According to him, Poland emphasized from the very beginning that European solidarity in this area should be unequivocal.
“Therefore, if such needs from the German side are declared, then Poland is open to use the infrastructure that it is building for its energy security,” RIA Novosti Mueller quotes.
He noted that the Polish side approaches energy security "in solidarity" and believes that it should be built with a common European approach.
“It's hard not to look with concern at initiatives like Nord Stream 2, which run counter to the idea of solidarity and energy security,” he added.
