The "Belt and Road" Initiative keeps with the trend of the time, and brings China and other countries along the routes ample opportunities of economic, political and cultural exchanges. During its implementation, the spread of Chinese is essential and indispensable. This paper will propose some feasible suggestions by analyzing and examining the opportunities and challenges for the internationalization of Chinese language. The "Belt and Road" Initiative, whose full name is "Silk Road Economic Belt" and "21;Century Maritime Silk Road", covers 65 countries in Asia-Pacific, Eurasia, Middle East, Africa, and South Pacific and serves as the economic corridor that stretches across several continents. Under the "Belt and Road" Initiative, the Chinese language spreads via the economic, political and cultural exchanges between China and other countries across the routes, and guarantees the smooth development and implementation of all policies that involve economy, politics and culture.
