The United Kingdom announced a massive expansion of its sanctions against Russia's oil exports. However, it notably carved out an exemption for the Druzhba pipeline, a critical oil pipeline that remains a flashpoint for European energy politics.

Marking the fourth anniversary of the invasion of Ukraine, Foreign Secretary Yvette Cooper unveiled nearly 300 new sanctions intended to cripple the revenue streams fueling Moscow's military. Among the primary targets is Transneft, the state-owned operator responsible for more than 80% of Russia’s oil exports.

However, the U.K. government’s Office for Financial Sanctions Implementation confirmed that the Druzhba pipeline—which Transneft operates—is listed as an "exempt project." 

This decision ensures that oil can continue to flow through the network, which remains a vital energy artery for Hungary and Slovakia.

The exemption comes as the Druzhba pipeline becomes a primary lever in a geopolitical standoff between Budapest and Brussels. 

While the European Union banned Russian seaborne oil in 2022, landlocked nations were granted a reprieve for pipeline imports—a loophole that Hungary has continued to utilize.

Tensions escalated this week after Hungarian Prime Minister Viktor Orbán accused Kyiv of intentionally delaying repairs to the pipeline’s Ukrainian section following a January drone strike. In retaliation, Budapest vowed to block a €90 billion (about $106 billion) EU loan intended for Ukraine.

Despite the Druzhba carve-out, the British Foreign, Commonwealth and Development Office (FCDO) maintained that the new measures would significantly hamper the Kremlin’s "desperate scramble" for buyers.

Beyond Transneft, the sanctions package also targeted Energy Infrastructure, such as the Portovaya and Vysotsk liquefied natural gas (LNG) terminals, and the Nuclear Sector, with three major nuclear energy firms already sanctioned.

The FCDO did not immediately provide a specific reason for the Druzhba exemption, though analysts suggest the move aligns with Western efforts to avoid destabilizing the energy security of Eastern European allies, even as they pressure Moscow to end the conflict.
