South Korea says it will act if fuel shipments to Russia broke the law

South Korea says it will pursue legal action if fuel shipments from its ports to Russia are found to have violated domestic law. The government is now investigating the cases.

The response follows a Guardian report that thousands of tonnes of fuel were transported to Russia. A joint statement from the foreign ministry, the trade ministry and the customs service said officials are "checking additional information" about the loading cases the Guardian reported.

The statement said that if the verification finds laws and regulations were violated, the government plans to act in accordance with the law.

Al Jazeera reports that Ukrainian claims of South Korean fuel exports to Russia come at a time of strained relations between Seoul and Kyiv.
