One of the highlights of the Congresses is the award of the Morningside Medals of Mathematics and the Chern Prize. Awardees are selected by a panel of international renowned mathematicians with the aim to encourage outstanding mathematicians of Chinese descent in their pursuit of mathematical truth.

The Fourth ICCM (ICCM2007) will be held in Center of Mathematical Sciences,Zhejiang University in December 2007. There will be 14 plenary lectures and 40 special sessions on mathematical topics. Besides the invited lectures, there will also be contributed and poster sessions.
