To play a leading role in environmental management in Northeast Asia, the Environment Ministers of the three countries, China, Japan and Korea, have been holding the Tripartite Environment Ministers Meeting (TEMM) every year since 1999, aiming to contribute to improve the environment on a global scale. The TEMM holds its ministerial meeting once a year in rotation among the three countries to promote dialogues and publish a joint communiqué. The TEMM sets eight priority areas and each of its cooperative projects is implemented according to the agreements at the ministerial meetings.
Launched as part of the first priority area “Air quality improvement”, the joint research on DSS has one of the longest history in the TEMM cooperation. Two working groups on DSS (WG I and WG II) consisted of selected researchers from China, Japan and Korea have been exchanging research outcomes on DSS every year since 2008.
