Deep-water search missing Malaysia Airlines flight MH370 ended Tuesday without a trace of the plane was found disappeared in 2014 with 239 people aboard the three countries said included in the survey.
The MH370 flight location has become one of the biggest mysteries in the aviation world since the plane, a Boeing 777, disappeared on the way to Beijing from the capital of Malaysia Kuala Lumpur.
Australian and Chinese authorities said,"Despite every effort using the best science available ... the search has not been able to locate the aircraft".
"The decision to suspend the underwater search has not been taken lightly nor without sadness."
The latest research vessel left the area on Tuesday, according to the three countries, according to the area of 120,000 square kilometers (46,000 square miles) to explore the Indian Ocean seabed, which was the focus of almost three years.
Malaysia, Australia and China agreed in July to seek $ 145,000,000 to be made when the plane was found, or whether new evidence that there was a clue as to its whereabouts after the area could offer tested.
Australia last month rejected the recommendation of a more northern researcher to research the change, say, no new evidence has emerged to support this.
If the accident was competing theories as to whether one, both or none of the pilots in control were when he was kidnapped - or any death on board and the aircraft was not controlled when it came to water.
In addition to the mystery, the researchers believe that someone deliberately distracted the transponder, the aircraft have rolled out thousands of miles across the Indian Ocean.
A support group called the Voice-370 close relatives said in a statement that the researchers could not get out unresolved issue.
"In our view, extending the search to the new area defined by the experts is an inescapable duty owed to the flying public in the interest of aviation safety," Voice 370 said.
