China is helping Russia build a faster Shahed. Russia has begun using upgraded Shahed drones with Chinese-made turbojet engines that fly at speeds close to three times those of earlier versions, the Wall Street Journal reported.

The Shahed jet is designed to beat Ukraine's air defenses. Ukrainian interceptors have downed about 90 percent of the older piston-engine drones, which cruise at roughly 180 kilometers per hour, so Russia switched to the jet-powered Geran-4, which cruises at around 500 kilometers per hour.

The engines come from one Shenzhen firm

The turbojets come from Telefly Telecommunications Equipment, founded in Shenzhen in 2010. The company chiefly makes computer hardware and communications equipment, but also sells its own line of micro-turbojets for drones.

China has long been the main clearinghouse for Shahed parts, including engine components, servomotors, and gyroscopes, the newspaper reported.

The company scrubbed its own website

After Ukraine publicized the discovery of Telefly engines in Russian drones, the turbojet section disappeared from the English-language pages of the company's website. The pages in Chinese and other languages still carry them.

China's foreign ministry, which did not respond either, has previously said it strictly regulates exports of dual-use components and rejects unilateral US sanctions on such trade.

Western parts fade as Chinese parts arrive

Downed Shaheds once carried microcontrollers from Texas Instruments in the US and linear regulators from STMicroelectronics, which the newspaper lists as being based in Switzerland. Over time, the Western components are disappearing even as the drones gain better navigation and attack systems, because US Treasury investigations found nearly all the Western parts were being diverted through Chinese intermediaries, often shell companies in Hong Kong.

Ukrainian government researcher Colonel Oleksandr Zaruba said in June that Shaheds now hold more antennas, modems, and SIM cards to correct their flight paths through local mobile networks, and that the components increasingly come from China.

A Chinese national studying in Canada allegedly crossed over into the United States earlier this year to take photos of facilities near the Chicago airport at the direction of a suspected Chinese government official, according to newly filed court records. The Chinese official repeatedly told the student to destroy the SIM cards they used to communicate and stick to a Huawei phone.

The records provide insight into how Chinese state actors continue to use students to essentially crowd source imagery of sensitive U.S. locations or military aircraft, and how those students are told to remain undetected.

Seamus Hughes of Court Watch first identified and posted the records on Wednesday. 

Weiheng Zeng is an undergraduate student at the University of Waterloo, Ontario, Canada and has crossed into the U.S. around two dozen times since 2022, according to an affidavit from an FBI Special Agent. 

In April, an unknown person was seen inside the FedEx employee parking lot at O’Hare International Airport in Chicago, Illinois, the document continues. This person looked like they were taking photos of aircraft or other parts of the airport. They climbed onto a forklift to take photos in the direction of the aircraft, and tried to get into a FedEx truck, according to photos included in the document. Authorities later figured out this was Zeng based on the dark blue Chrysler Town & Country vehicle that left the area and that he was connected to

When Zeng tried to enter the U.S. again last Sunday, Customs and Border Protection (CBP) interviewed him repeatedly. At first, Zeng said he planned to travel with his sister and a classmate. CBP agents then reviewed his phone and found multiple photos of aircraft, the document says. Zeng told the agents “he takes pictures of model aircraft being tracked for a flight radar website,” it adds. At one point he said he takes the photos as his hobby. Agents also found photos of Zeng and others in tactical clothing holding rifle-styled firearms. Zeng said this was an airsoft gun.

Zeng changed his story repeatedly, before revealing taking the photos was more than a hobby. Instead, he knows someone referred to in the court record as his “Chinese Contact.” This contact assigned Zeng specific planes and their tail numbers to photograph, and then paid Zeng $20 to $30 per picture. Zeng said this Chinese Contact sent him SIM cards to communicate, and then told him to destroy the cards, their chats, and delete the photos he took. Later Zeng said the contact told him to use his Huawei phone to communicate, and never take that phone into the U.S. 

Zeng claimed the Chinese Contact approached him through “an aviation spotter website” around a year and a half ago, the document continues. Zeng said he believed this person was connected to the Chinese Communist Party, and later told the FBI the person sent a photo of an official looking badge. The language the contact used “was very organized and managed, not language typically used between friends,” the document adds. When the FBI later looked into this site, the agency found it appeared to not exist, according to the court record.

