The three principles of commercial bank business development refer to

The three principles of commercial bank business development refer to "know your customers", "understand your business" and "due diligence". Banks generally implement the three principles of business development by improving internal control systems and business process design, strengthening departmental division of labor assistance, and strengthening post-loan management, and are more prudent and strict in reviewing the authenticity and compliance of business.

In May 2013, the State Administration of Foreign Exchange introduced the "know your customer" principle for the first time in the "Notice on Relevant Issues Concerning Strengthening the Management of Foreign Exchange Capital Inflows", emphasizing banks' screening of fictitious trade backgrounds and other behaviors. Subsequently, the State Administration of Foreign Exchange required banks to effectively implement the "Three Principles of Business Development" when handling business. Banks have gradually become my country's main line of defense against systemic financial risks.
