SEOUL -- South and North Korea have agreed to revive reunions of divided family members this month after a visit to Pyongyang by a special envoy from the South resumed dialogue between the nations, the Korea Red Cross said on Sunday.

Under the agreement, 100 Southerners will visit the North's Kumgang mountain resort for three days starting on April 28 and 100 North Koreans will come to an undecided venue in the South in the following three days, the agency said in a statement.

The exchange of elderly Koreans, which was originally scheduled for last October but halted by the North, was resumed after South Korean Special Envoy Lim Dong-won visited Pyongyang last week, Reuters reported.

In unusually candid remarks, Lim said on Sunday he had taken a long and detailed letter from President Kim Dae-jung to North Korean leader Kim Jong-il during his visit.

Lim's talks, including five hours with Kim Jong-il, yielded a resumption of stalled North-South exchanges and helped set the stage for what would be the first full-scale dialogue between Pyongyang and the administration of U.S. President George W. Bush.

South Koreans have been cut off from relatives and ancestral graves in North Korea since the 1950-53 Korean war. The two Koreas have remained in a technical state of war because they never signed a peace treaty.
