Serbia is caught in a precarious position as US sanctions against Russian oil come into effect, straining its historical allegiance with Moscow. The sanctions target the Petroleum Industry of Serbia (NIS), over 50% owned by Russian firms, creating ripples throughout the country's oil supply system.

With Serbian President Aleksandar Vucic openly voicing discontent, the situation has been exacerbated by the country's reliance on Russian gas, which is also under threat as the current agreement nears expiration. This has led to tense diplomatic exchanges between Belgrade and the Kremlin.

Dubravka Djedovic Handanovic, Serbia's Energy Minister, revealed that Gazprom, which owns a significant share of NIS, has sought a waiver from US sanctions, indicating potential shifts in ownership to stabilize operations. However, the clock is ticking, with crippling sanctions already leading to cash-only operations at gas stations.

The flow of oil via vital pipelines has been disrupted, compelling Serbia to seek alternative energy solutions rapidly. Not only does this crisis threaten Serbia's immediate fuel supply, but it also raises concerns about the future of employment for thousands of workers connected to NIS.

This energy dilemma underscores the broader geopolitical shifts in the Balkans, as neighboring countries also adapt to similar sanctions, reflecting a complex interplay of energy dependency and international diplomacy.
