China is making all-out efforts to encourage private investment in more heavily statecontrolled and monopolized sectors amid concerns that its economy might slow further in the coming months.

Since China's transport, railway and health ministries issued guidelines in April to permit private capital to enter those sectors, the banking sector and state-owned enterprises have joined the drive.

The move came in line with other recent measures announced by the Central Government to open state-controlled and monopolized sectors wider to private investment, in a bid to stimulate tepid economic growth.

Detailed rules concerning private investment in more monopolized industries, such as electricity, oil and natural gas are currently being drafted, said an official with the National Development and Reform Commission.
