Did China Tell 1.4 Billion People to Call the UN if Aliens Land? No.

What happened

In September 2026, a claim spread on Instagram, Reddit and Facebook that the Chinese government had broadcast an emergency warning to its roughly 1.4 billion people. The supposed message was not to communicate with aliens, and to call the United Nations instead. One widely shared Instagram video, quoted by Snopes, said the broadcast “was made as if it were a giant emergency”, delivered by radio, phone alerts, television and messengers sent to rural villages. The supposed script told people to call a number that “will send you to the United Nations desk of the alien communications specialist”.

Snopes published its fact check, by Aleksandra Wrona, on 15 September 2026 and rated the claim false. It found a real story underneath: an international scientific body’s updated rules for researchers who search for alien signals.

Timeline

• 1989: The International Academy of Astronautics (IAA) adopts its first SETI “post-detection” Declaration of Principles. It is revised in 2010.
• October 2010: A Sunday Times report says the head of the UN Office for Outer Space Affairs, Mazlan Othman, will become Earth’s contact for aliens. She denies it at a UN press briefing (Snopes; UN press release of 14 October 2010).

• 6 June 2026: The New York Post covers the update under the headline quote “No Replies Should Be Sent”.
• 7 June 2026: IT Home and Red Star News publish Chinese-language reports. Jingchu Network, part of the Hubei outlet CnHubei, posts a blue-and-yellow graphic on Douyin; the post’s ID dates it to 7 June. China Science Daily, The Paper and CCTV News also cover the declaration.
• 10 June 2026: The Fushun Municipal Science and Technology Bureau (Liaoning) lists an article on the topic under “Science and Technology Work Updates”.
• Late August to September 2026: English-language posts recast the graphic as a Chinese government alert, with a UN hotline added.
• 15 September 2026, 11:16 ET: Snopes publishes its fact check, including the Chinese embassy’s denial.

What believers claim

The claim is that Beijing knows something. In this version, the government sent an Amber Alert-style emergency broadcast, gave out a phone number, and similar messages went out in Japan and South Korea. The Chinese graphic and the appearance of the story on a government website were offered as proof.

What the research found

1. The Chinese embassy denies it. Snopes quotes Liu Chang, a spokesperson for China’s embassy in Washington. He said that “no Chinese government agency issued such a warning, distributed it through national alert channels, or instructed the public to contact the U.N. about extraterrestrial contact”. He added that the rumor “may stem from confusion over a revised SETI protocol issued by the International Academy of Astronautics and reported by Chinese media”.
