"The agreement is not necessary," Kadyrov said. "We propose to forget about this agreement. I am against its signing."
Last month, the Russian parliament's upper house rejected a similar agreement between the central government and the Volga area republic of Tatarstan.
The agreement stipulated that the federal government and Tatarstan's Cabinet negotiate a deal allowing Tatar authorities to have a greater say in decisions involving economic, environmental, cultural and other regional issues.
The document also guaranteed that a leader of Tatarstan, whose candidacy is proposed by the Russian president, must speak the Tatar language in addition to Russian. The republic would also have the right to issue internal identification papers, with an insert in Tatar.
