TODAY: Putin fails to apologise for airplane tragedy; Obama calls for Putin intervention as rebels hand over MH17 black box; unpredictability of Ukraine crisis scares investors; new sanctions threatened as officials say existing restrictions may affect Rosneft privatisation plans; Germany says sanctions affect its companies; Severstal pulls out of U.S. market.

President Vladimir Putin came somewhat close to apologising for the Malaysian Airlines plane crash in his conciliatory video statement yesterday, making vague statements about how the tragedy should bring people closer together, and that the event should not be used as a platform for political spectacle.  But not close enough, says The Times: ‘The “s” word is difficult for Russians, as it implies for them a loss of face.’  The downing of the plane ‘gives the lie to the idea that Mr. Putin is some kind of strategic genius,’ says the Financial Times, listing a series of what it sees as the President’s ‘blunders’ regarding Ukraine.  Mary Dejevsky says the crash must have been ‘an acute political embarrassment’ for Putin.  U.S. President Barack Obama is urging Putin to intervene directly with rebels to ensure cooperation with the investigation, promising Russia’s further isolation if a diplomatic solution to the Ukraine crisis is not found.  Following 12 hours of negotiations, the black box recorders from flight MH17 were handed over to Malaysia by the leader of the pro-Russian separatists in Donetsk, who again blamed the Kiev government for the crash.  Russian print media have continued also to make similar allegations.  The unpredictability of Russia’s situation – and fear of an open war with Ukraine – is spooking investors, says Reuters.
