Chinese State Councilor and Foreign Minister Wang Yi delivered a speech to the United Nations General Assembly in New York on Saturday. Wang Yi said this is an era full of challenges. The world has entered a new period of turbulence and change. This is also a time of hope. World multi-polarization, economic globalization, social informatization, and cultural diversification are developing in depth, and countries are increasingly connected and interdependent. The theme of the times for peace and development has not changed, and people of all countries have a stronger desire for progress and cooperation.
