Taiwan's opposition blue-white alliance is firming up before the 2026 local elections, a boost for the KMT and TPP but a warning sign for the ruling DPP.

• Taipei mayor Chiang Wan-an registers for re-election on September 3 and will share a stage with TPP chairman Huang Kuo-chang on September 12, their first joint appearance.
• Li Si-chuan registers for the New Taipei mayor race on September 4, backed by outgoing mayor Hou Yu-ih.
• A blue-white split in Zhubei may be patched up, with talk of the TPP taking the city race and the KMT running for Hsinchu county chief, though both parties say nothing is final.
• The KMT publicly apologized after a budget cut left the presidential office unable to buy mooncakes from sheltered workshops, and pledged to cover the orders itself.
• Labor minister Hung Sun-han is set to attend an APEC meeting in Nanjing this month, which would make him the first minister-level official to visit China under President Lai.

Outlook: Expect more joint KMT-TPP appearances through September as both sides test whether cooperation holds in contested northern cities.
