On Sunday, the government of South Korea announced that it was extending its air defense zone to include Socotra Rock, a submerged pinnacle in the Yellow Sea. The Korean air defense zone now overlaps with the air defense zones already claimed by both China and Japan and is expected to increase tensions in the region. Both Korea and China had already claimed the rock as part of of each countrys’ “exclusive economic zones,” (EEZ).
