Chang Ung expressed his disappointment after the South Korean flag was mistakenly displayed on the giant screen before the women's soccer game between North Korea and Colombia in Glasgow, Scotland, on Wednesday night.
The North Koreans refused to take the field for about an hour before the match went ahead. London organizers have apologized.
Chang raised the matter at the IOC general assembly, saying "I don't think it's a big political issue."
He proposed that protocol officials meet with team leaders before each medal ceremony to "check this is your flag or this is your national anthem."
IOC President Jacques Rogge called it a "most unfortunate incident" and "a simple human mistake."
