Arunachal Congress (Mithi), was a break-away group of Arunachal Congress. AC(M) was formed in 1998 when Mukut Mithi led a revolt against the AC leader Gegong Apang. AC(M) gathered 40 (out of 60) Members of the Legislative Assembly of Arunachal Pradesh and one of the AC members of the Lok Sabha, Wangcha Rajkumar. AC(M) formed a new state government, with Mithi as Chief Minister. In 1999 AC(M) merged with Indian National Congress.
Whatever be the Congress' interpretation, the fact remains that the BJP has succeeded in making inroads into the Congress bastion by winning nine seats, when it failed to win a single seat in the 1999 Assembly elections despite a poll alliance with Gegong Apang-led ArunachalCongress.
Congress sources said that Mithi lost his bargaining power to stake claim to the chief ministership as only six of his 16 hardcore loyalists, known as "super sixteen" in party circles, could win.
Arunachal Pradesh is considered the powerhouse of the country with a hydropower potential of 49,000 MW.
Arunachal Pradesh borders the state of Assam to the south and Nagaland to the south east.
Arunachal Pradesh is one of two main disputed regions between India and China, the other being Aksai Chin: the People's Republic of China does not recognize the state of Arunachal Pradesh, nor the McMahon Line.
The PRC regards most of the territory administered by Arunachal Pradesh as Chinese territory occupied by India, and splits the area nominally among six border counties of the Tibet Autonomous Region: (from west to east) Cona, Lhünzê, Nang, Mainling, Mêdog, and Zayü.
