ATHENS, Oct 9 (Reuters) - Serbia-based Russian oil

company NIS said on Thursday it had failed to secure

another waiver from U.S. sanctions, which could complicate its

long-term efforts to secure oil deliveries.

The U.S. imposed sanctions on NIS, one of Russia's last

remaining energy assets in Europe, in January, part of a wider

move to isolate Russian energy assets. But a series of waivers

delayed the measures until October 9.

"The special license from the U.S. Department of the

Treasury, which enables seamless operational business, has not

yet been extended," NIS said in a statement.

However, the U.S. on Wednesday extended a license for

Croatian oil pipeline operator JANAF, NIS' main

supplier, to continue transporting crude to Serbia for another

week, as it seeks to complete the delivery of contracted

volumes.

NIS said on Thursday it had secured sufficient stocks of oil

for processing and gas stations in the country were regularly

supplied with all types of petroleum products as U.S. sanctions

take effect and the company worked to overcome the situation

with partners, the Serbian government and shareholders.

Gazprom Neft holds a 44.9% stake, and an investment

unit of Gazprom has about 11.3% in NIS. The Serbian

government has a 29.9% stake.
