After seven years of run-ins, China-U.S. Strategic and Economic Dialogue (S&ED) has grown into one of the most solid frameworks for dialogue ever existent between the world's largest developed and developing economies. Besides strategic and economic dialogues, the framework also contains a vice-ministerial security consultation for military and civilian officials from both sides to exchange views on everything from maritime affairs and outer space, cyber and nuclear security, as well as bilateral military exchanges.

However, the 2015 S&ED in Washington, D.C., on June 23 and 24 presented a much more complicated situation for both sides. Owing to their rift on the South China Sea and cybersecurity as well as the ever-shifting state of inter-country relationships, feelings of mutual distrust between China and the United States are growing and their relations may be at a tipping point.

Fruitful outcomes

Outstanding issues aside, China and the United States made efforts to emphasize partnership building and allaying public concerns in both countries, ahead of Chinese President Xi Jinping's scheduled visit to the United States in September.

In the joint opening ceremony of the 2015 S&ED and the Sixth China-U.S. High-Level Consultations on the People-to-People Exchange (CPE), Chinese Vice Premier Liu Yandong read a message from President Xi to U.S. President Barack Obama stating that the priority of China's foreign policy is to build a new type of major-country relationship with the United States based on non-confrontation, non-conflict, cooperation and a win-win principle.

In his speech at the opening ceremony, U.S. Vice President Joe Biden compared the "complicated" relationship between the two countries to a marriage--complete with challenges but shared interests. "We all know, like a good marriage it requires an awful lot of hard, hard work," Biden said. "Let me be crystal clear…We do not fear China's rise, we want to see China rise, to continue to rise in a responsible way that will benefit you most. A rising China can be a significant asset for the region and the world, and selfishly, for the United States."

Chinese Vice Premier Wang Yang maintained that dialogue promotes understanding and benefits both countries. "Some believe that the Thucydides trap between major countries is insurmountable. And some even want China and the United States to confront each other. In any case, decision-makers of both countries must always remember that confrontation is a negative sum game in which both sides will pay heavy prices and the world will suffer too," Wang said.

There is no doubt that progress was made during the S&ED. On the economic track, more than 70 agreements were reached, and on the strategic track, 127 achievements were made in nine fields. The militaries of both countries reiterated their intention to implement a reciprocal notification mechanism for military operations and the Rules of Behavior for Safety of Air and Maritime Encounters, and to reach an agreement on a set of rules for air encounters part before September this year. Both sides also made headway in the fields of energy, climate change and the environment. As a part of their proposed civil space cooperation, the two countries agreed to hold consultations to avoid accidental collision of satellites in orbit.

During the CPE, the signs were likewise promising. The two sides reached a consensus on 119 items in seven fields. With respect to education, China will invite 100 young elite American students to visit China over the coming five years, push forward with a talent-exchange program that will involve 1,000 students from leading universities of both countries and send 10,000 Chinese people to study in the United States annually. All of this takes place in the face of mounting pessimism as regards relations between the two countries.
