Finance Minister Mr Pranab Mukherjee today said, the Centre is taking all necessary steps to check price rise of essential commodities. He said measures, both on supply and demand side, are being taken and imports of essential food items on short supply with zero duty are being allowed to improve the situation. Mr Mukherjee, however, said India can't insulate itself from the price rise effect as many global factors like hike in crude oil prices, especially those of diesel are affecting it. Speaking to newsmen at Bhubaneswar, Mr Mukherjee expressed deep concern over the price rise of essential commodities. He said letters have been written to all the chief ministers to act according to the essential commodities act and prevent hoarding of essential commodities. Mr. Mukherjee said, the poor people are being given food commodities on subsidised rates.
