On the same day, the Okinawa Prefectural Assembly passed a resolution calling for a review of the US-Japan Status of Forces Agreement. Whether Taiwan's nuclear power policy is about to make a major U-turn, and what's behind the internal power struggle within the KMT ahead of the election, we'll cover it all in a moment. ## Sponsor note: PremLogin Double Ten sale - **Dates**: Oct 10 to Oct 18, 2026 - **Offer**: buy 12 months of an eligible annual plan and get 1 month free (13 months total) - **Eligible**: Netflix, YouTube, Disney+, HBO Max, Amazon Prime, Spotify, Tidal, Canva Pro, Office 365, Duolingo, plus selected ChatGPT, Grok and Perplexity plans - **Not eligible**: standalone-account and top-up plans for ChatGPT, Grok and Perplexity, and Claude top-up plans - **New-customer code**: `markku666` (5% off the first order; whether it stacks with the sale is shown at checkout) - **Sale link**: (affiliate link) - **Full review and risks**: PremLogin is a third-party subscription-sharing platform.

US East Asia Envoy: Investors Are Overpricing Taiwan Strait Risk - **What happened**: Michael DeSombre, US Assistant Secretary of State overseeing East Asian and Pacific affairs, said investors are pricing the risk of a Taiwan Strait conflict too high, arguing that neither the US nor China wants conflict and both have the capability to deter the other. When asked about the so-called "2027 unification of Taiwan" narrative, he called Xi Jinping "a very rational actor," according to CNBC. - **Why it matters**: This is one of the most direct public statements yet from a US official on the Taiwan Strait risk premium, and it shapes how foreign investors view regional stability. That said, risk pricing is inherently subjective, and views differ widely. - **Taiwan's perspective**: Statements like this directly influence how foreign capital assesses Taiwan's stock market, the New Taiwan Dollar exchange rate, and supply chain de-risking decisions. - **Source**: CNBC () ### 2. Taiwan Considers Restarting Nuclear Power, Ma-anshan Could Resume Operations as Early as 2028 - **What happened**: Taiwan is considering abandoning its "nuclear-free homeland" policy and evaluating whether to restart the last reactor at the Ma-anshan Nuclear Power Plant, which was shut down in May last year. Power generation could resume as early as 2028, with another referendum scheduled for November to decide whether to abolish the nuclear-free policy. Currently, Taiwan's power mix is 47% LNG, 35% coal, and only 13% renewables, falling short of the 20% target set for 2025, while the government estimates electricity demand will keep growing by about 2.5% per year. Yeh Tsung-kuang, Dean of the Institute of Nuclear Engineering and Science at National Tsing Hua University, argues Taiwan needs a stable power supply going forward, while Yang Pei-wei, a researcher at the Taiwan Climate Action Network, believes that even restarting nuclear power would contribute only marginally to supply growth. - **Why it matters**: This marks a major pivot in Taiwan's energy policy, with direct implications for electricity costs and price stability for semiconductor manufacturing and AI data centers. The two experts disagree on how much restarting nuclear power would actually relieve supply pressure. - **Taiwan's perspective**: The outcome of the November referendum will directly determine Taiwan's power mix and electricity price trajectory for years to come. - **Source**: ABC News (Australia) () ### 3. KMT Shows Two Centers of Power Ahead of Election, Both US and China Watching Closely - **What happened**: According to Nikkei Asia, Taiwan's largest opposition party, the KMT, is experiencing internal tension just weeks before key local elections. Sources describe the party as having "two centers of power," with newly elected party chair Cheng Li-wun facing criticism from within the party. The report notes that this local election will set the tone for next year's presidential race, and both the US and China are closely tracking the KMT's internal dynamics. - **Why it matters**: Foreign media are treating Taiwan's local elections as a precursor to the 2028 presidential race and the direction of cross-strait policy. The KMT's internal factional struggle is being read by various parties as a barometer of Taiwanese public opinion, though there's no consensus yet within the party on which faction holds the mainstream view. - **Taiwan's perspective**: This local election is about more than choosing local executives; it will also be seen as an early signal of positioning on cross-strait and US policy. - **Source**: Nikkei Asia () ### 4. Okinawa Prefectural Assembly Passes Resolution Calling for Review of US-Japan Status of Forces Agreement - **What happened**: On October 9, Japan's Okinawa Prefectural Assembly passed a resolution by a vote of 45 to 2, calling for a review of the 1960 US-Japan Status of Forces Agreement. The move was triggered by the case of Devin Jacob Ballard, a 20-year-old US Marine lance corporal accused of killing 39-year-old Anna Yagi at a hotel in Naha and stealing her wallet; he denies the charges. The agreement has long been criticized for granting US military personnel near-immunity from Japanese domestic law, and Okinawa's assembly passed a similar resolution in 2024 following several sexual assault cases. - **Why it matters**: