Denmark is considering ways to limit the passage of tankers carrying Russian oil from flowing through the Baltic sea.
Speaking today, the Nordic's country's foreign minister, Lars Lokke Rasmussen, has brought together a group of allied countries to evaluate the outcomes of the move.
Russia sends about a third of its seaborne oil exports - which equates to around 1.5% of global supply - through the Danish straits.
This passage acts as a gateway to the Baltic Sea, so any attempt to halt supplies would send oil prices higher and hit the Kremlin's finances.
The move could trigger confrontation with Russia, though it's something that Denmark has been preparing for.
Earlier this month, the country raised the threat level for destructive cyberattacks against companies and authorities, saying Russia was showing an increasing willingness to take risks to carry out hybrid attacks.
Its government has also asked citizens to prepare for an attack or other potential crisis by stockpiling supplies of water, food and medicine.
