WASHINGTON: The United States said on Thursday it made some progress in two days of talks with Russia over a disputed US missile shield to deter attacks from states like Iran, but big differences remained.

The latest talks in Washington followed a visit last week to Moscow by US Secretary of State Condoleezza Rice and Defence Secretary Robert Gates, who offered to give Russians access to US-proposed shield sites in the Czech Republic and Poland as a way of allaying Russian fears over the plan.“We made a lot of headway ... but there are still significant issues that need to be resolved,” Acting US Undersecretary of State for Arms Control and International Security John Rood told reporters at the end of the talks.

Both sides discussed written proposals on missile defence and other key bilateral issues delivered by Rice and Gates at the end of their Moscow trip.

Washington wants to get a so-called strategic framework agreement on key issues between the two countries in time for a summit next month between US President George W. Bush and outgoing Russian President Vladimir Putin, but US officials conceded there was a way to go yet.

Asked whether he thought the strategic framework document, which includes missile defence, would be agreed on before the Putin-Bush summit, senior State Department official Dan Fried told reporters: “I don’t know.”

“They were not going to give away positions where they had disagreements, but they were not throwing up roadblocks and spinning things out,” Fried added.

Rood said they were working at an ‘intense’ pace, but he was noncommittal over when there might be agreement.

“I often find it difficult to predict when my counterpart will finally reach a meeting of the minds with me. It is always a difficult challenge,” he said.

The US plan to place parts of a missile defence system in formerly Soviet-allied countries has been a major factor in the deterioration of US-Russian relations in recent years.

The dispute has pushed diplomatic relations to a post-Cold War low, although trade has been unaffected.

Washington says the system is needed to protect against growing capabilities of ‘rogue’ states like Iran, but Moscow says the system could threaten Russia.

The latest American proposals under discussion are meant to convince Moscow that the missile defence system in Eastern Europe would not be directed against Russia, US officials said.

Bush, whose term ends in January 2009, is set to meet Putin in early April in Sochi, following a Nato summit in Romania, which both presidents are set to attend,

“It is important that both countries complete a presidential transition that is Russia and us. We thought it was important to have this (strategic framework) document as a positive platform in the US-Russian relationship as we go forward,” Fried said.

Putin is set to hand over the presidency to his successor Dmitry Medvedev on May 7. Putin is expected to become prime minister in the new government and will likely have broad powers in his new role.
