Had it only said "recalled" without the further information further on, I would have said that he had been (possibly temporarily) removed from the post. However, the fact that someone else has now been elected to the post means that Choe Hui Gong has indeed been permanently removed. I'm not sure I would necessarily use "dismissed" as that terminology fits better with a paid position in a private company.
If he has been given a different position, you could say he "Choe Hui Jong was moved/transferred from his post of chairman of the Budget Committee to secretary of the Employment Committee".
