Seoul: Some 360 cars will speed into the venue of the Seoul nuclear summit at exactly one-minute intervals - not a second more and not a second less.
A rehearsal was held for escorting world leaders from 53 countries and four international organisations who attend the two-day Nuclear Security Summit.
The Chosun Ilbo reported that some 360 cars will be used.
Hyundai Equus limousines are for heads of states while BMWs are for their entourage and other delegates.
The protocol team will ensure that the cars arrive at exactly one-minute intervals. If there is a delay of even a few seconds, the tightly scheduled plan of action could be thrown out of gear.
The world leaders are spread out in 12 five-star hotels in central Seoul. And to manage them, there are 116 diplomatic liaison officers.
