Abstract: Crossborder data flow is a fundamental part of digital trade, and it is also a key issue in the international data governance game. At present, China has preliminarily formed a system of rules and regulations for crossborder data flow, but there are still prominent problems such as difficulties in crossborder risk screening, slightly rough rules and systems, difficulties in the dominance of international rules, and weak crossborder regulatory means. To seriously  solve the problem of crossborder data flow, it is urgent to better coordinate development, security and openness to build a crossborder data governance system. The policy system clarifies basic propositions, improves the legal system, refines institutional rules, consolidates technology platforms and expands practice carriers, in order to align with highstandard international economic and trade rules, and gradually form a plan for crossborder data flow with Chinese characteristics.
