Re risk:
If say Bank of China did the Due Dilligence and gave the green light to provide sufficient funding, and Shen is committed to the deal, plus more than 75% shareholder vote in his favour? Can anyone enlight me that in what way could the deal fall over? I was aware that previously the funding structure is not stated so clear so that it may not be funded by BOC, this time it is different, BOC won't pull the funding after DD.
