WASHINGTON — “I love you, China. My dear mother,” former U.S. President Donald Trump, standing in front of a mic at a lectern, appears to sing in perfect Mandarin.

“I cry for you, and I also feel proud for you,” Vice President Kamala Harris, Trump’s Democratic opponent in this year’s election, appears to respond, also in perfect Mandarin. Trump lets out a smile as he listens to the lyric.

The video has received thousands of likes and tens of thousands of reposts on Douyin, China’s variation of TikTok.

“These two are almost as Chinese as it gets,” one comment says.

Neither Trump nor Harris knows Mandarin. And the duet shown in the video has never happened. But recently, deepfake videos, frequently featuring top U.S. leaders, including President Joe Biden, singing Chinese pop songs, have gone viral on the Chinese internet.

Some of the videos have found their way to social media platforms not available in China, such as Instagram, TikTok and X.

U.S. intelligence officials and experts have long warned about how China and other foreign adversaries have been implementing generative AI in their disinformation effort to disrupt and influence the 2024 presidential election.

“There has been an increased use of Chinese AI-generated content in recent months, attempting to influence and sow division in the U.S. and elsewhere,” a Microsoft report on China’s disinformation threat said in April.

Few of the people who saw the videos of the American leaders singing in Chinese, however, were convinced that they were real, based on what users wrote in the comments. The videos themselves do not contain misinformation, either.

Instead, these videos and their popularity reflect, at least in part, a sense of cultural confidence in Chinese netizens in the age of perpetually intensifying U.S.-China competitions, observers told VOA Mandarin.

By making the likes of Biden and Trump sing whatever Chinese songs the creators of the videos want them to sing, they can “culturally domesticate powerful Americans,” said Alexa Pan, a researcher on China’s AI industry for ChinaTalk, an influential newsletter about China and technology.

“Making fun of U.S. leaders might be especially politically acceptable to and popular with Chinese viewers,” she said.

Political opponents sing about friendship

Videos of American leaders singing in Chinese started to spread on Chinese social media in May. In many of the videos featuring Biden and Trump, creators made the two politically opposed men sing songs about friendship.

After Biden announced his withdrawal from the presidential race in July, one viral video had him sing to Trump, “Actually I don’t want to leave. Actually, I want to stay. I want to stay with you through every spring, summer, autumn and winter,” to which Trump appeared to sing, “You have to believe me. It won’t take long before we can spend our whole life together.”

“Crying eyes,” one Chinese netizen commented sarcastically. “They must have gotten along really well.”

Another such video posted on Instagram received mostly positive reactions. Some users said it was a stark contrast to the bitterness that has permeated U.S. politics.

“Made me laugh,” an Instagram user wrote. “Wouldn’t that be so refreshing to actually have them sing like that together?”

Easy to make

After reviewing some of the videos, Pan, of ChinaTalk, told VOA Mandarin that she believes they were quite easy to make.

Obvious flaws in the videos, including body parts occasionally blending into the background, suggest they were created with simple AI technology, Pan said.

“One could generate these videos on the many AI text-to-video generation platforms available in China,” she wrote in an e-mail.

On the Chinese internet, there are countless tutorials on how to make AI-generated videos using popular lip-syncing AI models, such as MuseTalk, released by Chinese tech giant Tencent, and SadTalker, developed by Xi’an Jiaotong University, a research-focused university in northwestern China.

One Douyin account reviewed by VOA Mandarin has pumped out over 200 videos of American leaders singing in Chinese since May. One of the account’s videos was even reposted by the Iranian embassy.

Chinese leaders off-limits

The release of ChatGPT by OpenAI in 2022 has triggered a global AI frenzy, with China being one of the leading countries developing the technology. The United Nations said in July that China had requested the most patents on generative AI, with the U.S. being a distant second.

On the Chinese internet, the obsession has been particularly strong with deepfakes, which can be used to manipulate videos, images and audio of people to make them appear to say or sing things that they have not actually uttered.

Some deepfake videos are made mostly for fun, such is the case with Biden and Trump singing Chinese songs. But there have also been abuses of the technology. Earlier this year, web users in China stole a Ukrainian girl’s image and turned her into a “Russian beauty” to sell goods online.

 China has released strict regulations on deepfakes. A 2022 law states that the technology cannot be used to “endanger the national security and interests, harm the image of the nation, harm the societal public interest, disturb economic or social order, or harm the lawful rights and interests of others.”

Yang Han, an Australian commentator who used to work for China’s Foreign Ministry, told VOA Mandarin that the prominence of U.S leaders and the absence of Chinese leaders in these viral AI videos reflects a lack of political free speech in China.

He said that it reminds him of a joke that former U.S. President Ronald Reagan used to tell during the Cold War.

“An American and a Russian compare with each other whose country has more freedom,” Yang said, relaying the joke. “The American says he can stand in front of the White House and call Reagan stupid. The Russian dismisses it and says he can also stand in front of the Kremlin and call Reagan stupid.”

tokyo — A long robot entered a damaged reactor at Japan’s Fukushima nuclear power plant on Tuesday, beginning a two-week, high-stakes mission to retrieve for the first time a tiny amount of melted fuel debris from the bottom.

