Donors and investors were told the bill to replace housing and infrastructure destroyed by the conflict will amount to $88.2bn by Iraqi officials at an worldwide conference held in neighbouring Kuwait on Monday (12 February).
Qusai Abdelfattah, director general at the planning ministry, said USD22 billion of those funds were needed immediately and the rest for the medium term.
In accordance with this, Foreign Minister Mevlüt Çavuşoğlu, who is scheduled to attend the Kuwait International Conference for the Reconstruction of Iraq, will announce Turkey's major projects for Iraq today.
It will cost nearly $90bn (£65.1bn) to rebuild war-torn Iraq after three years of bitter fighting with Islamic State (Isis).
Large parts of Iraq's second-largest city, Mosul, are still in ruins, more than six months after it was retaken by the government.
"We have more than 138,000 houses damaged, more than half this number completely destroyed", Hiti said, adding that more than 2.5 million Iraqis are still displaced.
However, the USA government is not expected to pledge direct financial aid at the conference.
He said that broad participation in these events gives it a great importance and is a message from the worldwide community regarding its commitment to the security and stability of Iraq and its commitment to the reconstruction of its liberated areas.
Housebuilding is the most urgent task for Iraq, said Raja Rehan Arshad, the lead disaster risk management specialist for the World Bank.
French Foreign Minister Jean-Yves Le Drian, whose country is a key member of the anti-IS coalition, visited Iraq on Monday ahead of attending the conference.
"I have come to tell you of France's support and to accompany you".
A USA -led invasion toppled Saddam Hussein and was followed by years of insurgency, sectarian bloodletting between Sunnis and Shi'ites, as well as ethnic tensions between the Arabs and Kurds, all before ISIL emerged in 2014. We will always be there.
"The majority of the damage was to western Mosul as it went through one of the worst and fiercest battles in history", said Nofal al-Akoub, the governor of Iraq's Nineveh province. We were there to participate in the coalition.
It was at war with Iran for most of the 1980s, and its invasion of Kuwait in 1990 led to war with a USA -led coalition and more than a decade of worldwide sanctions.
NATO Secretary-General Jens Stoltenberg said the alliance was ready to answer a USA call for it to expand its small training mission in Iraq to support reconstruction. It fought Iran for most of the 1980s and invaded Kuwait in 1990, leading to defeat by a USA -led coalition and more than a decade of sanctions.
