KIEV, June 1 (Reuters) - Russian gas transit through Ukraine dropped by 46% in January-May to 20 billion cubic meters (bcm), Ukrainian state-run gas transit operator said on Monday.
Russian and Ukrainian gas firms signed a five-year deal in December safeguarding the transit of Russian gas to Europe via Ukraine, following five days of painstaking talks and a meeting between Russian and Ukrainian leaders.
The operator said this year the transit could fall to an all-time low of 52-55 bcm. Last year, the gas transit totalled almost 90 bcm. (Reporting by Pavel Polityuk)
