On February 4, 1994, the United States lifted a nineteen-year trade embargo that had prohibited virtually all trade between the United States and Vietnam. Under this trade embargo, all U.S. citizens and businesses were barred from exporting or importing any goods from Vietnam. Moreover, such prohibitions extended beyond the United States to apply to any person or corporation subject to U.S. jurisdiction, including all foreign subsidiaries of U.S. firms and any other third parties. Although its strict regulations loosened in later years, the embargo was adamantly enforced until the day it was lifted.
