Peace or Turbulence, which is the historical norm?

At a time when a growing number of regional conflicts have led to further international tensions, the recent phone call between top leaders of China and the U.S. has drawn wide attention to whether the two global powers can inject some stability into the world. Are decades of globalization and relative world peace coming to an end? Are we moving toward a second Cold War and seeing a replay of the 1930s? What is the root cause of global instability? Is it more of economical or political nature? Today on our program we have Professor Da Wei to share his views on the trend of international relations. Professor Da Wei is the director of CISS, Tsinghua University, and we caught up with him on the sidelines of the 6th Forum on Security and Strategy.
