While climate foreign aid is an emerging field of China's South-South cooperation,it is an impor-tant way for China to participate in global climate governance.The institutional arrangements of climate for-eign aid are rooted in the socialism with Chinese characteristics,forming a"three-dimensional structure"of the organizational,guiding and regulatory institution of climate foreign aid.Currently,China's climate foreign aid is faced with new situations such as the escalation of the political and economic competitions a-mong the major powers,the increasing downward pressure on the global economy and the transformation of global climate governance.It is necessary to contribute to the function of climate diplomacy,ensure the sup-ply of climate resources,and respond to global climate threats through the institutions of climate foreign aid.At present,there are still shortcomings and deficiencies in the institutions of climate foreign aid,and it is necessary to optimize the organizational institutions,improve the guiding institutions,and promote the regu-latory institutions.This theoretical analysis and optimization plan could provide institutional theoretical ap-proaches or optimization options for China's foreign aid,and also provide institutional experience for the improvement of China's foreign aid.
