Data security governance rules are essential for cross-border data flow. Based on the analysis of cross-border data flow security governance rules of typical countries and bilateral and multinational treaties, China's cross-border data flow security governance rules are studied and relevant suggestions are provided. Firstly, we should refine relevant regulations and improve the data classification supervision system; at the same time, we should improve the blocking law in the data field to avoid the long arm jurisdiction of other countries. Secondly, it is necessary to actively participate in the formulation of international cross-border rules for data, embed data security clauses into international economic and trade rules, and further promote the achievement of global data security flow rules.