If the agreement is forced to be renegotiated, it would affect the legal flexibility of US forces operating within Japan. The Japanese government and the US Embassy have not yet issued a formal response to the resolution. - **Taiwan's perspective**: Okinawa hosts the US military's forward base closest to Taiwan within the First Island Chain. Any changes to the agreement would affect how freely US forces based in Japan could respond in a Taiwan Strait contingency. Okinawa is also a popular short-haul destination for Taiwanese tourists. - **Source**: France 24 () ### 5. Brazil's Supreme Court Issues Arrest Warrant for Bolsonaro's Son - **What happened**: On October 8, Brazilian Supreme Court Justice Alexandre de Moraes issued an arrest warrant for 42-year-old Eduardo Bolsonaro, ordering him to immediately begin serving a four-year prison sentence, revoking his passport, and instructing police to arrest him upon his return to the country. He currently resides in Texas, USA, holding a green card. In June, he was convicted of lobbying the US to interfere in the trial of his father, former president Jair Bolsonaro, including pushing for sanctions against Brazilian officials and tariffs on Brazilian exports. The warrant comes just weeks before the presidential runoff between incumbent President Lula and Bolsonaro's brother, Flavio Bolsonaro. - **Why it matters**: The timing of the arrest warrant, just weeks before the presidential runoff, could influence the election. How his family and supporters will respond remains to be seen. - **Taiwan's perspective**: Brazil is a key supplier in Taiwan's steel, soybean, and iron ore supply chains. Any political turmoil surrounding the runoff could affect commodity prices and Taiwanese business positioning in Latin America. - **Source**: Al Jazeera () ### 6. OpenAI Shuts Down Russian and Iranian "Fake Journalist" AI Propaganda Networks - **What happened**: On October 8, OpenAI announced it had shut down two influence operations, one linked to Russia and one to Iran, both using ChatGPT to create fake journalist personas that covertly spread anti-Ukraine propaganda and sought to deepen divisions in American and Israeli society over the Iran conflict. The Iranian operation created seven fake journalist profiles, each claiming to be from Western countries including the US. OpenAI identified roughly 100 articles published or syndicated under these pseudonyms, appearing across more than a dozen small and mid-sized online outlets worldwide. - **Why it matters**: This shows AI tools are already being used to manufacture seemingly authentic media identities at scale, posing a new challenge to global news credibility. OpenAI did not name the specific outlets affected. - **Taiwan's perspective**: This exact tactic, using AI to generate fake journalist submissions to real media outlets, is one of the forms of foreign information operations most frequently cited during Taiwanese elections. - **Source**: Euronews () ### 7. Hurricane Simon Could Strengthen to Category 4, Bearing Down on Mexico's Pacific Coast - **What happened**: As of early morning on October 9, Hurricane Simon had maximum sustained winds of 120 km/h, with its center located about 355 km south of Manzanillo, Mexico. Forecasters expect it to rapidly intensify into a Category 4 hurricane before landfall. US forecasting agencies have issued hurricane warnings for central and southwestern Mexico's coast, with hurricane-force winds expected within 36 hours. The area could see 20 to 38 cm of rainfall, with localized amounts reaching up to 63 cm, raising flood and landslide risks. - **Why it matters**: If the hurricane disrupts ports and overland transport along Mexico's Pacific coast, it would impact local logistics and public safety. The storm's path and intensity forecast remain subject to change. - **Taiwan's perspective**: Mexico's Pacific coast has become a key hub for Taiwanese manufacturers' "nearshoring" strategy for assembly and manufacturing serving the North American market. Port or transport disruptions could throw off delivery schedules for Taiwanese suppliers shipping to the US. - **Source**: CBC News () ## Closing The most important takeaway from today is that a US official has publicly said the market is overpricing Taiwan Strait risk, which makes for interesting context alongside Taiwan's own debate over the nuclear power referendum and the KMT's internal power struggle. Over the next few days, keep an eye on how the Japanese government and the US respond to Okinawa's resolution, as well as how the damage unfolds once Hurricane Simon makes landfall in Mexico. See you tomorrow. --- ## About this article and its author Originally published on [Mark Ku's Tech Notes](https://blog.markkulab.net/en/world-news/world-news-2026-10-09) License: [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) — when reusing or quoting, credit the author and link back to the original ### About the author **[Mark Ku](https://blog.markkulab.net/en/author/mark-ku)** — Software engineer - 10+ years as a software engineer - Built North-American e-commerce and AI SaaS subscription billing ### Free tools built by the author All of these are free to use: - [Free PDF Sign Tool](https://blog.markkulab.net/en/tools/pdf-sign): Online PDF sign tool — draw, type, or upload a signature, then drag, resize, and download.
