China is turning to artificial intelligence to rile up U.S. voters and stoke divisions ahead of the country’s 2024 presidential elections, according to a new report.
Threat analysts at Microsoft warned in a blog post Thursday that Beijing has developed a new artificial intelligence capability that can produce “eye-catching content” more likely to go viral compared to previous Chinese influence operations.
According to Microsoft, the six-month-long effort appears to use AI-generators, which are able to both produce visually stunning imagery and also to improve it over time.
“We have observed China-affiliated actors leveraging AI-generated visual media in a broad campaign that largely focuses on politically divisive topics, such as gun violence, and denigrating U.S. political figures and symbols,” Microsoft said.
“We can expect China to continue to hone this technology over time, though it remains to be seen how and when it will deploy it at scale,” it added.
China on Thursday dismissed Microsoft’s findings.
“In recent years, some western media and think tanks have accused China of using artificial intelligence to create fake social media accounts to spread so-called ‘pro-China’ information,” Chinese Embassy spokesperson Liu Pengyu told VOA in an email. “Such remarks are full of prejudice and malicious speculation against China, which China firmly opposes.”
According to Microsoft, Chinese government-linked actors appear to be disseminating the AI-generated images on social media while posing as U.S. voters from across the political spectrum. The focus has been on issues related to race, economic issues and ideology.
In one case, the Microsoft researchers pointed to an image of the Statue of Liberty altered to show Lady Liberty holding both her traditional torch and also what appears to be a machine gun.
The image is titled, “The Goddess of Violence,” with another line of text warning that democracy and freedom is “being thrown away.”
But the researchers say there are clear signs the image was produced using AI, including the presence of more than five fingers on one of the statue’s hands.
In any case, the early evidence is that the efforts are working.
“This relatively high-quality visual content has already drawn higher levels of engagement from authentic social media users,” according to a Microsoft report issued along with the blog post.
“Users have more frequently reposted these visuals, despite common indicators of AI-generation,” the report added.
Additionally, the Microsoft report says China is having Chinese state media employees masquerade as “as independent social media influencers.”
These influencers, who appear across most Western social media sites, tend to push out both lifestyle content and also propaganda aimed at localized audiences.
Microsoft reports the influencers have so far built a following of at least 103 million people in 40 languages.

Japan launched a rocket Thursday carrying an X-ray telescope that will explore the origins of the universe as well as a small lunar lander.
The launch of the HII-A rocket from Tanegashima Space Center in southwestern Japan was shown on live video by the Japan Aerospace Exploration Agency, known as JAXA.
“We have a liftoff,” the narrator at JAXA said as the rocket flew up in a burst of smoke and then flew over the Pacific.
Thirteen minutes after the launch, the rocket put into orbit around Earth a satellite called the X-Ray Imaging and Spectroscopy Mission, or XRISM, which will measure the speed and makeup of what lies between galaxies.
That information helps in studying how celestial objects were formed, and hopefully can lead to solving the mystery of how the universe was created, JAXA said.
In cooperation with NASA, JAXA will look at the strength of light at different wavelengths, the temperature of things in space and their shapes and brightness.
David Alexander, director of the Rice Space Institute at Rice University, believes the mission is significant for delivering insight into the properties of hot plasma, or the superheated matter that makes up much of the universe.
Plasmas have the potential to be used in various ways, including healing wounds, making computer chips and cleaning the environment.
“Understanding the distribution of this hot plasma in space and time, as well as its dynamical motion, will shed light on diverse phenomena such as black holes, the evolution of chemical elements in the universe and the formation of galactic clusters,” Alexander said.
Also aboard the latest Japanese rocket is the Smart Lander for Investigating Moon, or SLIM, a lightweight lunar lander. The Smart Lander won’t make lunar orbit for three or four months and would likely attempt a landing early next year, according to the space agency.
The lander successfully separated from the rocket about 45 minutes after the launch and proceeded on its proper track to eventually land on the moon. JAXA workers applauded and bowed with each other from their observation facility.
JAXA is developing “pinpoint landing technology” to prepare for future lunar probes and landing on other planets. While landings now tend to be off by about 10 kilometers (6 miles) or more, the Smart Lander is designed to be more precise, within about 100 meters (330 feet) of the intended target, JAXA official Shinichiro Sakai told reporters ahead of the launch.
That allows the box-shaped gadgetry to find a safer place to land.
The move comes at a time when the world is again turning to the challenge of going to the moon. Only four nations have successfully landed on the moon, the U.S., Russia, China and India.
