The Indian government has cancelled a licence which allows Greenpeace India to receive donations from abroad, according to the organisation which campaigns for the environment.
"It is yet another attempt to silence campaigns for a more sustainable future and transparency in public processes," Greenpeace India said in a statement released late on Thursday.
It said cutting access to its foreign funding was "a desperate attempt to get us to cease our work", but added that as the majority of the group's funding came from within India, most of their projects would continue.
The foreign funding licence was cancelled on Thursday, a home ministry official told the BBC.
Earlier this year the government blocked the group’s bank accounts, accusing it of violating tax laws and working against India's economic interest. Two accounts were later unblocked.
