The U.S. is replacing its chief negotiator for defense cost talks with South Korea.
The previous Senior Advisor for Security Negotiations and Agreements, Jim Dehart, has taken up a new role as the U.S. Coordinator for the Arctic Region.
Dehart had led the negotiations over the defense cost-sharing agreement with South Korea since last September.
Dehart's replacement has not been announced yet, but the State Department said it is focusing on reaching a mutually acceptable agreement with South Korea.
In the previous round of talks in March, the two countries had tentatively agreed on a 13 percent increase, but that was rejected by President Trump, who is still looking for a much larger increase in South Korea's contribution.
