TEHRAN, April 15 (Reuters) - President Mahmoud Ahmadinejad said on Wednesday Iran had prepared proposals to end a stalemate over its nuclear ambitions with six world powers, state television reported.

"We have prepared a package that can be the basis to resolve Iran's nuclear problem. It will be offered to the West soon," Ahmadinejad said in a televised speech in the southeastern province of Kerman.

The United States, Russia, China, France, Germany and Britain said last week they would ask European Union foreign policy chief Javier Solana to invite Iran to a meeting to find "a diplomatic solution to this critical issue".

It marked a significant shift in U.S. policy under President Barack Obama, whose predecessor George W. Bush shunned direct talks with Tehran as long as it pressed ahead with uranium enrichment that the West fears is meant to yield atomic bombs.
