"This agreement is considered an integrated and aggravated theft and can only be described as a deal between thieves who are stealing and thieves who are buying, constituting an assault against Syria's sovereignty," the Syrian Foreign Ministry said in a statement carried by the state news agency SANA.
The "null and void" deal is "a continuation of the US hostile approach toward Syria" by "stealing the resources of the Syrian people and hindering the efforts of the Syrian state to rebuild what has been destroyed by terrorism that is mostly backed by the US government itself," the ministry statement added, Xinhua reported.
Syria's oil and gas fields are largely concentrated on the northeastern part of the country, especially in the provinces of Hasakah and Deir al-Zour which are largely controlled by the Kurdish-led forces.
The news and analysis website Al-Monitor reported on Thursday that the agreement was inked in mid-July “with the knowledge and encouragement of the White House.”
The deal is aimed at marketing oil in the territory controlled by the US-backed entity and developing and modernizing existing fields.
