IN response to changes in China’s development level,environment,and conditions,Chinese President Xi Jinping recently called for the country to nurture a new development pattern that takes the domestic market as the mainstay while letting domestic and foreign markets boost each other.This call reflects a strategic choice China has made to reshape its advantages in international cooperation and competition.As the new development pattern underlines domestic and foreign markets reinforcing each other,it will be impossible to achieve without high-standard opening-up,which creates the conditions,provides the driving force,and serves as safeguards for sound development.
