The second Energy Security Summit was held in Berlin on 27 and 28 May 2014. Key topics of the meeting included the "shale gas revolution" in the United States and the conflict in Ukraine. In his speech, Foreign Minister Steinmeier stressed the important role of energy policy for foreign and security policy. Steinmeier pushed for a European Energy Union and urged the EU countries to demonstrate unity with regard to the Ukraine conflict. The minister stressed the need to make compromises in the Russia-Ukraine gas dispute, and warned against too high expectations of substituting American shale gas for Russian gas supplies. EU Energy Commissioner Günther Oettinger also spoke in favor of a European Energy Union with uniform gas prices. He also described Germany's energy policy as being in a "Romantic Valley”. The strategic issue of energy would require Germany to get involved with its technological and political competence, Oettinger stated. During the meeting, Ukrainian Prime Minister Yatsenyuk described the Ukraine conflict as a "global security conflict" which only Russia would be responsible for. Yatsenyuk reiterated his country's refusal to pay a "political price" in exchange for gas supplies from Russia. The premier also expressed the willingness of his country to participate in a common energy policy with the EU.
