Sumitomo and Posco - Japan and Korea Sumitomo and Posco are competitors in the fiercest sense. Japan and Korea have an extremely tenuous history and their battle in the field of global commerce is just an extension of their long history.
I find it hard to believe Sumitomo would partner with Posco on anything and at any scale.
Hopefully Nano One can bridge this long history of continued competition between Sumitomo and Posco. But until I see something concrete to demonstrate that Posco and Sumitomo are now on the same side, I just find it impossible to believe.
Good luck to all the longs.
