The document discusses two competing gas pipeline projects - Nabucco and South Stream - between Europe and Russia. It analyzes the challenges facing both projects, including differing partner priorities, uncertainty around gas supply sources, and political issues between countries. Key problems highlighted are the high costs of Nabucco, lack of a confirmed gas supply, and tensions between Turkey and Russia over the South Stream project. The document suggests potential solutions could involve concessions between EU, Russia and Ukraine to reduce unnecessary competition between the two pipelines.
