Cheong Wa Dae is considering using all the leverage it can in defense cost-sharing talks, known as the Special Measures Agreement. This will include expanding the "definition" of the contribution.
The National Security Council is reviewing possible participation in the U.S.-led naval mission in the Strait of Hormuz, the presidential office said in a statement. The NSC is reviewing "phased" participation such as the sending of a liaison officer or patrol boat before redeploying the Republic of Korea Navy’s anti-piracy Cheonghae unit in the Gulf of Aden.
Cheong Wa Dae also plans to link South Korea’s payment for the cleanup of contaminated former USFK bases as another "bargaining chip" to reduce the increase in Seoul’s contribution to defense cost-sharing. A senior ruling party lawmaker disclosed that the government has recently offered a revised proposal to purchase up to $1 billion worth of U.S. weapons by the end of next year.
