The U.S. House of Representatives has approved an amendment that would impose new sanctions on companies assisting Russia in completing a controversial gas pipeline to the European Union bypassing Ukraine.

The United States opposes the project on the grounds that it strengthens the Kremlin’s grip on the European energy market and punishes Ukraine, which is battling Russian-controlled forces in its eastern region of Donbas.

The project “Nord stream-2” is more than 90 percent built. It consists of two parallel lines running under the Baltic Sea, each 1,230 kilometers in length. The nearly $11 billion “Nord Stream-2” pipeline, which would have an annual capacity of 55 billion cubic meters a year, would largely reroute gas to Europe around Ukraine, depriving Kyiv of billions of dollars in annual fees.
