Meanwhile, Crafar receiver Mr Stiassny yesterday said he was sticking with the January 31 deadline he has set for Shanghai Pengxin to come up with an unconditional offer - which effectively means it must have OIO approval by then.
Shanghai Pengxin spokesman Cedric Allan said the company was likely to seek an extension of that deadline if an OIO decision was not forthcoming by then.
Mr Mallard said it might suit the Government to allow that deadline to pass without a decision from the OIO which must then be endorsed by ministers.
Mr Mallard this week said he understood ministers had been told Shanghai Pengxin was effectively owned by the Chinese Government.
Similarly, Mr McDonald said Sir Michael's consortium had been told by a minister that Shanghai Pengxin was "backed" by the Chinese Government.
Finance Minister Bill English yesterday would not say whether he was aware of any Chinese Government interest in Shanghai Pengxin or its offer but advised through a spokesman: "That question would be best directed to the company itself."
Mr Allan yesterday denied any Chinese Government involvement with Shanghai Pengxin and said the issue had already been extensively probed by the OIO.
But Mr Mallard said he understood the Chinese Embassy had been involved in discussions about the offer. Whether China's Government owned Shanghai Pengxin or was simply supporting its bid for the farms, it made the situation a difficult one for the New Zealand Government.
"With backing, and even more so if it's owned, it makes it harder diplomatically for people to tell them to piss off.
"Clearly the Government is under some sort of pressure, how much we don't know, but the fact that they must have knowledge of the Chinese Government's interest in it must in itself constitute pressure so they'll have that in their mind when they're making their decision."
Mr Mallard suggested Government ministers might have instructed the OIO to delay its decision until after Mr Stiassny's deadline.
"That might be the easiest way to deal with it - if it's left to Stiassny to deal with rather than the ministers."