Last month, India landed a spacecraft near the moon’s south pole. That came just days after Russia failed in its attempt to return to the moon for the first time in nearly a half century. A Japanese private company, called ispace, crashed a lander in trying to land on the moon in April.
Japan’s space program has been marred by recent failures. In February, the H3 rocket launch was aborted for a glitch. Liftoff a month later succeeded, but the rocket had to be destroyed after its second stage failed to ignite properly.
Japan has started recruiting astronaut candidates for the first time in 13 years, making clear its ambitions to send a Japanese to the moon.
Going to the moon has fascinated humankind for decades. Under the U.S. Apollo program, astronauts Neil Armstrong and Buzz Aldrin walked on the moon in 1969.
The last NASA human mission to the moon was in 1972, and the focus on sending humans to the moon appeared to wane, with missions being relegated to robots.

Earth has sweltered through its hottest Northern Hemisphere summer ever measured, with a record warm August capping a season of brutal and deadly temperatures, according to the World Meteorological Organization.
Last month was not only the hottest August scientists ever recorded by far with modern equipment, it was also the second hottest month measured, behind only July 2023, WMO and the European climate service Copernicus announced Wednesday.
August was about 1.5 degrees Celsius warmer than pre-industrial averages. That is the threshold that the world is trying not to pass, though scientists are more concerned about rises in temperatures over decades, not merely a blip over a month’s time.
The world’s oceans — more than 70% of the Earth’s surface — were the hottest ever recorded, nearly 21 C, and have set high temperature marks for three consecutive months, the WMO and Copernicus said.
“The dog days of summer are not just barking, they are biting,” United Nations Secretary-General Antonio Guterres said in a statement. “Climate breakdown has begun.”
So far, 2023 is the second hottest year on record, behind 2016, according to Copernicus.
Scientists blame ever warming human-caused climate change from the burning of coal, oil and natural gas with an extra push from a natural El Nino, which is a temporary warming of parts of the Pacific Ocean that changes weather worldwide. Usually an El Nino, which started earlier this year, adds extra heat to global temperatures but more so in its second year.
Climatologist Andrew Weaver said the numbers announced by WMO and Copernicus come as no surprise, bemoaning how governments have not appeared to take the issue of global warming seriously enough. He expressed concern that the public will just forget the issue when temperatures fall again.
“It’s time for global leaders to start telling the truth,” said Weaver, a professor at the School of Earth and Ocean Sciences at the University of Victoria in Canada. “We will not limit warming to 1.5 C; we will not limit warming to 2.0 C. It’s all hands on deck now to prevent 3.0 C global warming — a level of warming that will wreak havoc worldwide.”
Copernicus, a division of the European Union’s space program, has records going back to 1940, but in the United Kingdom and the United States, global records go back to the mid-1800s and those weather and science agencies are expected to soon report that the summer was a record-breaker.
“What we are observing, not only new extremes but the persistence of these record-breaking conditions, and the impacts these have on both people and planet, are a clear consequence of the warming of the climate system,” Copernicus Climate Change Service Director Carlo Buontempo said.
Scientists have used tree rings, ice cores and other proxies to estimate that temperatures are now warmer than they have been in about 120,000 years. The world has been warmer before, but that was before human civilization, seas were much higher and the poles were not icy.
So far, daily September temperatures are higher than what has been recorded before for this time of year, according to the University of Maine’s Climate Reanalyzer.
While the world’s air and oceans were setting records for heat, Antarctica continued to set records for low amounts of sea ice, the WMO said.
“Antarctic sea ice extent was literally off the charts, and the global sea surface temperature was once again at a new record,” WMO’s secretary-general, Petteri Taalas, said in a statement released to the media. “It is worth noting that this is happening BEFORE we see the full warming impact of the El Nino event, which typically plays out in the second year after it develops.”
A strong El Nino coincided with the all-time high temperatures in 2016. The U.N. weather agency earlier this year rolled out predictions that suggest Earth would within the next five years have a year that averages 1.5 degrees Celsius warmer than in the mid-19th century. Each year at or near 1.5 matters.
It also predicted 98% chance of breaking the 2016 record between now and 2027.
The new readings on high global temperatures came as WMO released Wednesday its latest bulletin on air quality and climate, noting that extreme heat, compounded by wildfires and desert dust, has had a measurable impact on air quality, human health and the environment.
WMO scientific adviser Lorenzo Labrador lamented the deteriorating air quality around the globe and cited “record-breaking wildfire season” in many parts of the world, including western Canada and Europe.
“If heat waves increase as a result of El Nino, we may probably expect a further degradation in air quality as a whole,” he said.
