"We salute all initiatives seeking to create an atmosphere of confidence, if Iran's rights to peaceful nuclear activities are recognised," the speaker of Iran's parliament said in Moscow, responding to an AFP question on Russia's face-saving plan.

But, "during my visit, the question of uranium enrichment in Russia was not mentioned concretely," Gholam Ali Haddad Adel told a press conference in the Russian capital.

The existence of the Russian plan had not previously been confirmed by Tehran.

The Iranian speaker also noted that Russia's construction of a nuclear station at Bushehr is in line with IAEA standards, charging the United States with "solely political" motives in opposing it.

"We know that objections posed by the Americans to our cooperation, particularly concerning Bushehr, are solely political," he said.

Russia is currently helping Iran build the Bushehr nuclear power plant and earlier this month signed an agreement on supplying Tehran with sophisticated TOR M1 mobile surface-to-air missile defence systems.
