Anyone know about the International Economics Olympiad (IEO)?

Has anyone heard about the International Economics Competition (IEO)? Is it as valuable or prestigious as IMO, IPO, or ICO? Looks like it’s a pretty new competition with a strong Russian background, is it worth joining? How does it compare to other econ competitions like the NEC? How about compared to different Summer Programs like LBW and SSHI for T10 colleges?
