JUBA Sudan (Reuters) - South Sudan said on Monday that the central government had stopped paying its share of oil revenues in foreign currency, creating a foreign exchange crisis in the region ahead of a January vote on independence.
Under a 2005 north-south peace deal which ended a two-decade long civil war, the south receives about 50 percent of Sudan's oil revenues. The oilfields are in the south but all the ports and refineries are in the north, so wealth-sharing is likely to continue even if the south votes to secede on January 9.
The semi-autonomous South Sudan government derives some 98 percent of its budget from oil revenues, making its economy almost totally dependent on the cash sent from the north.
David Deng Athorbei, the south's finance minister, said the decision to pay its oil revenues in local Sudanese pounds since July was a "sinister" ploy to unsettle the south's economy.
"This is a clear attempt to violate the CPA (peace accord)," Athorbei said. "It is an attempt by NCP (the north's ruling party) to stifle the southern Sudanese economy".
He said the north had taken similar action in June 2008, but the dispute had been resolved through political dialogue. Reuters Africa
