"The EU only supports those projects that do not contradict the basic principles of the Energy union. Diversification of energy sources, suppliers and supply routes are essential to ensure safe and resistant to disruption supplies [of energy] to European enterprises," Maroš Šefčovič said.
"Therefore the Nord Stream 2 does not stir common interest and will not be funded from the budget of the European Union," he added.
According to the European Commissioner, the Russian gas pipeline will not provide the EU access to new sources of gas.
"In this case, we will be rather focusing on closer cooperation with Russia in terms of gas supplies," he said.
Maroš Šefčovič also noted that Ukraine proved to be a reliable transit partner last winter in terms of delivery of Russian gas.
