In an open letter from Executive Directors of Greenpeace India and US, hours before Modi's speech at the United Nations today, the NGO said these actions serve as a "distraction" and and raise "serious questions" about government's commitment to democracy and environmental issues.
The letter also urged Modi to ask President Barack Obama to "reconsider" US administration's recent actions which "significantly undermine" the fight against climate change.
"The actions of some officials in the MHA and the resultant shrinking of the space for constructive dialogue have served to tarnish India's international standing as a country that respects free speech and democracy.
"At a time when we need to focus instead on the imperatives of the environmental issues facing us all, these actions serve merely as a distraction and raise serious questions about your government's commitment to democracy and to addressing environmental issues," the letter, written by Greenpeace India's Interim Executive Director Vinuta Gopal and Greenpeace US's Executive Director Annie Leonard, said.
The NGO alleged that over the last year, the Home Ministry had frozen Greenpeace India's bank accounts, prevented its staff (including Indian citizens) from entering and leaving the country and cancelled the group's license to receive donations from abroad.
"On the very eve of the Prime Minister's address to the United Nations, the organisation's primary bank account was frozen once again denying Greenpeace access to donations received directly from its Indian supporters," it alleged.
