KYIV, July 7 - The Slovak side takes advantage of legal inaccuracies and believes that it is not obliged to voluntarily introduce European network codes on the border with Ukraine, in connection with which the Ukrainian side appealed to the European Commission and the Energy Community Secretariat for help in resolving the situation, Head of Gas Transmission System Operator of Ukraine LLC (GTSOU) Serhiy Makogon said.

"After Ukraine and the EU jointly implemented European legislation on the Ukraine-Russia border, the situation with manual and non-transparent distribution of capacities on the Ukraine-Slovakia border looks extremely strange," he wrote on his Facebook page.
