Zhang Yansheng, former secretary-general of the Academic Committee of the National Development and Reform Commission, stated that in order to improve the high-level opening-up system and mechanisms, it is necessary to enhance strategic mutual trust. "Seeing is believing, turning enemies into friends," he said. China should grant more countries having close economic and trade relations with China visa-free access for business, making it easier for the world to come to China and for Chinese people to go to the world.
