Leaders of diamond trade are slated to meet for a three-day conference here on Tuesday to discuss implementation of Kimberley Process Certification Scheme (KPCS). This certification scheme regulates trade in rough diamonds. India is presiding over the body for KPCS for the year 2008, which came as a natural consequence of it being the vice chair of the body for the year 2007. In November 2006, during the plenary of KPCS in Botswana, India was unanimously selected to be the vice chair of the body for 2007. KPCS is a joint inter-governmental, industry and civil society initiative to stem the flow of conflict diamonds ? rough diamonds used by rebel movements to finance wars against legitimate governments.
