Existing customs issues can be resolved by strengthening communication and cooperation and formulating clear rules and treaties. Countries can timely adjust international trade rules through multilateral trade negotiations, and cooperate with each other to resist unfair customs measures. In addition, establishing a unified customs supervision system and a transparent tariff policy will help reduce trade frictions. At the same time, strengthening international cooperation to combat illegal trade and trade speculation is essential to maintaining international trade order and fair competition. Through the above measures, existing customs issues can be effectively resolved and the healthy development of global trade can be promoted.
