"I will rake up the issue of special state category status for Bihar with the Centre," Kumar told reporters here.
The 'special category' status would help attract private investment and reduce the burden on the state where the government is the predominant engine for development.
"More and more investment is necessary for carrying forward the development of the state," he said.
Kumar said he would also seek an additional grant of Rs 4,000 crore per annum for the state during the regional conference of the Planning Commission to be held in the city on Monday, May 30.
The chief minister said he will also seek a special port for Bihar and would also press for giving 50 per cent share of the electricity being produced by the NTPC plants in the state.
