MOSCOW — Russian gas company Gazprom halted supplies to neighboring Ukraine today after the collapse of pricing talks, company official said.

Gazprom CEO Alexei Miller said that Russia halted the supply because Ukraine didn’t make an advance payment for July’s delivery.

“Gazprom is not going to send gas to Ukraine at any price without the advance payment,” Miller said in comments carried by Russian news agencies.

Russian and Ukrainian energy ministers on Tuesday failed to reach an agreement on future supplies. Russia offered Ukraine a price of $247 per cubic meter, a $40 discount. Ukraine wanted a $100 discount.
