Mueller said that the Council of the European Union has the competence to impose sanctions on certain products.
According to him, such a decision on Russian propane-butane was not made, so there is no ban on its import.
"In this regard, if it comes to decisions regarding the ban on the import of LPG gas, then we expect that it will be solidary within the framework of all countries of the European Union," RIA Novosti quoted him as saying.
Earlier it became known that the Polish energy concern Orlen is exploring the possibility of demanding compensation from Russian companies for the cessation of oil and gas supplies.
Igor Yushkov, a leading analyst at the National Energy Security Fund, said in an interview with RT that Poland is trying to present Russia as an unreliable supplier.
Later, the Polish company EuRoPol GAZ filed a lawsuit against Gazprom in the amount of $ 1.4 billion.
