Andhra Pradesh ministers from Telangana are staunchly opposing any "special package" for the region in lieu of a separate state.
In a frontal attack, Congress president Sonia Gandhi on Sunday said the Telangana Rashtra Samithi played opportunistic politics over the formation of Telangana state, and had joined hands with communal forces in the past.
It is the only project in the world which can lift two TMC of water every day, the government said.
The Telangana Rashtra Samithi would seek to befriend Prime Minister-elect Narendra Modi and Bharatiya Janata Party-led National Democratic Alliance government to forge a good and healthy relationship, and would not be confrontationist with the successor state of Andhra Pradesh but would fight tooth and nail for the rights of Telangana, a key party figure said on Monday.
