Hyundai Engineering and Construction has won a 1.3 billion US dollar contract with an electricity company in Libya.
According to Seoul's foreign ministry this is the first large-scale contract between the two countries since the strained Korea-Libya relations were normalized this month.
Hyundai is set to receive a 15-percent advance this week and break ground for construction next month.
The two countries' relations had gone sour back in June, when a Korean intelligence agent was deported from Libya for collecting off-limit information.
The de facto Libyan embassy in Korea will resume its suspended operation on Friday, at the earliest.
