From sovereign nations in the Middle East - Iran’s neighbors. If you have reporting that specifically indicates international corporations or particularly American corporations (even if “undisclosed”) I particularly like to see it - and probably scoff at the “sources say” attribution. But can you please give me the source or sources you’re referring to?
And - to be clear - the statement that several sovereign nations would invest funds in redevelopment was made BEFORE this MoU even happened. The MoU language is to LET them do it.
Numerous news reports on this. Just Google it.
FYI the funds are coming from parties in the U.S., Gulf states, Asia, South America, and Africa.
As with most funding, this fund will likely grow considerably over time.
