Opening

Chinese Foreign Minister Wang Yi today demanded that Japan's former foreign minister "urgently correct" remarks concerning Taiwan, stating bluntly that China-Japan relations "have not yet normalized," as tensions flare up again. On the same day, the new Singapore plant of Vanguard International Semiconductor, a TSMC-backed venture, opened less than two years ago and is already running at full capacity thanks to AI-driven orders. Meanwhile, US stocks plunged more than 300 points as Treasury yields spiked, and we'll explain why in a moment.

Today's Global Spotlight

1. China-Japan Relations Stuck on Taiwan: Wang Yi Demands Japan "Urgently Correct" Course

• What happened: Chinese Foreign Minister Wang Yi met in Beijing on September 29 with former Japanese Foreign Minister Iwaya Takeshi, who led a delegation to China. The roughly 50-member business delegation, organized by the Japan Association for the Promotion of International Trade, is on a four-day visit. Wang Yi noted that China-Japan relations are in a severe situation and have not yet normalized. According to Nikkei Asia, he demanded that Japan "urgently correct its erroneous words and actions," a pointed reference to Prime Minister Takaichi Sanae's remarks in the Diet last November suggesting Japan would support the US in a Taiwan contingency.
• Why it matters: The Taiwan issue has become the biggest sticking point in China-Japan relations. Beijing has already imposed rare earth and tourism restrictions on Japan, and continued tension risks further disruption to critical raw material supplies.
• Taiwan angle: The China-Japan standoff over rare earths and components directly affects Taiwan's upstream electronics supply chain, which relies on Japanese materials.

2. TSMC-Backed New Singapore Plant "Fully Booked from Day One"

• What happened: Vanguard International Semiconductor (VIS), a TSMC-backed foundry, unveiled its first advanced wafer fab in Singapore on September 28. Built and completed in less than two years, the plant's capacity has already been fully booked due to surging AI infrastructure demand. The company is now evaluating construction of a second facility to expand its footprint.
• Why it matters: This shows the AI wave is straining not just leading-edge process capacity, but also mature and specialty node production.
• Taiwan angle: This marks the latest step in Taiwanese semiconductor makers' overseas diversification strategy, and it also affects the pace of order and talent migration away from Taiwan.

3. Jensen Huang and Zuckerberg Gather at the White House, Trump Calls Regulatory Concerns a "Hoax"

• What happened: Trump met with tech industry leaders at the White House on September 29, with attendees including Meta CEO Mark Zuckerberg, Anthropic CEO Dario Amodei, Google CEO Sundar Pichai, and Nvidia CEO Jensen Huang. House Speaker Mike Johnson said the meeting would address corporate responsibility for safety and the government's role. According to ABC News, Trump called safety concerns a "HOAX" and explicitly stated the US "rejects" global AI regulation.
• Why it matters: The White House's stance on AI regulation will directly affect the pace of Nvidia's product rollout and market strategy, and there's a clear divide between the tech industry and regulators over whether these concerns are genuine or just a "hoax."
• Taiwan angle: With Jensen Huang in attendance, whether US AI policy loosens or tightens affects Nvidia's order pipeline, which in turn impacts TSMC and Taiwan's AI server supply chain.

4. Treasury Yields Spike, Dow Plunges Over 300 Points in a Single Day

• What happened: US stocks fell broadly on September 28, with the Dow dropping 347.11 points (0.67%) to close at 51,481.51, while the S&P 500 and Nasdaq fell roughly 0.8% and over 0.9% respectively. The main driver was the 10-year Treasury yield hitting its highest level since 2007, with the 30-year yield reaching a high not seen since 2004, as markets worried about sticky inflation and increased bets on further Fed rate hikes. Boeing shares plunged nearly 7% after the FAA said it had not yet certified a software fix for the 737 Max 10.
• Why it matters: The yield spike reflects market concerns over inflation and the Fed's rate hike trajectory, and it's also affecting global capital costs and the dollar's trajectory.
• Taiwan angle: Rising expectations of Fed rate hikes tend to push the dollar higher and pressure the Taiwan dollar's exchange rate, while also influencing foreign investor flows into Taiwan's heavyweight tech stocks.

5. South Korea Attributes Injuries of 3 Soldiers to North Korean Landmine, Calls It a "Violation of the Armistice"

• What happened: On September 29, South Korea determined that an explosion in the Demilitarized Zone on September 21, which injured three South Korean soldiers (one of whom lost a foot), was most likely caused by a North Korean landmine. The Joint Chiefs of Staff based this assessment on the crater shape, the nature of the blast flash, and the severity of the injuries. According to Euronews, South Korean Defense Minister Ahn Gyu-back stated that "this is a clear violation of the armistice agreement, and North Korea must be held responsible."
• Why it matters: The risk of a flashpoint on the Korean Peninsula is rising, and South Korea has indicated it will take corresponding measures, with further developments likely to affect military deployments across Northeast Asia.
• Taiwan angle: Tensions on the Korean Peninsula affect military deployments across Northeast Asia, which in turn influences the positioning of US, Japanese, and South Korean forces around Taiwan.

6. Kyiv Hit by Intense Drone Attack, Interception Rate Only 57%

• What happened: Russian drones struck the Ukrainian National Academy of Sciences in central Kyiv on Monday, killing at least two people in one of the most intense drone assaults on the capital since the war began. Kyiv Mayor Vitali Klitschko said 24 people were injured and 6 hospitalized, with the strikes also hitting a pharmaceutical plant, a gas station, and medical facilities. President Zelensky said that of the 120 drones that attacked that day, 90 were jet-powered, and Ukraine's interception rate was only 57%.
• Why it matters: Jet-powered drones fly higher and faster, making air defense interception far more difficult, and this attack once again highlights the pressure on Ukraine's air defense systems.
• Taiwan angle: Real-world data on low-cost drone saturation attacks and interception rates offers a key reference for Taiwan's asymmetric warfare strategy and air defense procurement planning.

7. Tokyo Sees 34 Straight Days of Rain, Breaking a 140-Year Record

• What happened: Tokyo set a record of 34 consecutive days of rainfall on September 29, breaking the previous record of 33 days set from June 27 to July 29, 2019, the longest such streak since the Japan Meteorological Agency began keeping records in 1886. Cumulative rainfall in September had reached 629mm by Monday, approaching the monthly record of 670.9mm set in 1958. According to France 24, JMA meteorologist Kyota Masayuki said "this is partly linked to El Niño," adding that the autumn rain front has also lingered longer than usual this year.
• Why it matters: A JMA report indicates that global warming is having a long-term impact on Japan's weather patterns, including increased precipitation, suggesting this extended rainy spell may not be a one-off annual anomaly.
• Taiwan angle: Japan is Taiwan's top overseas travel destination, so prolonged rain combined with back-to-back typhoons will directly disrupt holiday travel plans and trip quality.

Closing

The most important takeaway today is that China-Japan relations are heating up again over the Taiwan issue, while surging Treasury yields are shaking up global capital flows, both storylines worth watching closely over the coming days. The North Korean landmine incident and Ukraine's air defense numbers are also a reminder that regional tensions have never truly cooled off. This is Mu Yan, see you again tomorrow at the same time.
