"If the damage is assessed monetarily it is much more than $1 billion. This is a fact," the minister said as quoted by Ukrinform.
He added that he had discussed with the European Commission whether it was possible to begin restoration works in Donbass.
"Now, we can’t do anything there. Only preparation and planning are possible. I reported to the European Commission on the possible damage in the region and in the border area so our colleagues could start considering an aid package," Pivovarsky underscored.
He noted that no concrete aid measures have been discussed.
In September 2014, the Minsk talks resulted in a series of agreements to de-escalate the conflict.
On August 26, the Minsk group held talks during which the sides agreed on a ceasefire in Donbass beginning September 1. On September 13, during his meeting with former British Prime Minister, Ukrainian President Petro Poroshenko said that the ceasefire has been observed in Donbass since late-August.
