The US carmaker will 'adhere to visual processing solutions' to achieve safer intelligent driving in various scenarios, the company said in a post on Chinese microblogging platform
Weibo on Sunday.
It added that this initiative would prove that 'advanced technology doesn't require expensive, complicated sensors'.
The post formed part of Tesla's latest
social-media campaign on the mainland, which reasserts billionaire chief executive
Elon Musk 's scepticism of lidar – short for light detection and ranging. Similar to radar, lidar uses lasers to measure a car's distance from objects, providing higher precision in certain environments.
Musk in 2019 famously dismissed the idea of installing lidar sensors on EVs, calling it a 'a fool's errand' because of the high production costs involved.

On the mainland, however,
one out of every four new cars taking to the streets this year is expected to be fitted with at least one lidar sensor, according to a recent China Securities report.

China cracks a code on invisible battlefield surveillance
This month, the South China Morning Post (SCMP) reported that Chinese radar scientists have demonstrated a breakthrough system enabling aircraft to detect moving ground targets with high clarity while remaining completely radio-silent. Led by Li Zhongyu of the University of Electronic Science and Technology of China, the team used two Cessna 208 planes in formation, with one actively transmitting radar signals and the other passively receiving echoes, to test their 'space-time decoupling two-channel clutter cancellation method.' As reported in the Journal of Radars, the test tracked three vehicles across terrain previously inaccessible to traditional radar due to clutter, range migration and Doppler noise. Through advanced motion correction, spectrum compression and a novel matrix-based clutter suppression technique, the system isolated targets with over 20 decibels more clarity than current technologies. The passive aircraft never transmitted signals, making it nearly impossible to detect or jam, ideal for low-probability-of-intercept (LPI) missions, according to the Journal of Radars report. Instead of relying on artificial intelligence, the method utilizes efficient mathematical models specifically designed for real-world applications. The development could allow Chinese aircraft and missiles to silently scan battlefields, oceans or skies, identifying mobile threats without alerting adversaries. Li called the system a world first, positioning China at the cutting edge of stealth radar capabilities amid growing global electronic warfare competition. Explaining the complementary nature of passive and active radars, Eric Hundman mentions in a March 2025 report for the China Aerospace Studies Institute (CASI) that passive radars can often detect stealth aircraft, as they're hard for anti-radiation weapons to target because they emit no signals. However, Hundman says the applications of passive radar remain relatively limited due to its reliance on unpredictable external signals, narrow usable frequencies and relatively unsophisticated processing algorithms. As for active radars, Hundman says they offer high-resolution, multi-function capabilities, combining stealth detection, surveillance, tracking and fire control in increasingly mobile and networked platforms. However, he points out that since active radars emit signals, they are vulnerable to detection by passive sensors and anti-radiation missiles. In view of each system's limitations, Hundman states that Chinese researchers are working to complement active radars with passive systems and pursue network integration, aiming to fuse data across platforms for a more resilient and comprehensive radar network capable of withstanding electronic and kinetic threats. Discussing the potential operational application of the technology, the US Department of Defense's (DOD) 2024 China Military Power Report (CMPR) states that the People's Liberation Army (PLA) continues to make progress in the development and integration of unmanned systems, including drone swarm tactics and manned-unmanned teaming (MUM-T) concepts. According to the report, these efforts include employing drones for intelligence, surveillance and reconnaissance (ISR), as well as electronic warfare, decoys and potentially precision strike missions in coordination with stealth aircraft. In an April 2025 report for the Center for Strategic and Budgetary Assessments (CSBA), Travis Sharp highlights the strategic pairing of manned stealth fighters and collaborative combat aircraft (CCAs), emphasizing their complementary roles in air dominance. Sharp says CCAs, acting as loyal wingmen, would use active radar to detect and track enemy aircraft, transmitting targeting data to stealth fighters that remain electronically silent to avoid detection. He notes that this setup enhances survivability while extending the fighter's engagement range, allowing long-range missile strikes before the enemy is aware. Sharp adds that CCAs can also jam enemy radars, further complicating adversary targeting efforts. He points out that such tactics are key to improving loss-exchange ratios in potential conflicts, including in the Taiwan Strait between the US and China. The advent of China's purportedly sixth-generation fighters adds impetus to the development of such technology. Malcolm Davis mentions in an SCMP article this month that China's J-36, which appears to be optimized for air-to-air combat with very long-range missiles, could achieve advanced stealth and teaming with collaborative combat aircraft (CCA). Further, Timothy Heath mentions in the same article that sixth-generation fighters are unlikely to be involved in maneuvering dogfights but instead focus on command and control, enabling unmanned aircraft to conduct strikes against air, marine and ground targets. Ditching manned fighters altogether, the SCMP reported in May 2025 that China's Jiu Tan drone carrier, a super-high-altitude, long-range unmanned aerial vehicle (UAV), could carry up to 100 kamikaze drones or six tons of ammunition with a maximum range of 7,000 kilometers and an altitude of 15,000 meters. SCMP notes that, if deployed, the Jiu Tan could contribute to the PLA's swarming capabilities, wherein large groups of drones are released to overwhelm an adversary's defenses. Stacie Pettyjohn and other writers mention in a June 2024 report for the Center for a New American Security (CNAS) that China could utilize its diverse drone fleet, ranging from kamikaze to reconnaissance and loyal wingman-type systems, to saturate air defenses, rapidly close kill chains, and complicate Taiwan and US countermeasures in a conflict over the island. Pettyjohn and others say that China holds an initial advantage due to its large, inexpensive and varied drone arsenal, which could be used to locate and strike US and Taiwanese forces with speed and scale. They also warn that drone mass and rapid adaptation, not just innovation, is critical, citing Ukraine as a cautionary example, with China's production capacity giving it a dangerous edge in the opening phases of a Taiwan war. As for the US's capability to counter drone swarms, Wilson Beaver and Ka'Von Johnson mention in a Heritage Foundation report this month that the US faces growing challenges in countering drone swarms due to fragmented capabilities, underdeveloped training and an overreliance on costly systems. Beaver and Johnson say that while kinetic interceptors and electronic warfare tools offer layered defenses, gaps persist in small-drone detection, real-time threat identification and swarm neutralization. They point out that directed-energy weapons, such as lasers and high-powered microwaves (HPMs), remain impractical due to issues with range, power and target discrimination. In addition, they say most counter-drone systems are not widely fielded, few troops are trained to operate them and base commanders often lack the authority to engage drones, compounding vulnerabilities. While the US races to patch gaps in drone defenses, China is methodically assembling a sensor-strike network designed to operate silently, resiliently and at scale.

