The freshly-reelected Nursultan Nazarbayev announced his willingness to help mediate the Nagorno-Karabakh conflict.

“In 1991 I already participated in the settlement of the Nagorno-Karabakh conflict, when I saw the people’s tribulations … I would like to stress once more that interethnic conflicts between neighbours bring about only grief and unhappiness for people,” - he has said. “Therefore I am ready to participate in any quality in the settlement of the conflict between the two near peoples, between Azerbaijan and Armenia,” - N. Nazarbayev has said.

There’s something self-serving about this, of course. While BP can self-insure against the BTC attacks, Kazakhstan would prefer a more stable environment for its (President’s) oil to flow out. Since they expressed interest in transporting some oil via Azerbaijan, they acquire a stake in stability in the South Caucasus.

Here’s some history on Nazarbayev’s earlier (unsuccessful) attempt to mediate.
