China-America trade friction originates from American economic policy adjustment, opinion emotion orientation and industrial technological strategy consideration. In view of China, its emotional influence is bigger than practical impact. Although the trade war will produce short-term shock on China’s economic growth, its practical impact and risk are far lower than ten years ago under the background of China’s economic transition from export-oriented to domestic demand driving. Furthermore, this event practically provides the opportunity for China to further deepen the reform and opening-up. Therefore, China’s rational responding policy is that “you wage your trade war while we wage our trade war”, that by preventing the risk, promoting the reform and boosting the opening-up, China will realize the self risk clearing and structure adjusting of Chinese economy, speed up to carry out“the Belt and Road” proposal under the condition of keeping the basic stability of foreign hard currencies, and lay the basis for a new round of China’s economic growth by deepening the reform, boosting stability and higher quality development, by all-round boosting higher level development, and finally by changing the challenge into the opportunity.
