Starting in August, certain military conscription candidates will find their ability to travel overseas restricted.

It's part of a new, tighter set of rules to prevent young men from avoiding or delaying military service.

The Military Manpower Administration says conscription candidates aged 25 to 27 will only be able to travel overseas for less than six months at a time, for a maximum of five times within a two-year period.

Also, candidates aged 28 and above will no longer be able to delay their conscription due to enrollment in graduate school, having a sibling doing his military service, or working as an honorary ambassador for a region or agency.

Local entertainment industry officials oppose the changes, saying the toughened rules may have an adverse impact on overseas activities of the "hallyu" or Korean wave stars.
