Geopolitics Daily Brief — July 31, 2026

What matters this morning

1. U.S.-China technology: Chinese military-linked researchers used U.S. AI outputs in local systems

• Reuters reviewed more than 80 Chinese academic papers and patents and found that researchers linked to the People’s Liberation Army and other military institutions used outputs from OpenAI and Anthropic models to develop domestic systems. 2
• The papers describe model distillation: using a larger model’s outputs to train smaller systems that can run locally with less computing power. One PLA-linked study used GPT-3.5 summaries of sensitive military source code; other studies examined UAV image processing and target recognition. 2
• Reuters said the reporting did not establish broad operational deployment or a measurable commercial loss. China’s foreign ministry, the PLA, the Pentagon, the White House and the companies named did not respond to requests for comment. 2

2. Russia-Ukraine: Drone attack sets Volgograd energy facility and logistics hubs on fire

• Volgograd’s regional governor said a drone attack set an energy facility and warehouses ablaze on Friday and injured five people; he did not identify the facilities. 4
• Online retailer Wildberries said one of its logistics hubs in Volgograd caught fire, while Reuters noted that the region is home to a Lukoil oil refinery. 4
• Reuters reported that Ukraine has recently intensified attacks on Wildberries facilities and energy sites; Kyiv describes its deep strikes as a way to reduce Russia’s war-fighting capacity, while Moscow has not publicly accepted responsibility for any comparable claim in this report. 4

3. Middle East: Bab el-Mandeb remains passable while Hormuz traffic is nearly frozen

• Kpler data counted 25 commodity vessels through Bab el-Mandeb on Thursday: 18 entered and seven exited, including two very large crude carriers, one Suezmax and five Aframax tankers. 1
• Only two vessels transited Hormuz, both entering in ballast, according to the same data. Ships with transponders switched off are not included in the count. 1
• Reuters said a drone strike on gas vessels at Egypt’s Damietta port raised the possibility of pressure on navigation near the Suez Canal, but the report did not establish a canal closure or a quantified loss of oil and LNG supply. 1

4. Taiwan Strait: China’s coast guard patrols east of Taiwan

• China said a coast-guard patrol led by the ship Xiushan was conducting routine law enforcement east of Taiwan and would strengthen control over the relevant waters. 5
• Taiwan said it detected the Xiushan and Chongming; one was about 151 nautical miles east of Lanyu, also known as Orchid Island, and the other about 43 nautical miles to the island’s northeast. 5
• Taiwan sent its patrol ship Taipei to monitor the Chinese vessels and called the operation a political expansion of power. Reuters said Taiwan considers the eastern waters important for wartime supply lines from allies. 5

5. U.S.-China trade: Washington presses Beijing on rare-earth and farm-product commitments

• Treasury Secretary Scott Bessent said he and U.S. Trade Representative Jamieson Greer told Chinese Vice Premier He Lifeng that Washington expected Beijing to honor commitments on rare earths and agricultural products. 3
• The officials discussed using bilateral Trade and Investment Boards to pursue progress, ahead of a possible September meeting between President Donald Trump and President Xi Jinping. 3
• Reuters reported that Washington views China’s recent commercial decrees and export restrictions as problematic; Xinhua said Beijing had raised serious concerns about recent U.S. trade restrictions. 3

Watchpoints

• Whether the reported AI-model use produces a new U.S. rule aimed at model access, output extraction or Chinese military-linked customers.
• Whether the Volgograd fire affects Lukoil refining, Wildberries distribution or Russian fuel availability beyond the local area.
• Whether Hormuz records more loaded tanker movements, and whether any new incident affects Damietta or Suez traffic.
• Whether China’s east-of-Taiwan patrol becomes a repeated coast-guard presence or is coordinated with PLA exercises.
• Whether Beijing provides measurable rare-earth or farm-product deliveries before the possible September Trump-Xi meeting.
