RE:Horrible deal for Giga.To me sounds like Mitsuibushi knows exactly what it is doing.
Takening a substantial ownership position for almost nothing. They know a big partner will need to come in and do the development of this project.
It has been published previously that phase 1 alone is 1.5 billion and phase 2 of another minimum .5 billion
They are just keeping a nose in with the hope something works out over time and their 15% will give them future leverage if anything interesting develops.
