BUDAPEST, May 22 (Reuters) - Hungarian oil group MOL said on Friday that it has received approval from the U.S. Treasury's Office of Foreign Assets Control (OFAC) to continue talks until June 6 on the purchase of a majority stake in Serbia's Russian-owned oil firm NIS.
"We entered into the final phase of these very complex negotiations. We are optimistic, however, certain terms and conditions remain to be finalized over the coming weeks," Zsolt Hernadi, Chairman and CEO of MOL Group said in a statement.
The deadline for talks expired on Friday.
