Abstract: Where there are countries, there will be borders. How to enhance the control capabilities of land border channels is a universal challenge that the vast majority of countries in the world will face. At present, although China’s land border channels have played significant role in serving as “gateway” and “checkpoint”, there have been some drawbacks in terms of public safety concepts, institutional guarantees, organizational structures, differentiated guarantee capabilities, social participation, resource investment, construction of smart border channels, and cooperation with neighboring countries in public security that all need to be further strengthened, against the background that the world today is undergoing profound changes unseen in a century. Therefore, it is necessary to optimize the path to enhance the public security capacity from multiple perspectives and levels, so that the linking role of the “bridge” and the defensive role of the “wall” can be effectively exerted, thus ensuring border stability and national security.

Key words: land border passage, public security, optimize the path
