Despite the suspension of deliveries from the Russian company, negotiations are still ongoing, Topchiyski said. 

"We don't know how the correspondence will develop, but there is a possibility of a resumption of supplies. It is about the contract we have until the end of the year. Hypothetically, it is possible that they will change their terms. We do not close the page as long as there are guarantees that there will be no risks for Bulgargaz if the conditions change," said Topchiyski. 

According to him, about 60% of the gas needed by Bulgaria for the winter months has been agreed, together with the agreed 7 tankers from the USA.
