This bill authorizes the establishment of an Office of Export Controls and Border Security within the Department of State's Bureau of Arms Control and Nonproliferation. The Office's core mission is to advance United States foreign policy and national security objectives by enhancing the capabilities of partner countries. Specifically, it aims to protect United States-origin critical technologies and proliferation-sensitive goods and related technologies , including dual-use items, from diversion, unauthorized transfer, or misuse. The Office is tasked with supporting the development of legal and regulatory frameworks, licensing systems, and enforcement capabilities in partner countries. It will also strengthen their capacity to prevent and detect the diversion or misuse of sensitive items at borders and transit points through training, technical assistance, and equipment provision. Furthermore, the Office will assist in securing international trade and disrupting networks involved in the proliferation of weapons of mass destruction and related materials. The legislation also mandates the Secretary of State, through this new Office, to develop and implement a comprehensive Export Controls and Border Security Strategy . This strategy will align and enhance United States foreign assistance in export controls to strengthen their effectiveness, reduce evasion risks, and promote secure global supply chains. Key elements include coordination across federal agencies, identification of priority regions, engagement with allies, and the use of artificial intelligence tools to enhance risk identification and customs enforcement. A report on this strategy is required to be submitted to Congress within 180 days of enactment, and the bill authorizes procedures for intra-departmental coordination of border security assistance programs across various State Department bureaus to minimize duplication and ensure efficient resource use.
