North Korea is expected to inspect a golf course and the Onjeonggak recreation complex in Mount Geumgang on Tuesday as part of its probe into South Korean real estate holdings at the resort.

A Unification Ministry official in Seoul said Tuesday that three officials from Emerson Pacific, which owns the golf course in the mountain resort, entered the communist state via an overland route for the investigations earlier in the day.

Earlier on March fourth, the North unilaterally notified the South of its plans to conduct an investigation on South Korean properties in Mount Geumgang and threatened to take special measures, including seizing South Korean properties, if Seoul failed to resume tours to the mountain resort.

The North's probe is considered to be an attempt to force South Korea to lift its ban on the tours it imposed following the South Korean tourist who was shot and killed by a North Korean soldier at the resort in the summer of 2008.

The North’s probe is set to conclude Wednesday.
