Themed "Innovation for a Green New Era" this year, the three-day event brought officials and experts from home and abroad to share thoughts and give policy advice to the Chinese government on how to promote low carbon and green development.

Eight forums and one roundtable also have taken place, focusing on topics that include biodiversity conservation, climate change, green Belt and Road Initiative, green consumption, and marine governance.

"The meeting is a great opportunity for people to exchange information to better understand each other and for us as foreigners to come with a better understanding of China," said Arthur Hanson, the council's international chief advisor.
