China，together with New Zealand，was invited by the UN Secretary General to co-lead the action area of Nature-based solution under the 2019 Climate Action Summit. Nature-based solution is an integration and enhancement of various climate actions. Recognizing the value of NBS and enhancing the implementation of NBS could significantly contribute to global climate action and ambition. As the co-lead of NBS track，China has been provided precious opportunity to promote global eco-civilization and to show the leadership in global environment and climate governance，but meanwhile China also faces with challenges of defending state interests，coordinating domestic institutions，as well as networking and publicity. Thus，it is important for China to create a positive and facilitating momentum under the NBS agenda and to keep NBS as an organic whole. It is also needed to engage various stakeholders，and to ensure a focus on the political signal of recognizing and enhancing NBS with follow-up mid-and long-term implementation plans，so that to deliver a comprehensive，balanced，and ambitious outcome，which brings out together China’s concepts and demonstrates China’s willingness of taking due responsibilities and leadership.