One of the photographed planes was an American United aircraft which had “a unique, temporary paint job, of which photographs were highly desired,” according to Zeng. The contact wanted Zeng to go to places in Orlando, Las Vegas, and Los Angeles to take photographs of specific locations around airports, the document says. Zeng said he denied these requests and accepted two tasks over 18 months. One of those was to get the photos of the interior of the FedEx facility at O’Hare International Airport. In all, he made $500, the document says.

“ZENG stated ‘Chinese Contact’ was not satisfied with the photographs and the photographs were fine, but not what were ‘expected’,” the document adds.

There has been a 76% increase in under-construction gas-fired projects amid ‘frenzy’ to build more datacenters

The US has surged ahead of China in the building of new gas-fired power generation, largely to feed a boom in artificial intelligence (AI) that is adding vast amounts of planet-heating emissions, a new analysis has found.

For decades, China’s rapid economic growth has seen it outpace the US in the addition of new gas power generation but a recent “frenzy” in datacenter construction for AI has reversed this, said Global Energy Monitor (Gem) in its new report.

Ukraine celebrated 35 years of independence on 24 August, and Ukrainian President Volodymyr Zelenskyy marked the day with an address listing what the invasion has cost Russia, published by the President's Office. He said Putin is mortal and out of time to understand Ukraine, and said Ukraine will not hand over Donbas or save the Kremlin half a million soldiers. He also asked partners for sanctions and weapons strong enough to force an end to the war.

Russia has been invading Ukraine since 2014 and fighting a full-scale war on it since 2022, and Ukraine now supplies a growing share of the missiles and drones it fights back with, while the air defense shielding its cities still hangs on decisions taken in Washington and European capitals—which is what makes a holiday speech a statement of what Kyiv will not trade and what it needs built or delivered next.

The losses he read back to Moscow

President Zelenskyy turned from his own citizens to Russia partway through the speech. 

"You wanted to take all our Ukraine, all our land; instead, you lost your oil refineries, your fleet, your profits, your entire generation that you sent into the meat grinder," he said. 

A country that wanted Ukraine erased from the map, he added, is now absent from the international agenda of the future civilization.

He set Moscow's self-image against its filling stations. 

"For 27 years, the head of Russia has talked about greatness, while Russia is standing in lines for gasoline," Zelenskyy said. 

Moscow and St. Petersburg brought back gasoline rationing this month, and Rosneft capped fills at every station in the country.

On the Russian leader he was blunt. 

"Putin hopes that we are tired. But we know that he is mortal," he said, adding that Putin never understood Ukraine and now will not have the time to.

A fifth Independence Day at war

Before the holiday, Russian ballistic missiles hit Kyiv and its main airport hub twice in 24 hours. A solution to Russian ballistic terror must be found, Zelenskyy said, and that gamble must not pay off. 

Russia does not want peace, it wants mobilization, the president said. Ukraine will not let Moscow seize the initiative or convince Europe that surrendering Donbas ends the war. Russia keeps pushing back the dates for taking all of Donetsk Oblast and will keep pushing them back, he said.

The president called Ukraine's defense industry a giant that forges independence around the clock, and demanded more from it. Mid-range strikes cut Russian logistics and long-range weapons cut Russian profits, he said, listing Moscow, Tuapse, Tula, Ryazan, Olenya, and Omsk among the places already hit.

Ukraine's home-built Flamingo cruise missiles should stop being a rare species and arrive en masse: "They must 'winter' in Russia," Zelenskyy noted. 

Previously, Flamingos have hit defense plants more than 1,000 km from the border, though they still appear in strikes in small numbers.

"China should no longer remain silent"

Ukraine is not asking anyone to fight for it, the president said — only for everything needed to stop the war before Putin starts the next one. He wants sanctions that make Russians howl and Moscow at a negotiating table, and said Washington has lost its illusions about Russian intentions. Europe must be Europe, he said: united, ambitious, brave. 

"China should no longer remain silent," he added, saying Beijing must cool the ardor of someone who puts on a sailor's uniform and cap and talks about a nuclear strike—a description that fits Putin.

