The leaders of the frontline Naga separatist group, National Socialist Council of Nagaland (Isak-Muivah), NSCN (IM), today met the Home Minister Mr. P Chidambaram in New Delhi. The meeting assumes significance as they have been invited by the government for peace talks. The rebel group's chairman Isak Chisi Swu and general secretary T. Muivah arrived in New Delhi Saturday night from self-imposed exile in the Netherlands. They are set to hold talks in the afternoon with the government's new interlocutor R. S Pandey, former petroleum secretary and former chief secretary of Nagaland . AIR correspondent says that NSCN (IM) wants greater Nagaland with the Naga dominated areas in the neighbouring states of Assam, Manipur and Arunachal Pradesh to be included in it. This is, however, opposed by these states .The last round of peace talks between the government and the separatist group held in March 2009 in Zurich, Switzerland ended stalemate. The NSCN-IM had entered into a ceasefire accord with the Indian government in August 1997. They have held 67 rounds of talks with the government so far.
