The year 2019 marks the 70th anniversary of the founding of the People's Republic of China. The achievements of China's development over the past 70 years show that we must remain committed to the path of peaceful development and pursue a mutually beneficial strategy of opening up. Since the 18th National Congress of the Communist Party of China, China has made positive contributions to promoting global openness, connectivity, mutual benefit and common development, and has played an important role for the world peace and stability. At present, in order to cope with the uncertainty in globalization, we should positively explore ways to construct an open world economy, elaborate measures to build consensus among international community, and provide intellectual support for building of the community with a shared future for mankind.
