Xi Jinping emphasized that China attaches great importance to the development of satellite navigation systems and actively carries out international cooperation. The Beidou system has become one of the important achievements China has made in the 40 years of reform and opening up. At the end of this year, the Beidou system will be open to the “Belt and Road” countries and regions. In 2020, the service will cover the whole world. Before 2035, a comprehensive, more integrated and smarter integrated space-time system will be built.
