MOSCOW, June 15 (Reuters) - Russia is not discussing plans for a Syrian political transformation following the exit of President Bashar al-Assad, Foreign Minister Sergei Lavrov said on Friday, emphasising Moscow's strong opposition to external interference.
Russia and China, both permanent members of the U.N. Security Council with veto power, have blocked efforts by Western powers to condemn Assad and call for his removal during 15 months of bloodshed.
Western nations want Russia to abandon support for Assad and have held intensive diplomatic discussions with Moscow in recent weeks, as persistent violence has undermined hopes that envoy Kofi Annan's U.N.-backed peace plan can end the violence.
At a news conference after talks with his Iraqi counterpart, Lavrov said he had seen reports saying U.S. State Department spokeswoman Victoria Nuland had suggested Washington and Moscow were discussing a post-Assad strategy in Syria.
"If that was really said then it's not true," Lavrov said. "Such discussions are not being held and cannot be held, because to decide for the Syrian people contradicts our position completely.
"We do not get involved in overthrowing regimes - neither through approval of unilateral actions by the U.N. Security Council nor by participation in any political plots."
Nuland was asked at a news conference on Thursday whether the United States and Russia were discussing a transition of power similar to that seen in Yemen last year, in which President Ali Abdullah Saleh was replaced by a deputy.
"We are continuing to talk about a post-Assad transition strategy in that context," she said.
Lavrov said any broad international talks on Syria must include Iran and must only address ways to create conditions for a political dialogue in Syria - not the content of that dialogue or preconditions such as Assad's exit.
Russia, which has come under increasing criticism from the West for arms deliveries to Syria, responded to U.S. Secretary of State Hillary Clinton's allegations that attack helicopters were on the way from Russia to Syria.
In a statement on the Foreign Ministry website, Russia said it had made no new deliveries of military helicopters to Syria but under old contracts it had repaired helicopters sent to Syria "many years ago".
"There are no new deliveries of Russian military helicopters to Syria. All arms industry cooperation with Syria is limited to a transfer of defensive arms," the ministry said on its website.
"As regards helicopters, planned repairs of (helicopters) delivered to Syria many years ago were conducted earlier," it said. It did not say when they had been repaired or, if they were repaired in Russia, when they were returned to Syria.
Syria's ambassador to Russia said on Thursday Russia had not sent new attack helicopters to Syria.
Russia says it is fulfilling existing contracts for air defence systems against external attacks. President Vladimir Putin, due to meet U.S. President Barack Obama next week, said the weapons Russia sends could not be used in civil conflicts.
A source close to Russia's arms exporting monopoly Rosoboronexport said Clinton's comments may have referred to helicopters sent to Russia in 2009 for repairs and which may be on the way back to Syria.
The source said on Wednesday at least nine Mi-25 helicopters were sent to Russia's Baltic exclave of Kaliningrad to be repaired by Oboronservis, owned by the Defence Ministry.
Russia delivered three different missile systems including Bastion anti-ship missile units and another anti-aircraft system to Syria last year.
At least two ships carrying Russian weapons have reportedly travelled to Syria since the beginning of the year, though possibly not on behalf of state arms exporter Rosoboronexport. (Additional reporting by Nastassia Astrasheuskaya and Steve Gutterman; Editing by Andrew Roche)
