The race for Keelung mayor has officially begun, with the DPP camp drawing on former President Tsai Ing-wen's popularity to build momentum for Tung Tzu-wei — a positive signal for the ruling party's prospects in northern Taiwan.

• Tung Tzu-wei completed his registration as a candidate for Keelung mayor, with Tsai Ing-wen accompanying him in person and serving as chair of his campaign headquarters.
• The campaign is centred on continuing past achievements: over the past eight years, Keelung's east bank port area was opened up, the naval port was relocated westward, and the city and harbour were regenerated; the next step is to "light up the west bank."
• Tsai Ing-wen is also serving as campaign headquarters chair for Taitung County magistrate candidate Chen Ying and New Taipei mayoral candidate Su Chiao-hui, indicating that she is playing a central role in campaigning during this election cycle.
• Tung Tzu-wei stressed that cooperation between central and local government is key, pledging to work with the central team of Lai Ching-te and Cho Jung-tai to advance Keelung's development.

Outlook: The central theme of the race will revolve around "whether central-local cooperation can continue," with development of Keelung's west bank becoming a focal point of contention between the KMT and DPP.
