The two Koreas will hold a dedication ceremony Friday for a joint office to oversee the building of a family reunion center at the North Korean mountain resort.

The event was agreed on at last month's prime ministerial talks and the ninth South-North Red Cross meeting.

Two hundred South Koreans will attend, including Unification Minister Lee Jae-joung, National Red Cross chief Han Wan-sang and Hyundai Asan Chairwoman Hyun Jeong-eun. The North will send a hundred delegates including senior Cabinet councilor Kwon Ho-ung and North Korean Red Cross President Jang Jae-un.

The office's resident staff will support reunion events at the mountain resort, expanding reunions and making them possible at any time. They will also oversee cross-border talks on various forms of separated family exchanges.

Construction of the reunion center began in August 2005 after it was agreed upon two years earlier in inter-Korean Red Cross talks. Now 68 percent complete, it is slated to open in the first half of next year.
