Otprilike sta ce biti pogodjeno novim sankcijama, i posljedice:
Details of the EU sanctions are expected to emerge on Tuesday
but the gas sector is not affected. Major state-owned oil firms are included such as Rosneft, which is already targeted by US measures.
Russia has warned that it could block international flights through its airspace if the EU goes ahead with new measures.
Diplomats say the new package will target Russian oil companies Rosneft and Transneft and the petroleum unit of state gas monopoly Gazprom.
Their access to financial markets will be restricted - a serious matter for Rosneft, which last month asked the Russian government for a $42bn (£25.2bn) loan.

Rosneft calls itself the leader of the Russian petroleum industry. That makes it a very important player in the European Union's energy market. About 90% of the crude oil used in the EU is imported and Russia is, by a large margin, the biggest supplier.
The sanctions don't appear to directly affect that relationship. They would prevent Rosneft raising money in European financial markets.
But as crude oil is mainly transported by sea, if the trade were disrupted any losses from Russian suppliers could potentially be replaced. It would almost certainly be more expensive, but it could be done, up to a point.
Gas is another story, which may explain why Gazprom's main business is reported not to be on the new sanctions list. Russian gas is delivered to Europe by pipeline. There is a trade in gas transported by sea, but it would be very difficult to compensate for a major disruption of supplies from Russia.
The sanctions would also expand the visa bans and asset freezes on Russian officials and entities, including separatist leaders in Ukraine.
Earlier Russian Prime Minister Dmitry Medvedev warned that Moscow would respond "asymmetrically" to further sanctions.
A Russian airspace ban "could drive many struggling airlines into bankruptcy", he told a Russian daily.
