China's FAST radio telescope or the "Sky Eye" began its operations in January 2020 and is known as the largest of its kind. The 1,600 ft diameter telescope invited scholars from all over the world to submit their applications to utilize the telescope that had claimed to have heard alien life. 

It was Chinese state media outlet Science and Technology Daily that reported that the chief scientist of the China Extraterrestrial Civilization Research Group at Beijing Normal University, Zhang Tongjie had noted "possible technological traces" from aliens civilizations. 

Well, the verdict is in, professor Zhang Tongjie has now told Newsweek, "I did not say it was an extraterrestrial (ET) signal. These signals are from radio interference; they are due to radio pollution from Earthlings, not from ET. The technical term we use is 'RFI'—Radio frequency interference. RFI can come from cell phones, TV transmitters, radar, satellites, as well as electronics and computers near the observatory that produce weak radio transmissions."
