European Union leaders reached a deal late Monday on a sixth sanction package that would include a partial oil embargo against Russia after resolving an objection from Hungary.

During a marathon meeting in Brussels, the EU members agreed to an embargo that covers Russian oil transported by sea, allowing a temporary exemption for imports delivered by pipeline.

EU Council President Charles Michel said on Twitter the deal covers more than two-thirds of oil imports from Russia, “cutting a huge source of financing for its war machine. Maximum pressure on Russia to end the war.”

The package had stalled in recent days as Hungarian Prime Minister Viktor Orban  repeatedly claimed his nation’s economy would shatter without oil from Russia, which supplies 60% of Hungary’s oil. All 27 EU countries must agree for the package to win approval.

As a landlocked nation, Hungary is not impacted by the ban on oil brought in by tanker.

European Commission President Ursula von der Leyen had expressed doubt that an agreement would be reached at the two-day summit. “My expectations are low that it will be solved in the next 48 hours,” she said.
