The pull out of US from the Paris Agreement is a symbol event of“deglobalization”trend dominated by US and UK，also a major challenge to global governance structure. To maintain a beneficial international environment to peaceful growth，it is crucial for China as a guard to promote current globalization process and also seek solutions to resolve many challenges which we are facing. Global climate change is not only a global environment issue，but also a racecourse between“deglobalization”and“reglobalizaiton”，representing the internal necessity for China's goal to become a great modern socialist country. China should defend the principle of equity and fairness，participate and lead the institutional establishment of global climate governance in a deeper manner，with a view to promote win-win cooperation and joint development among countries. The climate change could be an important field and successful example of enhancing national image and“soft power”through expansion of international influence and discourse power.
