参考答案：In recent years, China’s economy has maintained rapid development, injecting vigor into global economic growth. Facts have confirmed the prediction made by China before its WTO accession: China’s development cannot be sustained without the world, and world development needs China. In the coming 20 years, China is bound to make historic contributions to global economic development and to the common progress of mankind, while building a well-off society in an all-round way. To achieve this, China will continue to expand foreign trade, energetically implement its west development strategy, further improve its investment environment, and provide overseas investors with greater business opportunities. Meanwhile, it will guide and support competitive enterprises to invest overseas and carry out diverse forms of economic and technological cooperation on the basis of equality and mutual benefit. China will further intensify bilateral, multilateral and regional economic cooperation, so as to achieve common development in all countries and regions in the world.
