Ukraine has signed a major shale gas deal with Royal Dutch Shell - a move seen as an attempt by Kiev to reduce its dependency on Russian gas imports.
The contract - reportedly worth $10bn (£6bn) - was agreed on the sidelines of the World Economic Forum in the Swiss ski resort of Davos.
Royal Dutch Shell's chief executive Peter Voser told the BBC "We go where the resources are and we see a lot of potential in the Ukraine".
