Due to ethnic Koreans living on the island at the time of a 1962 border treaty, both China and North Korea agreed that the sovereignty of the island belongs to North Korea. The former river island is now a North Korean exclave on the otherwise Chinese side of the river.[2] The agreement is not recognized by South Korea, who continues to claim this island in accordance with its constitution.
History
In June 2011, an agreement, negotiated by Gao Jingde, of Sunbase International Holdings Ltd,[3] with China was made to establish a joint free-trade area on Hwanggumpyong and Wihwa Islands, as well as the Chinese border area near Dandong.[4] By 2013, the site had been prepared, and a free-trade area of over 300 acres (120 ha) may be ready for operation in about two years.[5]
