More than 5,000 volunteer workers played a key role in the nation’s successful hosting of the G20 Seoul Summit, which ended Friday.

A total of 5,829 volunteer workers, 74 percent of whom were women and 26 percent men, were dispatched before and during the Seoul summit, city officials said.

Youngsters in their 20s made up the largest portion, at 69 percent, followed by teenagers at 20 percent. 

Those aged over 50 accounted for 2.5 percent. Jung Gi-sik, an 80-year-old former international financier, was the oldest volunteer.

The volunteer workers, most of them offering foreign language services, worked in some 30 fields such as transportation guidance, cultural and tourist information, lodging and other administrative support.

Transportation volunteers offered guidance at 110 subway stations throughout the city, while culture volunteers introduced the city’s history and culture at popular tourist spots for international visitors and press.

Some foreign volunteers also offered information in their mother tongue.

“We will support the 5,000 volunteers in order to create advanced citizenship and the city’s positive image,” said a city official.
