According to RIA Novosti, the department noted that the certification of the gas pipeline will not pose a threat to gas supplies to Germany.
"The Federal Ministry of Economy in its analysis comes to the conclusion that the issuance of the certificate will not jeopardize the security of gas supply to Germany and the EU," the ministry said in a statement.
The construction of the Nord Stream 2 gas pipeline was fully completed on 10 September.
The first line was filled with technical gas.
In early October, the Russian Foreign Ministry noted that the procedures for certification of the gas pipeline are underway, but it is difficult to foresee what "legal squiggles" could be used by opponents of this project.
