The Arms Export Control Act (AECA) is a U.S. law that regulates the export of defense articles and services. It aims to ensure that arms exports align with U.S. foreign policy and national security interests. The Act requires exporters to obtain licenses for the sale of military equipment and technology to foreign countries. Under the AECA, the U.S. government evaluates proposed arms sales to assess their impact on regional stability and human rights. The law also mandates reporting to Congress, allowing lawmakers to review and potentially block sales that may pose risks to U.S. interests or allies.
