The Prime Minister, Dr Manmohan Singh, has proposed creation of rural business hubs on the lines of the Chinese model and a revamp of different rural development programmes to make agriculture an engine of growth. "We must examine our rural development programmes afresh. Concerns that we have not been able to unlock varying resource potential of different regions and use funds optimally to make Panchayat Raj Institutions effective can perhaps be addressed by such a policy shift," Dr Singh told a Chief Ministers' conference on Panchayat Raj in the Capital.
