(CNN) - Donald Trump responded Monday to Mike Huckabee's suggestion that he serve as treasury secretary, predicting who would be hurt most by the potential appointment.
"I'll tell you, it would be very painful for China, it would be very painful for OPEC, it would be very painful for many of the countries that are just ripping us off," the real estate mogul said on Fox News.
Former Arkansas Gov. Huckabee, who first made the suggestion last week, reiterated his call Monday morning, saying current Treasury Secretary Timothy Geithner has "failed the economy and failed this president."
"The president needs to have him walk the plank, if not for policy reasons, he needs to do it for the political optics," Huckabee said on Fox News. "And bringing Donald Trump in is a real optical game changer."
Geithner announced Sunday he would remain in his post through the 2012 election.
Although Trump seemingly dismissed the suggestion, he showered Huckabee, the former 2008 GOP presidential candidate, with praise.
"I think he would have gotten the nomination personally [in 2012], but you know he had lots of considerations," Trump said. "So, he said that, I'm greatly honored."
Huckabee and Trump decided against bids for the White House earlier this year after public flirtations. Criticism of China and OPEC were oft-heard lines from Trump as he traveled to early presidential voting states mulling a bid.
