BRUSSELS, July 16 (Reuters) - The European Union told member states on Thursday to store more natural gas to ensure they are ready for any new suspension of supplies by Russia.

Setting out new gas security rules, the executive European Commission said the 27-nation bloc ought to have enough natural gas in storage to cope with a crisis of up to 60 days.

"Europe must learn the lessons of previous crises and make sure that European citizens are never again left in the cold," European Commission President Jose Manuel Barroso said.

EU Energy Commissioner Andris Piebalgs said Slovenia, Lithuania and other Baltic states had the most to do, and Denmark, Germany and Greece were among the best prepared.

About one fifth of EU demand is satisfied by Russian gas that flows through pipelines in Ukraine, whose payment difficulties have increased fears supplies could be cut again.

"Where are the biggest challenges? It's the Baltics," Piebalgs said. "The two countries where the biggest investments need to be made are Lithuania and Slovenia."

"The easiest steps are for Denmark, but Greece is also doing quite well," he added. "Germany is fine. Belgium is doing fine -- those countries that have decent storage capacity."

COMMUNITY EMERGENCY

Under the new rules, the European Commission would declare a "Community Emergency" if the EU lost more than 10 percent of its gas imports. EU countries would then have to help each other by ensuring unhindered flow of gas across their borders.

By the end of March 2014, member states will have to ensure their infrastructure is sufficiently diversified to deal with a cut of up to 60 days in freezing weather.
