The U.S. military in South Korea fully returned its former base, Camp Market, to the Asian country Wednesday, the defense ministry said, as part of a broad relocation scheme to consolidate its bases across South Korea.
The U.S. Forces Korea (USFK) handed over about 257,000 square meters of land in Camp Market near Seoul to South Korea, four years after returning some 216,000 square meters of land in the base in the first phase.
The agreement was made in a meeting of the South Korea-U.S. Status of Forces Agreement Joint Committee, which governs the legal status of the 28,500 American soldiers stationed in South Korea.
“As the rest of the site of Camp Market, which was used for a bread factory and warehouse, has been returned, the return process of a total of 473,000 square meters of land has been completed,” the defense ministry said in a joint statement with the ministries of foreign affairs, environment and land.
