"UOKiK issued a decision to extend by four months the deadline for the completion of the procedure for the creation of the six-party joint venture responsible for the construction and operation of Nord Stream-2," the statement reads.
The antitrust regulator received an application to create the Nord Stream-2 AG joint venture in mid-December.
"It is necessary for a careful examination of the impact of the transaction on the Polish oil market, including to analyze the opinions of the participants and the gas market regulator," UOKiK said in the statement.
Ukraine, Latvia and the Czech Republic share Poland’s opposition to the northern gas pipeline over fears it could increase energy dependence on Russia. German energy officials and business leaders have reaffirmed their interest in the project, saying it would ensure European energy safety and security.
