This project is impossible without Kazakh oil. But Nazarbayev doesn't hurry to transport his oil via Caspian sea, Azerbaijan and Georgia. He prefers Russian pipelines.
Nazarbayev is a smart dictator, I must admit. He is playing on both sides for sure. The most profitable solution for him is diversification. Now is looking how the world treat Aliev of Azerbaijan and see that they are willing to close their eyes for oil deliveries. Such solution would be ideal to Nazarbayev. There is no reasonable cause why would he prefer only Russian pipelines. Im sure that he dislike monopolistic practices of Russia. Kazakh delegation is present in every meeting about new oil projects, for example on the ceremony of opening Baku-Ceyhan pipeline. In the internet English language Kazakh state owned media outlets I noticed many articles about meetings of Polish or Ukrainian diplomats with their Kazakh counter-partners. Kazakh side always claim to be interested in our project. I believe if they are any problems it is rather on our side
