"The two leaders… discussed shared US and EU concerns about the Nord Stream II pipeline and the need to ensure the diversification of European energy supplies," Nauert said. "They discussed the security and humanitarian situation in Syria, the importance of continued reform in Ukraine, and the common approach to ensuring a path to the final, fully verified denuclearization of the DPRK [North Korea]."
On Wednesday, the US Department of State said that any firms working in the Russian energy export pipeline sector face sanctions risk.
European Commission's Vice-President for Energy Union Maros Sefcovic said during his joint press briefing with Perry after the EU-US Energy Council's meeting in Brussels that he agreed with the US energy secretary on the issue of sanctions.
The United States, which is seeking to promote its own gas companies on the European market, has repeatedly criticized the European Union's reliance on Russian gas and threatened to impose sanctions on companies working under the Nord Stream 2 project.
In the most recent case earlier this week, US President Donald Trump said Germany’s cooperation with Russia and heavy reliance on Russian energy resources was inappropriate and called the country a "captive" of Russia. German Chancellor Angela Merkel said Berlin acted independently in its policies.
Kremlin spokesman Dmitry Peskov has said any sanctions against the companies involved in the Nord Stream 2 pipeline project will be illegal, as the project is based solely on commercial benefits and is not politically motivated.
