US space chief warns of emerging threats from China and Russia
Surging technologies spearheaded by Chinese and Russian forces represent the greatest threat in space defense, Chief of Space Operations Gen. B. Chance Saltzman said Thursday at the POLITICO Security Summit.
'The PRC has developed what we've kind of, you know, tongue in cheek, called a 'kill web,' and it's nothing more than a series of hundreds of satellites that are a sensor network that provide real-time updates, targeting quality information of our force,' Saltzman said, warning that the strategy represents the biggest threat in U.S. adversaries' growing space capabilities.
Saltzman emphasized the need to bolster U.S. capacity to disrupt the satellite network, saying it most acutely affects the Indo Pacific region.
But China's kill web isn't the only area of concern for the space chief. Saltzman also noted Beijing's 'accelerated ability to put capacity on orbit,' adding that Russia, another major U.S. adversary, is similarly demonstrating strength in that arena.
Russia, which is partnering with China to launch a joint lunar exploration project dubbed the International Lunar Research Station, also poses major threats to U.S. space defense, Saltzman said.
'The Russians are demonstrating reckless aggressive behaviors with regards to how they intend to contest the space domain that will have far-reaching impacts beyond any localized military effect,' Saltzman said, outlining three major areas of concern in Russian space technology development.
Russia's demonstrated kinetic kill capability, which saw it destroying a satellite and generating massive amounts of orbital debris in 2021 before launching its invasion into Ukraine; its cyber attack against Viasat the day it began its Ukrainian incursion and continued jamming efforts; and its ambition of putting a nuclear weapon on orbit all pose significant threats to security, the space chief said.
Saltzman's warnings come as the two U.S. adversaries ramp up their efforts to expand their space capabilities. Just last week, Beijing and the Kremlin signed a deal to build a joint nuclear power plant on the moon to power their planned International Lunar Research Station. The project aims to create a permanent base on the moon by the mid-2030s, in competition with the U.S.-led Artemis moon mission.

Ukraine-Russia Peace Talks Scheduled Amid Escalating Drone Strikes
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Ukraine will send a delegation to Istanbul for a new round of direct peace talks with Russia on Monday, President Volodymyr Zelensky announced Sunday, as the conflict rages on with deadly missile strikes and the largest drone assault of the three-year war. Ukrainian negotiators plan to present a roadmap for a long-term peace settlement during the upcoming talks in Istanbul, according to a document reviewed by Reuters. The proposal outlines an initial 30-day ceasefire as a first step, followed by the mutual return of prisoners and the repatriation of Ukrainian children taken to Russian-controlled territory. A meeting between Ukrainian President Volodymyr Zelenskyy and Russian President Vladimir Putin would follow. Newsweek has contacted the Russian Foreign Ministry and the office of President Zelensky for comment via email.

A Ukrainian security official, speaking to The Associated Press on condition of anonymity, said the drone strike targeted airfields including the Belaya air base in Irkutsk, located over 4,000 kilometers (2,500 miles) from Ukraine. It marks the first confirmed Ukrainian drone activity in the region. What To Know The official stated the long-range operation was planned over a period of 18 months and was personally overseen by President Zelensky. The drones, hidden in containers and transported by truck, reached their targets without being detected, according to Ukrainian sources. Tu-95 and Tu-22 strategic bombers—aircraft frequently used by Russia to launch long-range missile attacks on Ukraine—were among the targets hit, according to a source from Ukraine's domestic security agency, the SBU, who spoke to Reuters. The claim has not been independently verified. Igor Kobzev, the governor of Russia's Irkutsk region, confirmed a drone attack on a military unit near the village of Sredny in the Usolsky district but did not refer to any damage involving strategic aviation assets. Meanwhile, Russian forces launched a massive aerial assault on Ukraine over the weekend. Ukraine's air force reported the deployment of 472 drones—the largest single-day barrage since the start of the full-scale invasion in February 2022—alongside seven missiles. A missile strike on a Ukrainian army training facility killed at least 12 service members and wounded over 60, military officials said. Ukrainian drones are ready to be fired toward Russian positions in a shelter in Ukraine's Donetsk region on May 23, 2025.

