Deputy Minister for Temporary Occupied Territories and Internally Displaced Persons Heorhiy Tuka has said that if there is evidence of shipping coal from the Ukrainian temporarily uncontrolled areas in Donetsk and Luhansk regions to Russia, this could be a reason for filing lawsuits to international courts.

"These events are not in line with international requirements. If we have a chance of receiving photos of high resolution, including photos of crossing the state border and if these facts are recorded, this is a reason for filing claims… We do not have facts, only statements in media," he told reporters on Saturday in Kyiv.

He said that each deposit, in particular, coal deposits, has their own specifics.

"It is impossible to present coal extracted in Donbas as coal extracted, for example, in Kemerovo," Tuka said.

He also said that any foreign economic transactions meeting international requirements are to be carried out with permits.

"If goods do not have permits, this is smuggling. If it is coal extracted on the Ukraine temporarily uncontrolled area, this could be war crimes that would be evidence of plundering of natural resources of Ukraine," he said.

Tuka said that law enforcement agencies are to tackle these facts.
