I would think the way the Chinese were embarrased by recent insider events spinning a story to force SDL hands is not in their fit.
Looks like a genuine 57c bid
Suggest in this market its a great offer
A 60c bid nicer but the world is in a very scary place at the moment
I would imagine without Hanlong bidding we are well below 30c, and any JV would not be on 50/50 terms more like 30/70 in this climate
