ATHENS, Oct 9 (Reuters) - Serbia's Russian-owned NIS NIIS.BEL oil company has failed to secure another waiver from U.S. sanctions, the company said on Thursday.
"The special license from the U.S. Department of the Treasury, which enables seamless operational business, has not yet been extended," the company said.
NIS, one of Russia's last remaining energy assets in Europe, said it had secured sufficient stocks of oil for processing as U.S. sanctions take effect.
