Iraq, whose plans to rebuild after years of war have been undermined by a collapse in oil prices, could get a boost from joining the World Trade Organization (WTO), a top official said.

Iraq "has all the components to be able to accede" to the Geneva-based multilateral body,Trade Minister Abdul Falah al-Sudany said in a statement after a meeting with U.S. officials in Baghdad.

A ministry spokesman said he expected all the issues standing in the way of Iraq joining the global trade body to be settled witin two years, after it has had time to redraw the centralised economy created under Saddam Hussein.

"Iraq cannot be closed. The world now is a small village," the spokesman said.

Violence has dropped sharply in Iraq, but Prime Minister Nuri al-Maliki's government is increasingly alarmed about the impact of a drop in oil prices on plans to provide essential services and create jobs.

The price of oil, which accounts for more than 95 percent of government revenues, has fallen by more than $100 from a record $147 per barrel last July.

A steady stream of oil dollars will be key to paying police, paving streets, boosting power supplies -- all crucial to ensuring Iraq does not return to the horrific violence of the years since the 2003 U.S.-led invasion.

According to the WTO, Iraq applied to WTO membership in 2004, and the last meeting of a working group on joining it was held in April 2008.

The spokesman said a new round of talks was planned but gave no dates.
