Financial security is an important part of national security. In the Central Economic Working Conference，held in 2017，preventing and resolving major risks was listed the first place in three major targets，and the focus was on the prevention and control of financial risks，which set the general tone for China’s financial industry for a long time to come. Since the 18th National Congress of the Communist Party of China，China’s financial reform has been deepened comprehensively，and the ability to hold the bottom lines of no systemic financial risk has been increased. However，there are also problems such as economic structural imbalance，prominent risks in key areas and weak supervision. In order to do financial work well in the new situation，preventing risk must be put in the first place，and with serving the supply-side structural reform as the main line，make efforts around the “Three Virtuous Circles”，and stick to the bottom-line thinking，and do a good job in preventing and controlling risks in key areas，making powerful regulation the norm.
