As independent directors have formed an integral part of the Chinese corporate governance model for more than a decade, it is now timely and important to examine their performance of their monitoring functions. By studying the administrative sanctions imposed on independent directors by the CSRC, this article can offer several important empirical findings.

It also explores the 'independence' of independent directors and examines their responsibilities in light of their reliance on professional third-party reports. The article argues that, similar to their Western counterparts, independent directors in China are facing intrinsic dilemmas in the process of performing their monitoring functions.