Ukrainian authorities have ordered mandatory evacuations in 11 surrounding settlements as Moscow intensifies its push in the north. Ukrainian military officials also cited continued Russian offensives in the Donetsk region, particularly near Pokrovsk, Toretsk, and Lyman. As the military toll rises, President Zelenskyy confirmed that Defense Minister Rustem Umerov will lead the Ukrainian delegation to the Istanbul talks. What People Are Saying Zelenskyy said on Telegram: "We are doing everything to protect our independence, our state and our people." What Happens Next The talks will take place Monday. The Istanbul meetings represent a rare opportunity for diplomacy as the battlefield remains active on multiple fronts and the humanitarian toll continues to grow.

DeepSeek's lateset update is a serious threat to OpenAI and Google — here's why
Chinese AI startup DeepSeek is quickly gaining momentum in the global AI race. The company just released DeepSeek-R1-0528, proving once again that this is a bot to watch. The powerful update is already challenging rivals like OpenAI's GPT-4o and Google's Gemini. The new version delivers major performance gains in complex reasoning, coding and logic, which are areas where even top-tier models often stumble. With its open-source license and lightweight training demands, DeepSeek is proving to be faster and smarter. 🚀 DeepSeek-R1-0528 is here!🔹 Improved benchmark performance🔹 Enhanced front-end capabilities🔹 Reduced hallucinations🔹 Supports JSON output & function calling✅ Try it now: No change to API usage — docs here: 29, 2025 In recent benchmark tests, DeepSeek-R1-0528 achieved an 87.5% accuracy on the AIME 2025 test. This is a notable jump from the previous model's 70%. It also improved significantly on the LiveCodeBench coding benchmark, moving from 63.5% to 73.3%, and more than doubled its performance on the notoriously difficult 'Humanity's Last Exam,' rising from 8.5% to 17.7%. For those unfamiliar with what these benchmark tests mean, essentially, they suggest DeepSeek's model can keep pace with, and in some cases outperform, its Western rivals in specific domains. Unlike OpenAI and Google, which tend to guard their best models behind APIs and paywalls, DeepSeek is keeping things open. R1-0528 is available under the MIT License, giving developers the freedom to use, modify, and deploy the model however they like. Get instant access to breaking news, the hottest reviews, great deals and helpful tips. The update also adds support for JSON outputs and function calling, making it easier to build apps and tools that plug directly into the model. This open approach not only appeals to researchers and developers but also makes DeepSeek an increasingly attractive option for startups and companies seeking alternatives to closed platforms. One of the more impressive aspects of DeepSeek's rise is how efficiently it's building these models. According to the company, earlier versions were trained in just 55 days on roughly 2,000 GPUs at a cost of $5.58 million, just a fraction of what it typically costs to train models at this scale in the U.S. This focus on resource-efficient training is a key differentiator, especially as the cost and carbon footprint of large language models continue to draw scrutiny. DeepSeek's latest release is a sign of shifting dynamics in the AI world. With strong reasoning abilities, transparent licensing, and a faster development cycle, DeepSeek is positioning itself as a serious competitor to industry heavyweights. And as the global AI landscape becomes more multipolar, models like R1-0528 could play a major role in shaping not just what AI can do, but who gets to build it, control it and benefit from it.

Trump, Xi to talk this week about trade, key advisor says
President Trump and Chinese President Xi Jinping are likely to talk this week about the ongoing trade negotiations between the world's largest economies, National Economic Council director Kevin Hassett said Sunday, Why it matters: It would mark a major advance in the increasingly turbulent trade relationship between the countries, and is a step that U.S. officials have suggested was necessary for progress. Catch up quick: On Friday President Trump said on Truth Social that China had " totally violated" the tariff pause agreement the two countries reached in mid-May, raising fears the detente could be all but dead. Later that evening, he doubled steel tariffs. Between the lines: That pause deal with China contributed directly to a rebound in consumer confidence, CEO confidence and the stock market. What they're saying: "President Trump, we expect, is going to have a wonderful conversation about the trade negotiations this week with President Xi, that's our expectation," Hassett said on ABC's This Week. Hassett said nothing was firmly scheduled yet, but the expectation was the call would happen. The Chinese Embassy in Washington did not immediately respond to Axios' request for comment. Treasury Secretary Scott Bessent, in an interview on CBS's Face the Nation, would not go quite as far as Hassett, but he said "I believe we will see something very soon." The intrigue: Bessent said the Chinese were withholding exports for some products that were part of the May trade deal. "Maybe it's a glitch in the Chinese system, maybe it's intentional, we'll see after the president speaks with the party chairman," he said. Axios' Marc Caputo reported Saturday that a State Department plan to cancel Chinese students' visas was a reaction to China withholding exports of rare earth minerals crucial to high-tech manufacturing.
