This was stated by the adviser to the President of the United States for national security Robert O'Brien.

“We call on all parties - both those responsible for the current escalation and those working to end it - to allow the National Petroleum Corporation to resume its vital work with full transparency, to implement the demilitarization decision for Sirte and El -Jufry, respect the UN arms embargo and finalize the ceasefire within the framework of military negotiations under the auspices of the UN in the 5 + 5 format, ”RIA Novosti quoted him as saying.

He noted that the United States is "against foreign military involvement."

“Continued attempts by foreign powers to exploit the conflict — for example by establishing a permanent military presence or establishing control over resources that belong to the people of Libya — are a major threat to regional stability and world trade,” O'Brien said.

Earlier, The Wall Street Journal, citing its sources, said that the US authorities had threatened the commander of the Libyan National Army, Khalifa Haftar, with sanctions for allegedly obstructing oil supplies from Libya.
