In July 1997, as a freshman at Dongguk University, Park got his first call-up to the South Korea national baseball team for the team's five annual friendly matches against the USA national baseball team in California, United States.

In July 1998, as a sophomore, Park was selected for the South Korean national team again, and participated in the 1998 Baseball World Cup. South Korea eventually claimed the silver medal two times in a row, and Park led the team attack alongside cleanup hitter Choi Hee-Seop, going 17-for-41 (.415) with 10 runs. In November, Park was called up to the South Korean national team for the 1998 Asian Games, which included professional players for the first time ever. He led his team to their first Asian Game gold medal, going 10-for-23 (.435) with a home run and 3 RBIs as a leadoff hitter.

In September 1999, Park was selected by the South Korean national team to compete in the 1999 Asian Baseball Championship. He was one of the only four amateur players on the roster. Team Korea won their two consecutive Asian Championship, and Park served as a backup center fielder to Lee Byung-Kyu in the tournament. In November, Park competed for the South Korea national baseball team, which exclusively consisted of college players, in the 1999 Intercontinental Cup. South Korea finished disappointing 7th in the competition, but in their first game of the round-a-robin tournament, Park led his team to a memorable 4-3 victory over eventual winner Cuba, smacking a two-RBI single to tie the game up at 3-3 in the bottom of the eighth inning. It was South Korea's first victory over Cuba at the major international baseball competitions organized by the IBAF.
