Russia-US ties more important than Snowden 'squabbles': Putin

President Vladimir Putin today said Moscow's relations with Washington outweighed the 'squabbles' over fugitive US intelligence leaker Edward Snowden, who has applied for asylum in Russia.

But Putin also defended Moscow's right to an 'independent' foreign policy after the United States renewed calls for the extradition of Snowden, who is seeking to evade espionage charges for leaking details of a vast US surveillance programme.

'Relations between states are much more important than squabbles surrounding the work of security services,' Putin said after overseeing military exercises in the far-flung eastern Siberian region of Chita.

Snowden, a former National Security Agency contractor, has been marooned at Moscow's Sheremetyevo airport since June 23 after revealing that Washington has been seizing huge amounts of Internet and telephone data around the world.

'Russia has an independent foreign policy and we will follow it,' Putin said in televised remarks.

'We cannot and will not behave like other countries,' he said, in an apparent reference to an incident earlier this month when several European countries closed their airspace to Bolivian President Evo Morales's plane amid speculation that Snowden was on board.

The latest flare-up in ties between Moscow and Washington comes as Putin is set to host US President Barack Obama for a hugely sensitive bilateral summit in Moscow followed by the G20 summit in Saint Petersburg in early September.

The White House has voiced strong opposition to Snowden's request for a safe haven in Russia and has criticised Moscow for providing the 30-year-old with a 'propaganda platform'.

'We believe there is ample legal justification for the return of Mr Snowden to the United States, where he has been charged with serious felonies,' White House spokesman Jay Carney said yesterday.

'We want to continue (the US-Russia) relationship unimpeded by this issue,' Carney said. 'And we believe there is a way to move forward here that allows for Mr. Snowden to return to the United States... And for Russia to resolve this situation that they have been dealing with now for three weeks.'

Yesterday, Snowden, whose US passport has been revoked, filed an application for temporary asylum with the Russian migration service, starting a process that could take up to three months.

He has indicated he eventually wishes to travel on to Latin America.

A request for temporary asylum is handled by Russia's Federal Migration Service and does not require Putin's approval.

But Putin reiterated his stance that Snowden would only be welcome to stay in Russia if he did not harm the United States with further leaks.
