This bill, known as the PORCUPINE Act, amends the Arms Export Control Act to include Taiwan among the nations eligible for shorter certification and reporting periods for defense articles and services. These changes streamline processes for arms sales and military assistance, placing Taiwan alongside close allies like New Zealand and Israel for expedited transfers of defense capabilities. The legislation also mandates a feasibility assessment by the Secretary of State for establishing an expedited decision-making process for third-party transfers of military equipment to Taiwan. This assessment, due within 90 days, would cover transfers from key allies such as NATO members, Japan, Australia, South Korea, New Zealand, and Israel. It specifically explores requiring licensing applications for government-to-government agreements to be processed within 15 days, and other requests within 30 days. Additionally, the bill requires biennial reports on the amendments' effectiveness and includes a rule of construction affirming that it does not alter existing U.S. policy toward Taiwan. The Act is designed to sunset seven years after its enactment.
