WikiLeaks released a confidential cable on U.S. Assistant Secretary Philip Gordon’s July 3 meeting of European Union political directors in 2009.

“Resolving Nagorno-Karabakh is the key to unlocking Turkish-Armenian relations and consequently regional energy supplies,” Gordon said.

According to the document, Gordon stressed Moscow’s significant role in the Karabakh conflict resolution.

“The Russians have been reasonably productive on this account, but it is unclear whether they are just going through the motions or are seriously engaged, particularly as a Nagorno-Karabakh solution would facilitate a Southern Corridor gas route,” Gordon stressed.

According to the released document, the high-ranking diplomats had a controversy over the issue.

In response, EU Council Secretariat Director General Robert Cooper asserted that if the Russians really wanted to resolve Nagorno-Karabakh, they would have done so already.
