MOSCOW, June 7. /TASS/. Russia's gas giant Gazprom has received a letter from Ukraine’s Naftogaz requesting resumption of natural gas supplies, Chief Executive Officer of the Russian gas holding Alexey Miller said on Tuesday.

"We have indeed received a formal letter from the Chief Executive of Naftogaz of Ukraine with a request to resume natural gas supplies. Nine months are meant: the second half of 2016 and the first quarter of 2017, that is, the forthcoming winter and the preparation period. The change in Ukrainian company’s mood is understandable. Daily reverse from Europe dropped 6.4 times in June as compared to May and 16.8 times vs. April," Miller said.
