The prospect of a multibillion-dollar American arms infusion for Taiwan has rarely seemed closer, yet political crosswinds in both Washington and Taipei threaten to complicate the island’s defence modernisation. The US House Appropriations Committee has outlined $2 billion for Taiwan in its fiscal 2027 defence bill, half earmarked for the Taiwan Security Cooperation Initiative to enhance self-defence through training, medical support and co-development of uncrewed systems. This comes as Taiwan’s de facto ambassador to Washington expressed confidence that a separate, long-gestating $14 billion arms package would move forward under President Donald Trump, despite no formal decision. Viewed from Taipei, the dual-track funding signals a robust bipartisan commitment; however, the legislative package must still navigate the Senate and White House, where scepticism over foreign aid and the administration’s transactional instincts could pare it back.

Into this fluid landscape stepped Cheng Li-wun, chair of Taiwan’s opposition Kuomintang (KMT), on a carefully choreographed visit to Washington. Meeting Trump ally Senator Steve Daines and several House members, Cheng sought to reassure that her party “deeply values defence cooperation” and does not oppose American arms sales—a departure from the KMT’s historically ambivalent stance. Yet her trip was abruptly undercut when a scheduled meeting with National Security Council officials was cancelled at the last minute, after the venue had already been downgraded from the White House to a nearby office building. Taiwanese media framed the episode as a diplomatic brush-off; observers in European capitals detect an administration calibrating its engagement, perhaps wary of endorsing a party Beijing views as more pliable.

The domestic American backdrop further muddies the waters. The Trump administration’s efforts to confirm Todd Blanche as attorney general have hit Republican resistance, particularly over the now-officially-defunct $1.8 billion “anti-weaponisation” fund—a settlement-linked slush fund that acting officials insist is dead but which The Atlantic reports is still being quietly administered to benefit presidential allies. The fund’s controversy feeds into a broader narrative of erratic policymaking, making some lawmakers wary of long-term security pledges. From London, analysts note that the credibility of any White House commitment, including on Taiwan, must be discounted when key officials are fighting for survival and back-channel favours remain operational.

For Taipei, the dissonance is double-edged. The promised arms—ranging from missiles to joint unmanned systems—would significantly bolster asymmetric defences, but delays or a perception of American unreliability could prove as destabilising as any Chinese coercion. Meanwhile, Beijing, which views all US-Taiwan military ties as a violation of the One China principle, is likely to cite the KMT’s warm reception and the NSC snub as evidence that Washington itself is divided. The ultimate test will be whether the appropriations survive the political chaos and whether the arms package escapes the White House’s transactional calculus—factors that will shape cross-strait stability long after this week’s lobbyist carousel in Washington grinds to a halt.
