官翻：In 2018, we look forward to a world of greater openness and less isolation. The green shoots in the new round of global growth must be nurtured by all countries. What China has learnt in its 40 years of reform and opening up is that prosperity only comes to those who embrace the world with open arms. China will remain committed to opening up as a fundamental policy and a mutually beneficial strategy. We will stay actively engaged in reforming and developing the global governance system to make economic globalization more open, inclusive and balanced so that its benefits can be shared by all. We will work on the Belt and Road Initiative by implementing deliverables of the first Forum and starting preparations for the second one. This way, we can break new ground in opening up. We will host a number of events like the annual conference of the Boao Forum for Asia, the Summit of the Shanghai Cooperation Organization, the Summit of the Forum on China-Africa Cooperation, and the China International Import Expo to add momentum to the trend of openness and development.
