The RCEES has established academic exchanges, cooperation and joint graduate student training initiatives with Germany, USA, Japan, UK, Canada, Sweden, Switzerland, the Netherlands, Australia and other countries. RCEES has cooperated with national universities in offering joint postgraduate programs and carrying out joint research projects. Every year, some young research staff are sent abroad to work or to study for higher degrees. Many researchers go abroad to attend international conferences, or to do collaborative research work.

RCEES has organized many important international conferences on eco-environmental sciences and promoted the cooperation and exchange among foreign and Chinese scientists.

Visiting scholars, foreign students and graduate students are welcomed to work in RCEES, and proper working facilities and personal accommodations will be provided.
