Chinese Premier Li Keqiang on Tuesday called for constant improvement of rural financial services in an effort to bring benefits to farmers.

Li made the remarks in a written instruction to a national conference on promoting rural financing service on Tuesday.

"Boosting financial services for farmers, agriculture and rural areas has great significance for ensuring food security, building modern agriculture, raising farmers' incomes and narrowing the urban-rural gap," Li said.

The country should deepen rural financial reform, nurture rural financial market, increase agriculture-related lending and intensify policy supports, the premier said.

He also urged financial institutions to strictly implement the policy of differentiated reserve requirement ratios and improve mechanisms for financial supervision and risk management.

The State Council, the country's Cabinet, on Tuesday unveiled a document on improving financial service for the agriculture sector, rural areas and farmers.

The central bank also announced on Tuesday that it will cut the reserve requirement ratio for county-level rural commercial banks by 2 percentage points and that for rural credit cooperative unions by 0.5 percentage point starting from Friday.
