The Military Installation and Critical Infrastructure Protection Act of 2025 aims to bolster the security of agricultural land and critical infrastructure in Oklahoma by prohibiting foreign principals from adversary nations, specifically China, Russia, Iran, and North Korea, from owning or controlling such properties. The bill outlines definitions for key terms like "agricultural land," "critical infrastructure," and "foreign adversary," and establishes a framework for the sale, transfer, or divestiture of agricultural land owned by these foreign entities. It mandates that any foreign principal with ownership must divest within 180 days of the act's effective date and register with the Oklahoma Department of Agriculture, Food, and Forestry. Additionally, any contracts or agreements conflicting with this act will be deemed invalid, and the Attorney General is empowered to take legal action against non-compliant entities.

The legislation also includes provisions for whistleblower rewards, allowing individuals to report violations and receive 30% of the proceeds from any resulting land sales. It prohibits foreign principals from purchasing or controlling property within ten miles of military bases, with similar divestiture requirements. The act mandates that companies seeking access to critical infrastructure file a certification form and pay a fee, while ensuring that employees with access undergo background checks. Furthermore, it bans the use of software produced by federally banned corporations or foreign adversaries in state infrastructure. The Attorney General is responsible for overseeing compliance, notifying the Legislature and Governor about non-notified transactions, and establishing a process for reporting violations. The act is set to take effect on November 1, 2025.
