The West's plan to starve Russia of resources by imposing a price cap on its oil exports hit a diplomatic logjam in Brussels on Friday.

Poland does not think the $60 a barrel ceiling is low enough and has refused to back the plan, preventing the European Union from adopting the measure.

On Thursday evening, several European diplomats said the other 26 member states were ready to nod the plan through in time for it to go into effect on Monday along with an EU embargo on Russian crude.
