Distinguished Guests and Colleagues：

Welcome to PasteChina 2026!

It is our great honor to cordially invite you to the Chinese Academy of Engineering International Symposium on Engineering Science and Technology — International Cooperation on Green Minerals & the 6th International Symposium on Paste Backfill Mining in China (PasteChina 2026). The event is scheduled to take place in Kunming, Yunnan Province, on October 26-29, 2026. As international cooperation under the “Belt and Road” Initiative continues to deepen, the green transition and sustainable development of mineral resources have become shared priorities worldwide. Paste backfill mining technology, with its remarkable advantages in "safety, environmental protection, cost-effectiveness, and efficiency," has become a trending technology in green mine construction and an essential means for the mining sector to achieve Carbon Neutrality. Since its launch by the University of Science and Technology Beijing in 2013, PasteChina has been successfully held five times and has grown into a professional, forward-looking, and open platform for high-level academic exchange in the global mining field. The theme of this year’s symposium is "Green, Intelligent, Innovative, and Cooperation." We warmly welcome colleagues and friends from around the world to Kunming, the beautiful “Spring City,” to share insights, strengthen cooperation, and explore the future of green mining!
