South Korea is reportedly offering to purchase up to $1 billion in U.S. weapons systems by the end of 2020 as part of ongoing military cost-sharing talks with the United States, The Korea Times reported Dec. 12, citing anonymous South Korean officials. The purchases could include surveillance aircraft and the joint development of an anti-missile system, but they stop short of additional acquisitions of F-35 fighter jets. Separately, reports suggest that South Korea may be willing to shoulder the costs of environmental remediation at long-shuttered U.S. military bases after long resisting the proposal.
