U.S. sanctions over the Nord Stream 2 natural gas pipeline are not a friendly action and they will draw a response, said Russia’s president on Thursday.
"We will respond based on the principle of reciprocity," Vladimir Putin told his annual year-end news conference in Moscow, APA reports citing Anadolu.
He said the U.S. sanctions over the pipeline would affect bilateral relations between Moscow and Washington.
The U.S. Congress on Tuesday approved a defense budget including sanctions on companies involved in Nord Stream 2 project.
The Nord Stream project -- operational since 2011 with an annual capacity of 55 billion cubic meters -- brings Russian gas directly to Germany via the Baltic Sea.
The Nord Stream 2, spearheaded by Russia's state-owned energy company Gazprom, is nearly finished and has the same annual capacity, running almost parallel to the first pipeline route.
Together they will meet the annual gas demands of a quarter of the European continent.
