The head of the Libyan National Accord government, Fayez al-Sarraj, said that Libya does not have common borders with the UAE, and that this raises his government's question about Abu Dhabi’s goals in his country.

Al-Sarraj asked in an exclusive interview with Al-Jazeera that will be broadcast later, about the reasons that the UAE is establishing a military base on Libyan soil.

He added that his government has a cautious optimism about the results of the Berlin conference, given the previous experiences, as the reconciliation government did not find a reliable partner to get out of the crisis.

But Al-Sarraj added that it is hoped that the parties supporting the retired Major General Khalifa Hifter will review their accounts regarding the Libyan issue.

On the oil issue, the head of the Al-Wefaq government said that Libya would face a catastrophic situation if Haftar forces continued blockade of the oil fields, expressing his hope that foreign powers would press Haftar to reopen the oil ports soon.

Al-Sarraj announced his rejection of Haftar's demands linking the reopening of ports to the redistribution of oil revenues, and said he would respect the Berlin conference’s call for a ceasefire and political talks, but he would not sit with Haftar again.

And Reuters reported - based on a document sent to dealers and seen by the agency - that the National Oil Corporation in Libya announced the state of force majeure regarding crude loading from the Spark and Elephant oil fields.

The document said that individuals, under the supervision of the oil facilities guards, closed pipelines connecting the Sharara field to the Zawia oil port, and the elephant field with the port of Mellitah.

Most of the Libyan oil wealth is located in the east of the country, but it is the National Oil Corporation - based in Tripoli - that distributes revenues and says it is to serve the entire country, and that the corporation is not related to the conflict between the factions.

Diplomats said the parallel government in the east of the country had repeatedly sought to export oil, bypassing the National Oil Corporation, but the United Nations had banned it.

The corporation sends oil and gas revenues - the economic lifeline in Libya - to the central bank in Tripoli, which mainly works with the Saraj government. The government divides revenue between paying salaries, fuel subsidies, and other services, including the areas controlled by Haftar in the east of the country.
