"We've invested so far more than a billion dollar since July 2011 and plan to invest another billion," Mouayed Makhlouf, regional director for IFC in the Middle East and North Africa, said on the sidelines of a conference in Dubai.

"We're definitely starting to look at Libya, mainly financing trade," Makhlouf added.

IFC, which invests in developing the private sector in emerging economies, is looking at sectors such as infrastructure, education, financial services and trade, he added.

IFC had invested $2.2 billion in the MENA region since January last year, Makhlouf said, becoming an important conduit of capital for companies impacted by unrest in the Arab world last year.

It made a $50 million equity investment in Orascom Construction Industries and agreed to lend $200 million to its subsidiary, Egyptian Fertilizer Company in July.

IFC also agreed in December to invest up to $110 million in Jordan-based Hikma Pharmaceuticals to help improve access to high-quality generic medicines in the MENA region.

Through its IFC Capitalisation Fund, which supports emerging market banks, IFC signed a $170 million subordinated loan agreement with Oman's Bank Muscat last month.
