Ian Wilson, a British video producer, was convinced he had found the missing jet after hours spent searching Google Maps.
Mr Wilson released pictures which seem to show a 70 metre plane – a close match to the 63.7m of MH370’s Boeing 777-200.
He maintains that the ill-fated passenger jet, which completely vanished in 2014 with 239 people on board, now lies around 60 miles west of Cambodia’s capital Phnom Penh.
The images he found, which appear to show a full-length jet partially hidden in foliage, have sparked demand for a thorough investigation among Chinese experts.
Wang Ya’nan, chief editor of Aerospace Knowledge magazine, said the company will help to verify Wilson’s claim.
Mr Wang said: “However, satellite photos alone will not be conclusive, and it will take a professional search team on the ground to lay the claim to rest.”
Their team had already used a space satellite to zoom in on a location in the Cambodian jungle, but they said they had seen no sign of any plane.
However, Chinese newspapers claim the company has still called for a ground search team to explore the spot of the new sighting, the Daily Star reports.
Flight MH370 disappeared while flying from Kuala Lumpur to Beijing on March 8, 2014.
The Malaysian government released findings in July this year which showed their investigations had not brought them any closer to finding out what happened to the passenger jet.
It is thought the Captain Zaharie Ahmad Shah deliberately downed the plane in an act of murder-suicide.
Mr Wilson said his own efforts had achieved what millions of pounds spent in official investigations could not when he uncovered the wreckage online.
He told the Daily Star: “I was on there (Google Earth), a few hours here, a few hours there. If you added it up I spent hours searching for places a plane could have gone down.
“And in the end, as you can see the place where the plane is. It is literally the greenest, darkest part you can see.”
The Bureau of Aircraft Investigations Archives told the Daily Star they could not rule out Ian’s sighting – which is dated 2018 on Google Earth.
