The package centers on PAC-3 and NASAMS missiles, with an additional $6 billion in asymmetric capabilities slated for a related package.

A large US arms package for Taiwan, including advanced air-defense interceptors, is prepared for approval by the president and could be announced after his China visit, with the package valued around $14 billion as the largest Taiwan arms deal yet.

Signatures can proceed even if budget reviews aren’t completed in time, with delivery schedules to be submitted to parliament once letters of offer and acceptance are signed.

Parliamentary opposition worries focus on the vagueness of spending measures, despite broad support for defense spending.

The authorization aims to prevent delays or cancellations and to avoid losing Taiwan’s place in the US arms production and delivery queue.

Taiwan’s parliament previously authorized signing four US arms agreements and, following a deadline risk, unanimously approved further authorization to sign four packages, tying into broader security strategy.

Defense officials say the deal demonstrates continued US commitment to Taiwan’s defense, even amid diplomatic sensitivities and shifting policy dynamics, and that signing should occur before spending reviews are finished to maintain delivery timelines.

Defense Ministry officials defend the process as rigorous and necessary to meet military requirements, arguing signing is needed to keep delivery timelines on track.

Opposition parties criticize the spending as lacking transparency, calling the proposals blank cheques.

Government measures face stall in the legislature due to opposition control, delaying authorization to sign contracts.

Lawmakers agreed to authorize signing the deals pending conclusions of a spending review, and separately to proceed ahead of the review to prioritize national security and timely access to hardware.

Parliament Speaker says the move upholds national security and territorial integrity, and calls for a full delivery schedule report for lawmakers after signing.
