RUSSIA

Europe has imposed the toughest sanctions against Russia since the Cold War, sending the rouble into a tailspin and prompting warnings that British firms will be hit hard.

EU leaders have agreed to embargoes against vast sectors of the Russian economy, designed to cripple its banks, energy firms and defence capabilities.

The most drastic measure will prevent Russia’s banks from issuing stocks or bonds in Europe, potentially forcing them into the arms of the Russian state for support.

Nearly half of the bonds issued by big state-run Russian lenders are in European markets. There will also be a blanket ban on all future arms sales to Moscow.

Another eight names of individuals and three firms will be added to an EU blacklist, meaning they will be subject to asset freezes and travel bans. Of those, four are described as personal ‘cronies’ of President Vladimir Putin.

President Barack Obama said the US has also expanded sanctions against Russia. He added: ‘If Russia continues on this current path, the costs on Russia will continue to grow.’ EU leaders said Russia would be shown that ‘destabilising Ukraine, or any other Eastern European neighbouring state, will bring heavy costs to its economy’.

‘Russia will find itself increasingly isolated by its own actions,’ they added. ‘Illegal annexation of territory and deliberate destabilisation of a neighbouring sovereign country cannot be accepted in 21st-century Europe.

‘Furthermore, when the violence created spirals out of control and leads to the killing of almost 300 innocent civilians in their flight from the Netherlands to Malaysia, the situation requires and urgent and determined response.’

The rouble crashed to its lowest level since early May against the dollar as leaders prepared to implement the new sanctions.

Downing Street conceded that the British economy, particularly financial services, would suffer.

BP warned sanctions could ‘adversely impact our business.’ BP has a 20 per cent stake in Russian energy giant Rosneft.

Moscow is likely to retaliate , with one group of Russian lawmakers suggesting banning international accounting firms and consulting groups from the country. Targets were said to be Deloitte, KPMG, Ernst & Young, PwC, Boston Consulting Group and McKinsey. David Cameron said: ‘We want to make it clear that Russia’s behaviour in destabilising another country – Ukraine – is unacceptable.’

In another dramatic escalation of tensions between Russia and the West, Mr Obama has accused Putin of conducting tests in violation of a 1987 nuclear missile treaty.

Mr Obama wrote to the Russian leader protesting about a breach US officials described as ‘a very serious matter’.
