Speaking at a marriage function here, Jayalalithaa said the Centre has remained silent on convening the Cauvery River Authority meeting and it was only at the intervention of the Supreme Court that the state got "some" water from Karnataka.
"The Centre continues to reduce the quantum of kerosene and snatch powers of the states. The state gets only routine acknowledgement from the Prime Minister for the problems raised," she said.
She said the Centre refused to allocate additional power to the state by adopting a "negative approach". It was adopting a similar approach on the Mullaperiyar Dam issue, over which the state is locked in a row with Kerala.
"We have to overcome all these hurdles and challenges. I am working with a resolve to secure the states' rights," she said pledging to achieve them with people's support.
