The government held a series of foreign affairs and security meetings to discuss countermeasures after the North Korean army threatened Sunday to expel all "unnecessary" South Korean personnel from its Mount Geumgang resort area.

Unification Ministry spokesman Kim Ho-nyoun said Sunday the government is disappointed by North Korea's move as well as its lack of a response to Seoul’s calls for investigations into the shooting death of a South Korean tourist at the resort.

The spokesman said Pyongyang has no right to expel South Korean personnel, as it is a violation of a bilateral agreement for South Korean tours to the North Korean mountain.

Kim also stressed that additional safety measures should be taken for South Korean tourists in Gaeseong, another attraction in the North.

As of Sunday, a total of 262 South Koreans were working at Geumgang.

Meanwhile, Pyongyang has not issued an official order of expulsion yet.
