Tensions inside Taiwan’s opposition Kuomintang are spilling into public view ahead of local elections, with Nikkei Asia reporting that U.S. and Chinese officials are tracking a split between party Chair Cheng Li-wun and figures aligned with Taichung Mayor Lu Shiow-yen.

What divides the party

The KMT-led legislative majority has repeatedly challenged President Lai Ching-te’s defense spending plans, drawing criticism from Washington and allied capitals. Nikkei said establishment figures aligned with Lu have taken stances that diverge from Cheng on how hard to resist Lai’s budget lines, complicating the party’s messaging on deterrence and cross-strait relations.

Academic observers quoted in Taiwan News warned that infighting is draining campaign energy. Local leaders focused on defending their own districts may not follow central party schedules, weakening coordinated attacks on the ruling Democratic Progressive Party.

External attention

Diplomatic sources told Nikkei that U.S. officials appear supportive of Lu, while Beijing remains invested in Cheng’s leadership and may try to undermine rivals. Cheng has publicly denied deep internal fractures, but a Washington-based analyst said tensions between her camp and Lu’s are real.

Foreign scrutiny intensifies when Taiwan approaches National Day and simultaneous U.S. congressional visits emphasizing arms cooperation. Opposition disarray can be misread overseas as instability in Taipei’s overall defense consensus.

Defense budget stakes

Legislators are debating next year’s defense budget amid uncertainty over U.S. support under President Donald Trump and persistent Chinese military pressure. Blocking or trimming Lai’s proposals without presenting alternative capabilities risks alienating voters who list security as a top concern in island-wide polls.

The KMT still shares a goal of performing well in local races, yet party headquarters has not produced a unified narrative on how much spending is enough—a gap the DPP is already exploiting in campaign ads.

Local election mechanics

City and county races hinge on bread-and-butter issues, but cross-strait tone sets the backdrop in Taichung, Taipei satellite cities, and southern counties with large military bases. Mayors who look softer on deterrence may energize one base while depressing another.

One KMT insider quoted by Taiwan News summed up the uncertainty: “No one knows what will happen after the local elections.” That quote captures the planning problem for candidates who need central party funds and legislative allies now.

What voters should watch

Track whether Cheng and Lu appear jointly at National Day events and whether the legislative caucus releases a single defense position paper before ballots drop. Fragmented signals suggest more gridlock in the spring session, regardless of who wins mayoral seats.
