A high-level opening-up of the financial sector is an important factor and key link for the high-quality development of an open market economy with Chinese characteristics, and it is an inevitable requirement and proper meaning of expanding openness to the outside world in the new era. To improve the quality and level of financial openness in an all-round and multi-level manner, it is necessary to adhere to the strategic orientation towards serving the new development paradigm, and to build a "domestic-international" dual circulation link and bridge through the flow and cooperation of financial resources and elements; to comply with the laws of the economy, and to serve the development of the real economy through financial openness to realize a greater scope of resource allocation and provide strong support for the real economy; to strengthen risk awareness and improve the systematic and comprehensive financial regulation system, and to realize the efficient operation and quality improvement of financial regulation.
