In recent times, there have been many exchanges between China and the United States, and bilateral relations have shown a trend of stabilizing and stabilizing, bringing rare good news to a turbulent and intertwined world. To make the expectations for stability and development of Sino US relations a reality, China and the United States need to move towards each other. The action roadmap is also very clear, which is to return to Bali and lead to San Francisco, truly implement the consensus of the China US dollar Bali summit, expand the positive agenda of bilateral relations, reduce negative agendas, and create conditions, eliminate interference, accumulate results, and create an atmosphere for the San Francisco meeting. Undoubtedly, the journey back to Bali and to San Francisco will not be smooth sailing and cannot rely on autonomous driving. The experience and lessons from the ups and downs of China US relations in recent years indicate that it is particularly important to grasp the "three dimensions" well.
