Russia will continue to seek a political resolution to the dispute over Iran's nuclear program, the Foreign Ministry said Wednesday. Foreign Ministry spokesman Mikhail Kamynin spoke a day after Iran submitted its written response to a package of incentives offered by the United States and five other world powers including Russia if Iran rolls back on its nuclear program. "The Russian side has started studying the Iranian reply along with its partners in the sextet," Kamynin said in a statement. "Russia will continue with its course of searching for a political solution ... and will continue to seek to preserve the role of the International Atomic Energy Agency and prevent the erosion of the non-proliferation regime." Iran said Tuesday it was ready for "serious negotiations" on its nuclear program, insisting it was not trying simply to buy time to develop weapons. But a semiofficial news agency said the government was unwilling to abandon uranium enrichment - the key US demand.
