Following President Xi’s recent visit to the U.S., Xi’s concept of “a new model of great power relations” seems to be back on the China-U.S. agenda. Originally pushed by Xi and now being reconsidered by Obama, this concept suggests a major turning point for both countries.

New agreements on collaboration in such areas as agriculture, grain production, civil aviation, high-speed railways, law enforcement, and military-to-military relations will further deepen interdependence. Xi’s visit has increased mutual confidence, reduced mutual suspicion, with achievements that made it a milestone in bilateral relations.

The Chinese president’s visit is the starting point for both sides to promote mutual trust, concrete cooperation and communication, which will brighten prospects for the bilateral relationship. The informal style of talks both leaders favor produce results that should ease lingering suspicions by hardliners in both countries.

China and the United States have a deep stake in each other's success, just as the world has a deep stake in a strong and resilient China-US relationship. The Xi-Obama summits have been far more than “power strolls” for the cameras, and we are all better off because of them.

It may be too early to tell, but one would not risk ridicule by claiming that the just-concluded U.S.-China summit has accomplished its most important, albeit intangible, objective: temporarily arresting the downward spiral in the ties between Washington and Beijing.

The Xi-Obama meetings have demonstrated that China and the US can be frank and open with each other when addressing difficult issues. The result could be a new order in a multipolar world that better accommodates the needs and desires of the entire globe.

The 2015 Obama-Xi Summit must be judged a success. Although areas of disagreement are real and run deep, and not easily resolved progress was made, trust was built, and the two great powers on the planet have stabilized their relations. The question is: How long will it last?

On September 22, 2015, Chinese President Xi Jinping began a state visit to the U.S. Mr. Xi came at a critical moment, especially as recently there have been signs of emerging strategic rivalry in U.S.-China relations.

President Xi's impending visit to the U.S. brings to the light the current state of the Sino-U.S. relationship in all its uncertainty. Strong communication between President Obama and President Xi will be key for cooperation.

As the United States enters a presidential election campaign and prepares for the first state visit of a new Chinese leader, the U.S.-China relationship is at an important inflection point.
