LONDON, March 25 (Reuters) - The Swiss refining unit of Libyan oil company Tamoil said it was in talks to reassure clients about the impact of international sanctions on its ability to make deliveries, a spokesman said on Friday.
"There are discussions going on with certain fuel suppliers (customers), who are asking for guarantees," said spokesman Laurent Paoliello.
"We are working normally now and studying the possiblity of bringing forward maintenance to early April instead of June, allowing the situation to clear up."
BP said on Friday it was halting all business with the group and was declaring force majeure on all oil and product deliveries.
