TRIPOLI, July 7 (Xinhua) -- The head of the Libyan High Council of State on Saturday requested French President Emmanuel Macron to communicate with all Libyan parties to stop "violation" of the Paris agreement.

"While we were waiting for the implementation of what has been agreed upon by the parties concerned, including working to end parallel institutions, we are surprised by the transfer of the oil ports to a parallel and illegal body," Khalid al-Meshri said in a letter to Macron.

France hosted in May a meeting on Libya with the participation of different Libyan parties to end the political crisis in the country.

The parties agreed to hold and commit themselves to "credible" presidential and parliamentary elections slated for Dec. 10.

Al-Meshri said the transferring of the oil ports is a violation of the Paris agreement and several UN Security Council resolutions, which "emphasize the need for the Government of National Accord to have the sole effective control over the National Oil Corporation."

"We hope you would communicate with the Libyan parties to immediately stop these violations and move to what was agreed upon," al-Meshri said in the letter.

The Libyan eastern-based army, led by Gen. Khalifa Haftar, recently took control of the oil crescent region, which is located some 500 km east of the capital Tripoli and contains the country's largest oil ports, after defeating the militants occupying it.

Shortly after that, the army handed over the region to the National Oil Corporation of the eastern-based interim government, instead of the Tripoli-based UN-backed unity government.

The UN-backed government warned against "negative repercussions" of suspension of oil exports in the oil crescent region, saying halting oil exports could cost more than 67 million U.S. dollars a day.

Despite signing a UN-sponsored peace agreement by the Libyan political parties in 2015, Libya remains politically divided between eastern and western governments, both competing for legitimacy.

Oil-rich Libya has been plagued by insecurity and chaos since the 2011 uprising that toppled former leader Muammar Gaddafi's regime.
