Peace talks held this week in the Netherlands between Indian negotiators and separatists from the northeastern state of Nagaland have failed to yield any result, a rebel leader said on Sunday.
"Nothing concrete materialised in the Amsterdam talks and we are disappointed," Kraibo Chawang, a spokesman for the Isak-Muivah faction of the National Socialist Council of Nagaland (NSCN-IM), told AFP.
The group on Thursday wrapped up three days of talks in Amsterdam with India's Federal Minister Oscar Fernandes and New Delhi's main peace interlocutor K. Padmanabhaiah.
"The government of India has failed to make their point explicitly clear on our demand for a special federal arrangement that allows us self-governance," Chawang added in a telephone interview.
"Such insensitivity by New Delhi will jeopardize future peace initiatives," he said, warning that "the Nagas are getting restless."
There has been no official statement from New Delhi after the Amsterdam talks.
The NSCN-IM, led by guerrilla leaders Isak Chishi Swu and Thuingaleng Muivah, has warned of serious consequences if India refuses to accede to its demand for the creation of a "Greater Nagaland", which aims to unite 1.2 million Nagas living in the region.
But the demand, which would involve slicing off parts of the neighbouring provinces of Assam, Manipur and Arunachal Pradesh, is strongly opposed by the three states.
The NSCN-IM and New Delhi are currently observing a ceasefire first reached in August 1997. The truce is subject to annual renewal and the current deadline expires in June 2007.
India and the NSCN-IM have held at least 50 rounds of peace talks in the past nine years to end one of South Asia's longest-running insurgencies.
"The government of India is trying to tire out the Nagas by dragging the peace process," the rebel leader said.
The Naga insurgency has claimed around 25,000 lives since India's independence from Britain in 1947.
