India plans to spend $1 billion to expedite the construction of 12 hydropower stations in the northeastern Himalayan state of Arunachal Pradesh, two government sources said, a move that could raise tensions with China that lays claims to the region.

The federal finance ministry under Nirmala Sitharaman recently approved up to 7.5 billion rupees ($89.85 million) in financial assistance to each hydropower project in the northeastern region, the sources said.

Under the scheme, about 90 billion rupees will likely be allotted for the 12 hydropower projects in Arunachal Pradesh, said the sources, who have direct knowledge of the matter.