The robot’s trip into the Unit 2 reactor is a crucial initial step for what comes next — a daunting, decades-long process to decommission the plant and deal with large amounts of highly radioactive melted fuel inside three reactors that were damaged by a massive earthquake and tsunami in 2011. Specialists hope the robot will help them learn more about the status of the cores and the fuel debris.

Here is an explanation of how the robot works, its mission, significance and what lies ahead as the most challenging phase of the reactor cleanup begins.

What is the fuel debris?

Nuclear fuel in the reactor cores melted after the magnitude 9.0 earthquake and tsunami in March 2011 caused the Fukushima Daiichi nuclear plant’s cooling systems to fail. The melted fuel dripped down from the cores and mixed with internal reactor materials such as zirconium, stainless steel, electrical cables, broken grates and concrete around the supporting structure and at the bottom of the primary containment vessels.

The reactor meltdowns caused the highly radioactive, lava-like material to spatter in all directions, greatly complicating the cleanup. The condition of the debris also differs in each reactor.

Tokyo Electric Power Company Holdings, or TEPCO, which manages the plant, says an estimated 880 tons of molten fuel debris remains in the three reactors, but some experts say the amount could be larger.

What is the robot’s mission?

Workers will use five 1.5-meter-long pipes connected in sequence to maneuver the robot through an entry point in the Unit 2 reactor’s primary containment vessel. The robot itself can extend about 6 meters inside the vessel. Once inside, it will be maneuvered remotely by operators at another building at the plant because of the fatally high radiation emitted by the melted debris.

The front of the robot, equipped with tongs, a light and a camera, will be lowered by a cable to a mound of melted fuel debris. It will then snip off and collect a bit of the debris — less than 3 grams). The small amount is meant to minimize radiation dangers.

The robot will then back out to the place it entered the reactor, a roundtrip journey that will take about two weeks.

The mission takes that long because the robot must make extremely precise maneuvers to avoid hitting obstacles or getting stuck in passageways. That has happened to earlier robots.

TEPCO is also limiting daily operations to two hours to minimize the radiation risk for workers in the reactor building. Eight six-member teams will take turns, with each group allowed to stay maximum of about 15 minutes.

What do officials hope to learn?

Sampling the melted fuel debris is “an important first step,” said Lake Barrett, who led the cleanup after the 1979 disaster at the U.S. Three Mile Island nuclear plant for the Nuclear Regulatory Commission and is now a paid adviser for TEPCO’s Fukushima decommissioning.

While the melted fuel debris has been kept cool and has stabilized, the aging of the reactors poses potential safety risks, and the melted fuel needs to be removed and relocated to a safer place for long-term storage as soon as possible, experts say.

An understanding of the melted fuel debris is essential to determine how best to remove it, store it and dispose of it, according to the Japan Atomic Energy Agency.

Experts expect the sample will also provide more clues about how exactly the meltdown 13 years ago played out, some of which is still a mystery.

The melted fuel sample will be kept in secure canisters and sent to multiple laboratories for more detailed analysis. If the radiation level exceeds a set limit, the robot will take the sample back into the reactor.

“It’s the start of a process. It’s a long, long road ahead,” Barrett said in an online interview. “The goal is to remove the highly radioactive material, put it into engineered canisters … and put those in storage.”

For this mission, the robot’s small tong can only reach the upper surface of the debris. The pace of the work is expected to pick up in the future as more experience is gained and robots with additional capabilities are developed.

What’s next?

TEPCO will have to “probe down into the debris pile, which is over a meter thick, so you have to go down and see what’s inside,” Barrett said, noting that at Three Mile Island, the debris on the surface was very different from the material deeper inside. He said multiple samples from different locations must be collected and analyzed to better understand the melted debris and develop necessary equipment, such as stronger robots for future larger-scale removal.

Compared to collecting a tiny sample for analysis, it will be a more difficult challenge to develop and operate robots that can cut larger chunks of melted debris into pieces and put that material into canisters for safe storage.

There are also two other damaged reactors, Unit 1 and Unit 3, which are in worse condition and will take even longer to deal with. TEPCO plans to deploy a set of small drones in Unit 1 for a probe later this year and is developing even smaller “micro” drones for Unit 3, which is filled with a larger amount of water.

Separately, hundreds of spent fuel rods remain in unenclosed cooling pools on the top floor of both Unit 1 and 2. This is a potential safety risk if there’s another major quake. Removal of spent fuel rods has been completed at Unit 3.

When will the decommissioning be finished?

Removal of the melted fuel was initially planned to start in late 2021 but has been delayed by technical issues, underscoring the difficulty of the process. The government says decommissioning is expected to take 30-40 years, while some experts say it could take as long as 100 years.

Others are pushing for an entombment of the plant, as at Chernobyl after its 1986 explosion, to reduce radiation levels and risks for plant workers.

That won’t work at the seaside Fukushima plant, Barrett says.

“You’re in a high seismic area, you’re in a high-water area, and there are a lot of unknowns in those (reactor) buildings,” he said. “I don’t think you can just entomb it and wait.”
