Rio said Nagaland Assembly had thrice adopted resolutions favouring integration of Naga-dominated areas in Manipur, Arunachal Pradesh and Assam with Nagaland.
"Naga people wants integration of Naga areas. It will bring peace," he told reporters after a meeting with Home Minister Sushilkumar Shinde.
Nagaland's neighbouring states Manipur, Arunachal Pradesh and Assam are vehemently opposed to any move for integration of Naha-inhabited areas, a demand raised by Naga insurgent group NSCN(IM) which has been engaged in peace talks with the government.
"I have urged the Home Minister to offer a package of solution to NSCN(IM) so that it can discuss the offer with Naga civil society. It will help in bringing a solution," he said.
National Socialist Council of Nagaland-Isak Muivah had entered into a ceasefire with the Centre in 1997. So far, over 60 rounds of talks have taken place between NSCN-IM leaders and the Centre's representatives.
