Russia exports a large percentage of its gas, oil, and coal to the EU, with Ukraine controlling much of the pipeline infrastructure from Russia to Europe. This creates an interdependent relationship where disputes over gas prices and debts have led to crises affecting Russian and European gas supplies. Future pipelines like Nord Stream and South Stream aim to diversify supply routes, while Nabucco could transport gas without relying on Russia. For Ukraine to utilize its strategic position, it must address domestic problems like corruption and inefficient energy management.
