The China-based forward, who played his last game for South Korea in a World Cup qualifier two years ago, was named by coach Huh Jung-moo for a May 16 home friendly with Ecuador.
"Every match will be competitive and a scorer will be important," Huh told local media on Saturday. "We have Ahn Jung-hwan, Lee Dong-gook and Park Chu-young to score goals."
Ahn, South Korea's answer to David Beckham, cemented his place as a national idol during South Korea's barnstorming run to the semi-final of the 2002 World Cup and also found the net at the 2006 finals in Germany.
The 34-year-old, now playing for Chinese side Dalian Shide, was named with several European-based players including captain Park Ji-sung of Manchester United, Park Chu-young of Monaco and Bolton's Lee Chung-yong.
"Our team is as strong as any other team in the World Cup," said Huh. "All the players have confidence and fighting spirit. They have a dream and passion and are ready to display their combative spirit."
Former Fulham forward Seol Ki-hyeon, who had recently recovered from knee surgery, was a notable omission, but the Pohang player could yet make Huh's final 23-man World Cup squad.
South Korea face Greece in their opening Group B match on June 12 before playing Argentina and Nigeria.
