Vietnamese officials reportedly found no wreckage in the area where Chinese satellite pictures showed possible debris of the missing Malaysian passenger jet.
Chinese satellite images had pointed to a site in the South China Sea, where the investigators had already searched.
According to news.com.au, the Malaysian air force deployed aircraft to the area in the hope of locating the plane, which had 239 people on board.
China's State Administration for Science, Technology and Industry for National Defence (SASTIND) had published three satellite images that appeared to show three floating objects in the sea, which were captured just a day after the plane disappeared.
However, former aviation director of the US National Transportation Safety Board, Tom Haueter, had been sceptical that the images were connected with the missing jet, saying the aircraft structure that size would sink and not float.
Numerous theories about the plane's disappearance have emerged after it went off radar on Saturday morning just 40 minutes of take off from Kuala Lumpur enroute to Beijing.
The report added that while officials from foreign countries are helping in the search mission, US officials have said that the plane likely stayed in the air for about four hours past the time it reached its last confirmed location.
