Little = no?

Context:

System change, the theme of the World Cancer Congress in Shenzhen, China, Aug 18—21, was a central message in the opening address by the Chinese Minister of Health, Chen Zhu, as he described current health-care system reforms in China. At the Congress many international health policy makers and physicians led discussions on frameworks and actions for system change, but there was little participation from local Chinese doctors.

To understand why there were so few Chinese delegates in the plenary sessions on system change compared with sessions on patients' care, one must first understand that for many Chinese doctors personal safety is of greater concern. Chinese doctors are often victims of terrible violence.
