The European Union is threatening to block Russian membership of global free trade agreements unless President Vladimir Putin pledged to "de-escalate" a deepening crisis between Moscow and its neighbors, The Daily Telegraph wrote on May 4.
The paper claims that secret EU documents reveal patience in Europe's capitals is running out with Russia amid spiraling trade disputes and attacks this week on Estonian diplomats in Moscow.
NATO joined the EU yesterday in registering a formal diplomatic protest over Russia's failure to protect Estonian embassy staff from marauding demonstrators with close political links to Mr Putin.
The row has been escalated by a Russian rail blockade of oil and coal exports to Estonia, a development that will harden EU resolve to take a tough line on Moscow's ambition to membership of the World Trade Organization (WTO).
The showdown will take place at a EU-Russia summit in the Russian city of Samara on May 18 and European diplomats are ready to read the riot act to Mr Putin over a growing number of disputes.
These include cuts to Lithuania's oil supply, dual pricing for international and domestic rail cargo, export duties on wood and a ban on Polish meat imports.
