Executive chairman Garry Cook claims the former Thailand prime minister is not looking for a buyer for City.
He told BBC Radio Manchester: "When these things get thrown at you, you actually try that much harder.
"He (Thaksin) is even more adamant now, because this is his love, and he wants to show people he is really committed.
"I asked the question as well as everyone else - 'is the club for sale?' and he is quite adamant this club is not for sale and he is here for the long haul.
"I asked 'why did you buy it?'. He said he bought it because there is a 10-year plan."
