Deputy Chairman of Russian energy giant Gazprom Alexander Medvedev said Monday the delay pushed the launch date back again.
"We expect a full, consistent and timely fulfillment of all agreements on construction and exploitation of the first Turkish Stream string. We expect a prompt restart of negotiations, including on the inter-governmental draft agreement, which was submitted to the Turkish side for approval in May," the ministry said in a statement.
Implementation of the gas pipeline is a priority in Russian-Turkish relations, the ministry stressed.
Earlier in September, the Russian Energy Ministry said it expected an intergovernmental deal on the Turkish Stream gas pipeline to be signed after a new government is formed in Turkey in November.
The Turkish Stream is a proposed pipeline with an annual capacity of 63 billion cubic meters running from Russia to Turkey beneath the Black Sea. The pipeline will continue to a hub on the Turkish-Greek border, from where it can be extended to southern Europe.
