The rival Koreas agreed on Wednesday to hold a reunion later this month for families separated by the 1950-53 Korean War - the first such event for more than three years. Seoul and Pyongyang said they would hold the meeting from Feb 20 to 25, three days later than agreed before, according to local media reports.

The agreement came after Red Cross officials from both sides held talks at the border village of Panmunjom to sort out details, including the reunion date and venue. The delegates met at Tongilgak, an administrative building on the Democratic People's Republic of Korea's side of the truce village.

On Jan 24, the two Koreas agreed on the reunion of war-divided families at the DPRK's scenic Mount Kumgang resort.

The agreement marked a rare moment of cooperation between the two sides, especially coming just weeks before Seoul kicks off joint military exercises with the United States that have been vehemently denounced by Pyongyang.

"We hope that the latest agreement will be smoothly carried out to ease the suffering and pain of separated families," the Republic of Korea's Unification Ministry said.

Any sign of accord between tends to be greeted with optimism.

However, both sides have been here before, and observers warn that setting dates does not necessarily mean the event will take place.

The two Koreas had agreed to hold a reunion last September but, even as the chosen relatives prepared to make their way to Mount Kumgang, Pyongyang cancelled at the last minute, citing "hostility" from Seoul.

And there are widespread concerns that the families could end up being disappointed again, given the unresolved tensions surrounding the ROK-US military drills that are scheduled to begin late February.

The DPRK has warned of dire consequences if the exercises go ahead, while Seoul and Washington have dismissed any possibility of their cancellation.

The annual drills are always a diplomatic flashpoint on the Korean peninsula, and resulted last year in an unusually sharp and extended surge in military tensions.

Yoo Ho-yeol, professor of DPRK Studies at Seoul's Korea University, said that Pyongyang might use the reunion agreement as a bargaining chip.

"Rather than canceling the event again, it may try to extract concessions, like a scaling down of the joint military exercises," Yoo said.

US defense officials have already indicated that - unlike the 2013 drills - this year's version would not involve an aircraft carrier or strategic bombers.

60 years, little contact

Millions of Koreans were separated by the 1950-53 war, and the vast majority have since died without having any communication at all with surviving relatives.

Because the Korean conflict concluded with an armistice rather than a peace treaty, the two Koreas technically remain at war and direct exchanges of letters and telephone calls are prohibited.

Up to 73,000 ROK citizens are wait-listed for a chance to take part in one of the reunion events, which select only a few hundred participants at a time.

The reunion program began in earnest in 2000 following a historic inter-Korean summit. Sporadic events since then have seen around 17,000 relatives briefly reunited.

But the program was suspended in 2010 following the DPRK's shelling of an ROK border island.

Pyongyang wants Seoul to resume regular tours to Mount Kumgang, which had provided a valuable source of hard currency in the past.

Seoul suspended the tours after a woman tourist was shot dead by DPRK security guards in 2008, and it has repeatedly rejected any efforts to link their resumption to the family reunion issue.

Pyongyang is also pushing for a resumption of Six-Party Talks on its nuclear program - a long-stalled process involving the two Koreas, China, Japan, Russia and the United States.

Seoul and Washington insist substantive dialogue can only begin after Pyongyang demonstrates a tangible commitment to abandoning its nuclear weapons program.

Past family reunions have been hugely emotional - almost traumatic - affairs, with many of the elderly participants breaking down and sobbing as they cling to each other.

The events typically last several days and the joy of the reunion is tempered by the pain of the inevitable - and this time permanent - separation at the end.
