Talks ended with Kiev demanding contract changes to bring down the highest prices in Europe for Russian gas supplies, and Moscow suggesting its proposed cut of about one-fifth to around $385 per 1000 cubic metres was its final offer, Reuters reported.

The dispute is part of a broader stand-off between Ukraine and its former Soviet master, as Kiev's new West-leaning leadership struggles to contain a pro-Russian separatist rebellion in its eastern provinces.
