Five Irish MEPs have signed a motion calling for all European Union ports to be closed to Russian vessels.
The MEPs also want an embargo on Russian energy imports, exclusion of all Russian banks from SWIFT and the sanctioning of individuals as named by Russian opposition leader Alexei Navalny.
The plant is partially owned by Russian billionaire Oleg Deripaska who has been sanctioned by the UK and is under threat of sanction by the EU.
It is owned by the Russian State Transport Leasing Company.
The vessel made a previous attempt on March 2nd to berth at Foynes to take on board a shipment from the plant.
A cargo vessel, the Pola Varvara, sailing under the Russian flag arrived in Dublin Port on Tuesday morning.
It is registered to the Russian government-owned State Transport Leasing Company. It has since left Dublin to return to Russia.
Such a sanction was necessary, she suggested, to stop a Russian government “that tortures and kills innocent children and civilians what the world has recently witnessed in the town of Bucha”.
She urged the EU to go further and impose sanctions on Russia which include the closure of all member states ports to Russian shipping.
She said: “Thus, Russia must be deprived of all resources. First of all, financial and economic ones. The European Union must finally adopt a principled decision and close ports to Russian ships, to stop the transit of goods and any economic activity with Russia.”
The ambassador said the EU sanctions placed on Russia to date “are not enough”.
