Kittiya Todhanakasem, a first senior executive vice-president of Krungthai Bank (KTB), said Mr Apisak, who is tipped to be the new finance minister, is suitable to rein in Thailand's economic slowdown.
Given his capabilities and good morals, Mr Apisak is an excellent choice to help turn around the economy, she said.
Mr Apisak was president of stateowned KTB for eight years before retiring in late 2012.
Prior to taking the helm at KTB, he was president of Siam City Bank, which has since been integrated into Thanachart Bank.
