Security is still a major concern at the Olympic Games despite unprecedented precautions, according to Park Seh-Jik, president of the Seoul Olympic Organizing Committee.

Park said Sunday he placed security on top of his worry list, followed by traffic flow and the weather."People are very security conscious and are being co-operative," he said. "I am confident there will be no incidents at all on the question of security."

He discounted any danger from people entering from the North carrying diplomatic status.

"There are many kinds of people, some normal and some insane, but we have very reliable security agencies and they can be checked in advance."

The Koreans were working closely with other countries on security.

"These agencies are collaborating all the time and pass on information," he said.

Park said traffic congestion will be eased by restricting private motorists to using their cars on alternate days.

He was not overly concerned about student protests. "Most people support the Olympic Games, but everyone has a right to protest, providing they abide with the law. I just hope they will not damage the mood of festivity," he said.

Park believed the staging of the Games had changed South Korea's political face.

"The Olympic Games was a decisive momentum for the people on the road to full democratisation. Leaders of the four or five political factions are more friendly to each other now than they were four years ago."
