From page 49:
RECOMMENDATION 5: The Support Group should consist of Iraq and all the states bordering Iraq, including Iran and Syria; the key regional states, including Egypt and the Gulf States; the five permanent members of the United Nations Security Council; the European Union; and, of course, Iraq itself. Other countries—for instance, Germany, Japan and South Korea—that might be willing to contribute to resolving political, diplomatic, and security problems affecting Iraq could also become members.
