Itthiporn said on Tuesday it was time for a new coalition to help push the country forward.
"Since the 2006 Constitution took effect, two elected governments have come to power but both failed to overcome the political predicament," he said.
The Air Force chief also urged political parties to put the country before partisan interests, saying the Kingdom was in a crisis so deep that governments had nothing to boast about.
Surapong said that while Itthiporn had the right to express his opinions, as a military official he should not be getting involved in politics.
"I recommend that ACM Itthiporn zip up his month because his comments could hurt people's feelings. Otherwise he should just stage a coup d'etat right away. What he said sounded good, but showed that he was not neutral."
Surapong's comments came as the Democrat Party announced plans to form a coalition government after the Constitution Court dissolved PPP and two other coalition parties last week. A Democrat-led coalition, which would have Abhisit Vejjajiva as prime minister, would not include Pheu Thai.
Pheu Thai MP Jatuporn Phrompan hit out again at Army chief Gen Anupong Paochinda, who he claimed had threatened to stage a coup if minor parties refused to endorse Abhisit as PM.
He also lashed out at Itthiporn for making "inappropriate remarks" in favour of the Democrats.
Former Thai Rak Thai Party executive Chaturon Chaisang also lashed out at the military top brass for "intervening" to break up the existing coalition and coercing the Friends of Newin faction to endorse a Democrat-led coalition.
He also said the former coup leaders had masterminded the destruction of a pro-Thaksin Shinawatra government in order to install an administration preferred by the military, the People's Alliance for Democracy and the Democrats.
Chaturon said it was too late for Pheu Thai to push for a national government because a deal had been sealed in favour of the Democrats.
