，the more solid anti-terrorism security prevention system，the more powerful anti-terrorism safeguard measures，and the clearer anti-terrorism legal responsibilities.