I understand the pressure on AI companies to rush forward. But employees are right to be concerned

Last month, more than a thousand employees at frontier AI companies signed a letter asking the US government to find a way to “pace” AI development, citing the risk of the technology spiraling out of human control as it begins to build itself.

They were right to be concerned: just days earlier, two AI models that OpenAI was testing internally escaped the test environment, then autonomously hacked the company Hugging Face and at least three other online services. A few days after that, Anthropic announced that some of their models had also broken out and hacked other companies during testing.

A weak yuan guarantees Beijing massive trade surplus even as the White House tries tamp down on Chinese imports

Since China offered a truce in the trade war last October following its threat to deprive the United States of rare-earth magnets, the Trump administration has been happy to stop escalating. After all, imports from China have been falling, down by 40% in the year to June, compared with the same period in 2024. Best to declare victory and call it a day.

But the US hasn’t won this battle – and there’s strong evidence to show it’s too chicken to really try.

Despite the recent hearings in Congress, we seem to be even further from the goal of understanding Covid-19’s origin’s than we have ever been

As a microbiologist and infectious disease clinician, it has been tough to watch the recent devolution of public discourse on Covid-19 origins. It has been especially difficult for me to read the comments of Anthony Fauci about the origins debate in his now-public diary. And it has been painful to watch the televised spectacle hosted by the US senator Rand Paul on 29 July involving a hostile interrogation of Fauci.

Despite many early pleas, including my own, for a dispassionate, objective assessment of what we know, don’t know and need to know about Covid-19 origins, we seem to be even further from this goal now than we have ever been – plagued by politicization, polarization and illogical thinking.

Russia has ceased producing its Geran-3 jet-powered attack drone, Ukraine’s Military Intelligence (HUR) told the Ukrainian defense outlet Militarnyi. The agency estimates Russian industry now makes about 3,000 newer Geran-4 and Geran-5 drones per month.

Russia is shifting toward faster jet drones as Ukraine’s low-cost interceptors have become more effective against slower Shaheds. The Geran-4 and Geran-5 leave defenders less time to react, requiring faster interceptors or short-range air defenses. At the reported production rate, these newer Geran models, previously used in limited numbers, could become a regular feature of Russian attacks.

HUR said Russia has established serial assembly of the two newer models at the Alabuga complex in Tatarstan, with other Russian companies supplying components. The agency also said Russia’s Defense Ministry wants to expand Alabuga’s capacity. Construction began in May. Satellite imagery showed large-scale work by early July 2026, although the purpose of the new buildings remains unknown.

From Geran-3 to newer jet drones

Russia first used Geran-3 drones in large numbers during a combined nighttime attack on Ukraine on 30 July 2025. At least eight flew alongside propeller-driven Shaheds and decoys. The model retained the Geran-2 airframe but replaced its piston engine with a Chinese Telefly JT80 turbojet. HUR gave it a speed of 300–370 kilometers per hour and a range of up to 1,000 kilometers.

In May, then-Defense Ministry adviser Serhii “Flash” Beskrestnov said Ukrainian defenses stopped 95% of incoming Shaheds during the most recent documented strike and predicted Moscow would produce more jet-powered Geran variants.

The newer Geran-4 has a more robust airframe than the Geran-3 and is designed for high-speed flight and maneuvers. It can reach 500 kilometers per hour.

The larger Geran-5 carries a roughly 90-kilogram warhead and has a stated range of up to 1,000 kilometers. HUR has said Russia may equip it with R-73 air-to-air missiles, potentially threatening aircraft sent to intercept it.

The Chinese engines that Russia itself can't build

The Geran line combines Iranian designs, Russian assembly, and imported technology. HUR described the Geran-3 as a localized version of Iran’s Shahed-238. It found 45 foreign components inside, including parts from the United States, China, Switzerland, Germany, Britain, and Japan.

Russia depends on China for the turbojet engines in newer Geran models. HUR deputy chief Vadym Skibitskyi told RBC-Ukraine that Russia remains fully dependent on Chinese turbojet engines for the Geran-4 and Geran-5. Each costs about $35,000–$40,000, he said.

