The US has delivered Taiwan’s first two newly built F-16 fighter jets, part of an $8 billion order that has repeatedly drawn condemnation from Beijing.

The two aircraft, the modern F-16V Block 70 variant, arrived in Taiwan on Friday. They are the first of 66 new fighters approved for sale by Washington in 2019.

Beijing has long opposed US arms sales to Taiwan, which it considers part of China. The delivery came a week after Chinese President Xi Jinping visited Washington and urged US President Donald Trump to oppose “Taiwan independence” and “handle the Taiwan question with caution.”

The new jets will join Taiwan’s existing fleet of older F-16 variants, which Taipei has operated since the late 1990s. The first aircraft from the 66-plane order were initially expected in 2023, but deliveries were delayed by software development and production issues.

China’s Defense Ministry warned Washington in August to “stop arming Taiwan in whatever form” when asked about the expected delivery.

The US maintains a one-China policy but remains Taiwan’s primary foreign arms supplier.

Under the Trump administration, Washington has approved its largest military packages for Taiwan to date, greenlighting an unprecedented $11 billion in arms last December. Trump has also stalled an even larger $14 billion military package for months, openly describing the sale as a “very good negotiating chip” in talks with Beijing.

Taiwan has remained de facto self-governing since 1949, when nationalist Kuomintang forces retreated to the island after losing to the communists in the Chinese Civil War.

Beijing regards Taiwan as part of its territory under the One China principle, a position recognized in varying formulations by most UN member states, including Russia. China has said it prefers peaceful reunification but has not ruled out the use of force.
