Russia's gas monopoly Gazprom says it has resumed supplies to Ukraine that will help the country meet its energy needs through the harsh winter months.

Gazprom CEO Alexei Miller said supplies, which were suspended in the spring, recommenced earlier Monday after the company received $234 million in prepayments from Kiev.

The deal, which was signed last month with the help of the European Union, will ensure that Ukraine will receive Russian gas for six months through March 2016.

Past gas disputes between Russia and Ukraine have led to cut-offs of supply. One standoff in 2009 caused serious disruptions in shipments EU countries in the dead of winter.

Russia's annexation of Crimea from Ukraine and its support for separatist rebels in the east soured relations between the two countries.