A Chinese XK-F358 mesh radio recovered from a Geran-5 also helps Russian drones resist jamming. Its manufacturer remains outside the US, EU, UK, and Ukrainian sanctions, according to a review by Euromaidan Press.

The radio that makes Russia's strike drones resistant to Ukrainian jamming is a Chinese-made part sold openly, and the company that makes it has escaped the sanctions hitting the rest of the drone supply chain, the OSINT group Frontelligence Insight found. The part, a mesh radio modem, has been pulled from downed Russian drones even as Western and Ukrainian sanctions expanded to cover the engines, navigation, motors, cameras, and chips around it.

Russia's war on Ukraine now runs on drones built largely from Chinese parts—a flow China keeps open to Moscow while restricting the same goods to Kyiv.

The part that isn't on any list

The modem is the XK-F358 mesh radio made by Shenzhen Xingkai Technology Co., Ltd. of Guangdong. It sells openly online. The company's Made-in-China storefront lists it at $8,100 to $9,000 apiece, and Serhii "Flash" Beskrestnov previously put the price near $7,000.

Ukraine and its partners have sanctioned Chinese suppliers of drone engines, navigation receivers, motors, cameras, and chips—one Ukrainian round aimed explicitly at parts for drones built to bypass electronic warfare—but not the radios.

Recovered from downed drones, and hard to jam

Ukraine's Defense Intelligence photographed an XK-F358 recovered from a downed Geran-5, and Beskrestnov photographed another taken from a Gerbera, Militarnyi reported on 19 January 2026.

The modem uses COFDM modulation and a mesh design in which each unit relays traffic for the rest, so packets reroute automatically when a node drops.

The same modem also turns up under a second name—HX-50, in a more industrial variant—and its use is no experiment: it spread onto Russia's Shahed-136/Geran-2 strike drones from July 2025 and reached serial integration by early September.

The network keeps working after losing roughly 80% of its nodes and can link drones across more than 100 kilometers, or up to 600 in relay chains, according to Beskrestnov, a Ukrainian defense adviser who has examined the recovered units. That is why conventional jamming struggles against it: an attacker has to suppress every node at once rather than break a single link.

What sanctions cover, and what they skip

Ukraine's National Security and Defense Council (NSDC) has sanctioned Chinese makers of navigation receivers, motors, cameras, and chips. The US Treasury designated Xiamen Limbach and Redlepus in October 2024, the EU added Shenzhen Minghuaxin in June 2026. No maker of radio or data-link modems appears among them.

None of the four sanctions regimes that have pursued Russia's Chinese drone suppliers—the US, EU, UK, and Ukraine—lists Shenzhen Xingkai, a direct check of each register by Euromaidan Press confirms.

The gap cuts both ways. Ukrainian battalion commanders and industry sources put the share of parts in a standard Ukrainian FPV drone—batteries, motor magnets, fiber-optic cable—at up to 65% Chinese-made, and Ukraine buys from Shenzhen too.

Cutting one supplier, then the next

Tatarigami, who founded Frontelligence Insight, argues the fix is to extend controls beyond individual firms to the entire chain—down to the optical fiber, the reels it ships on, and the machines that make it. Fiber-optic drones already make up about 60% of Russian FPVs in key sectors, Euromaidan Press reports. The record on firm-by-firm designation is discouraging: after Washington hit Xiamen Limbach, Beijing Xichao took over the engine shipments, Reuters found, and Kupol's Garpiya order climbed from 2,000 drones in 2024 to more than 6,000 this year. But among all component categories in a Geran drone, the one that enables jam-resistant control is the only one absent from the registers.

What controls can reach, and what they can't

Xingkai also markets the modem for civilian work—mining, firefighting, maritime. And as the Xichao case shows, cutting off one company rarely halts the flow.

China's foreign ministry claims it knew nothing of the parts exports, says it controls dual-use goods under its own law, and rejects sanctions it calls baseless.

The harder problem is that the same civilian electronics feeding Russia also stock Ukraine's drone lines, so any workable control has to reach named military buyers without severing the dual-use trade Kyiv still needs. And sanctions may not decide this contest at all: Ukraine is already testing electronic-warfare methods built to break the very mesh networks these radios create.
