Japan should propose specific confidence-restoration measures to allay fears over Iran's nuclear programs, Iranian Foreign Minister Manouchehr Mottaki told visiting Japanese lawmakers Wednesday.

Mottaki made the remark when he met with Katsuya Okada, former leader of the Democratic Party of Japan, and two other lawmakers, the Japanese legislators said. They are on a weeklong visit to Iran and the United Arab Emirates.

In asking Japan to make the proposals, Mottaki stressed that Iran had suspended nuclear activities for 2 1/2 years before resuming uranium enrichment activities recently, the lawmakers said.

Okada told Mottaki that Iran should go a "step ahead" and decide to stop enriching uranium instead of arguing to bring the issue back to the International Atomic Energy Agency from the U.N. Security Council, they said.
