Russia to Ukraine: Fuhgeddabout it!

We hope Greece isn't planning on asking Russia for any help either, not after this;

Russian gas company Gazprom has halted all natural gas supplies to Ukraine after Kyiv failed to make an advanced payment for July. Kyiv revealed on Tuesday it would suspend Russian gas purchases.

Russia is up front about it; pay rubles up front. And so is Ukraine; Nyet.

Ukraine has said it will now exclusively buy gas from Slovakia.

No room for sentiment in business.
