Sudan will revise oil transit fee demand in talks with South

* Sudan, South Sudan resume talks on oil payments

* First round since border fighting escalated in April

ADDIS ABABA, July 25 (Reuters) - Sudan will revise its

transit fee demand for South Sudan's oil exports when the

African neighbours resume talks to end an oil dispute for the

first time since border fighting escalated in April, a Sudanese

official said on Wednesday.

The U.N. Security Council has given the foes until Aug. 2 to

end all disputes or face sanctions. The neighbours came close to

a war in April when their armies fought for weeks along the

disputed border, the worst violence since South Sudan's

secession a year ago under a 2005 peace agreement.

The African Union has been trying to mediate but both

countries remain at loggerheads over where to mark the disputed

border and how much landlocked South Sudan should pay to export

oil through the north.

Both countries will be discussing on Thursday South Sudan's

oil payments at talks in Addis Ababa, the first time since the

South briefly occupied the Heglig oilfield in April which

contributed much to Sudan's oil output.

Juba shut down 350,000 barrels per day output in January

after Khartoum started taking some oil for what it called unpaid

transit fees.

South Sudan said on Monday it was willing to pay $9.10 and

$7.26 per barrel to transport oil through two pipelines passing

Sudan alongside a $3.2 billion dollar package to compensate for

the loss of most oil reserves to the north.

This offer is higher than before but still well below

Sudan's last demand of $36 a barrel for both pipelines.

"Our position will be developed in accordance with the new

position that has been presented by South Sudan in their

comprehensive paper," said Mutrif Siddiq, spokesman for Sudan's

negotiations team in Addis Ababa.

"Our paper is going to be revised accordingly and we'll see

where we meet and where we differ and we'll try to approximate

the differences as much as we can through the discussions that

will take place tomorrow," he said when asked whether Khartoum

was willing to lower its demand.

Oil provides about 98 percent of South Sudan's income. Juba

is trying to develop infrastructure and institutions devastated

by a war that killed an estimated 2 million people.

The latest round of talks, mediated by former South African

President Thabo Mbeki, have broken down several times over where

to set up a demilitarized border buffer zone - seen as a first

step to ending hostilities.

Sudan has said it wants to make border security a priority

at the talks. It accuses Juba of supporting rebels in two border

states, a claim denied by South Sudan.
