The U.S. State Department has notified Congress of plans to close five diplomatic missions as part of a broader effort to reduce costs and streamline government operations. The closures would represent a relatively uncommon reduction in the United States’ overseas diplomatic presence. Staff and responsibilities from the affected posts are expected to be transferred to other diplomatic missions in their regions. The State Department said it regularly reviews its global network to ensure resources are being used efficiently and that any changes follow the required congressional process. Supporters of the restructuring view the move as part of an effort to eliminate operations considered costly or lower priority.