Apple's most sweeping software redesign disappoints mainland Chinese consumers
Apple on Monday previewed a new software interface design, called Liquid Glass , during the company's annual Worldwide Developers Conference held at its US headquarters in Cupertino, California. For the very first time, the new design extends across Apple's different operating systems – iOS 26, iPadOS 26, macOS Tahoe 26, watchOS 26 and tvOS 26 – which have been rebranded to mark the coming year, rather than a version number. Chinese consumers, however, expressed their disappointment with the new design, as the hashtag 'iOS26 Ugly' became the top-trending topic on Chinese microblogging app Weibo on Tuesday. The platform saw more than 20,000 mainland netizens express their discontent over the new design. Yan Binglu, a 22-year-old iPhone user from Chengdu, capital of southwestern Sichuan province, said she was now rethinking a plan to upgrade her smartphone this year because she found the new interface unappealing. 'This new system looks less beautiful than before,' Yan said. 'I have always updated to the latest iOS on my phone, but I will stay with my current version of iOS this time.'

Hong Kong leader defends new national security conditions for restaurant licence
Hong Kong leader John Lee has defended new national security conditions for licences issued to restaurants and other food and entertainment-related businesses. Speaking at a weekly press conference on Tuesday, the chief executive described the new conditions as 'appropriate and the right thing to do.' The Food and Environmental Hygiene Department (FEHD) is bound by law to safeguard national security, he said, and the 'offending conduct' against national security is 'clearly stated' in the conditions. Lee shrugged off worries raised by some businesses in the city that they may run afoul of the law unwittingly. 'Offending conduct means any offence that endangers national security, or acts and events that are contrary to national security and public interest in Hong Kong. It is very clear,' he said in Cantonese. 'Security is the foundation for development, and we will continue to revamp the laws and the mechanisms of safeguarding national security, he added. FEHD letter Local media reported on Monday that since the end of May, restaurants, entertainment premises, and other businesses had received a letter from the FEHD. According to the FEHD letter, if business licence holders and 'related persons' engage in 'offending conduct' against national security or public interest, authorities could revoke their licence. 'Related persons' include directors, management, employees, agents, and subcontractors, the letter read. One restaurant owner told HKFP on Monday that both of his eateries received the FEHD's letter, postmarked Thursday, May 30. Some eatery owners told Ming Pao that they feared the new conditions were too vague and that they could lose their licence over false allegations. Lee said on Tuesday that the conditions also applied to licences for stalls in Chinese New Year markets. Every Chinese citizen is obliged to safeguard national security, including residents of Hong Kong, he said, citing China's constitution. The government is bound to protect national security, the chief executive added, citing the Beijing-imposed national security law and the homegrown Safeguarding National Security Ordinance, known locally as Article 23. Beijing inserted national security legislation directly into Hong Kong's mini-constitution in June 2020 following a year of pro-democracy protests and unrest. It criminalised subversion, secession, collusion with foreign forces and terrorist acts – broadly defined to include disruption to transport and other infrastructure. The move gave police sweeping new powers and led to hundreds of arrests amid new legal precedents, while dozens of civil society groups disappeared. The authorities say it restored stability and peace to the city, rejecting criticism from trade partners, the UN and NGOs.
