Executive Director Yen Po-wen of the Tzu Chi Foundation revealed insider secret about procuring BioNTech vaccines, and whether the government acted to block civil groups from procuring vaccines has become a campaign focus among Taipei mayoral candidates. Kuomintang (KMT) candidate Chiang Wan-an criticized the government for blocking vaccines, favoring the local vaccine manufacturer Medigen, and disregarding human life. Independent candidate Huang Shan-shan also indicated that the government not importing vaccines was fatal and unforgivable, let alone its making money. Democratic Progressive Party (DPP) candidate Chen Shih-chung denied that he blocked vaccine purchases when he served as minister of health and welfare.

Taiwan is counting down to the local elections on November 26. The Taiwan World Press Association released a survey on the approval ratings of local government heads across 22 cities and counties.

September 15: More than half a year has elapsed since the major blackout on March 3 this year. The Taiwan Power Company announced a construction project to strengthen power grid resilience, with an expected spending of NT$564.5 billion (about US$18 billion). This is the highest amount for a single project in Taipower's history. Scholars believe that Taipower's announcement of the power grid improvement plan at this time may be an excuse for another big power outage in October.

The U.S. Senate Foreign Relations Committee passed the “Taiwan Policy Act” on September 14, 2022, authorizing US$6.5 billion foreign military financing and loan guarantee to Taiwan from 2023 to 2027 and designating Taiwan as a non-NATO ally.

Councilwoman Wang Hung-wei of Taipei stated that the NSB has become a bureau of instability. Legislator Chiu Cheng-yuan of the Taiwan People's Party (TPP) also stated that this is obviously a problem with the internal control of the NSB and called upon Chen to explain to the Foreign Affairs and National Defense Committee of the Legislative Yuan as soon as possible after the new legislative session opens.

The move drew criticism from members of Congress and former officials, who questioned that the administration of President Joe Biden would send the wrong signal to Beijing that the U.S. identifies its Taiwan policy as part of its China policy. In response to media inquiry, Deputy Spokesman Tsui Ching-lin of the Ministry of Foreign Affairs declined to comment, indicating that the change is an internal organizational matter of the U.S. government.

The shaking took place over an extended period, was felt across Taiwan, and involved dozens of aftershocks, causing the collapse of bridges and roads, landslide, and train derailment in the Hualien and Taitung area. A building collapsed in Yuli Township, Hualien, crushing the 7-Eleven convenience store next door. 
The badminton center on the fifth floor of the Taoyuan Bade Sports Center, far from the epicenter, had just been renovated and decorated, but the ceiling collapsed during the earthquake, and the people who were playing badminton fled. Mayor Cheng Wen-tsann apologized.
