South Sudan's President Salva Kiir Mayardit will visit Sudan on Wednesday to launch the exportation of his country's oil from Port-Sudan, Khartoum's Almeghar Al-Siasi daily reported Sunday.

"South Sudan's President Salva Kiir Mayardit will arrive in Khartoum next Wednesday to launch the arrival of the south's oil at Port-Sudan harbor and discuss outstanding issues with Sudanese President Omar al-Bashir," the paper reported, quoting an unnamed official source.

Kiir will be accompanied by South Sudan's petroleum, finance, defense and interior ministers, the paper said.

The same paper quoted Sudan's Petroleum Minister Awad Ahmed Al- Jaz as saying on Wednesday that South Sudan's oil had reached the main processing station at Sudan's Higleg oil field, and was "now on its way to the export harbors in Port-Sudan."

Khartoum and Juba used to dispute over fees which the north said the south should pay for exporting its oil through Sudanese infrastructure. In January 2012, Juba decided to halt oil pumping after Khartoum reportedly started deducting oil for what it claimed as payment of use of its infrastructure.

In a bid to thaw ties, the two sides signed in March in Addis Ababa an agreement of modality to implement the security arrangement as well as the cooperation deal reached in Ethiopia in September last year.

They further agreed to resume South Sudan's oil exportation through Sudan's pipeline
