It is our great pleasure to invite you to attend the international conference on “Resources, environment and regional sustainable development in Northeast Asia”, which will be held in Changchun, Jilin province, China, from June 10th to 15th 2014, under the sponsorship of the Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences. The impact of economic globalization and global change on human sustainable development has been more and more perceptible since the 21st century. Northeast Asia is one of the important regions affecting the sustainable development of the world because of richer natural resources, better environment condition and larger potential for economic development. Due to historical and geopolitical reasons, the cooperation among Northeast Asia region is progressing at a quite slow speed. Problems such as gaps of regional economy, environment and social development closely related to each other within Northeast Asia. It is of vital importance to strengthen co-operations among countries and take effective measures to solve these problems. This conference will attract talents of relevant fields to discuss issues on resources, environment and sustainable development in Northeast Asia region, try to work out adaptable measures to these problems, and promote the cooperation, prosperity and regional sustainable development in Northeast Asia. We hope this conference will provide a great opportunity for researchers in the international community to exchange ideas on resources, environment, and sustainable development in Northeast Asia. We look forward to seeing you in Changchun, Jilin province, China.
