Uncertainty as US, S. Korea Enter New Round of Defense Cost-Sharing Talks Kelly Kasulis SEOUL - The United States and South Korea will begin its fourth round of negotiations over military defense cost-sharing in Washington, D.C. Tuesday after a breakdown in talks last month. Jeong Eun-bo, South Korea's top envoy for the negotiations, touched down in Dulles International Airport, outside Washington, on Monday ahead of the Tuesday and Wednesday talks. He expressed optimism in comments at the airport, despite the fact that U.S. negotiators cut short talks on Nov. 19 after representatives from both countries couldn't find common ground. "There were areas that didn't go as planned, but because the two countries still share an understanding of the South Korea-US alliance and the strengthening of the joint defense posture, I believe we will be able to produce a win-win result if we continue discussions with patience," Jeong reportedly said on Dec. 2. There is pressure to strike a deal, with the two countries' current cost-sharing agreement slated to expire by the end of this year. Around 28,500 U.S. troops are currently stationed in South Korea, and Seoul already agreed to increase their share of the cost burden by 8.2% last February. That brought South Korea's total contribution to around $808.5 million -- which is about half of the total cost -- but now, Washington negotiators say they want even more. During negotiations in Honolulu last October, the U.S. asked South Korea to pay about $5 billion -- roughly five times the current agreed-upon amount -- starting next year. .
