A Chinese plane searching for the missing Malaysia Airlines plane has spotted several suspicious floating objects on Monday in remote seas off Australia.

"Searchers saw two relatively big objects with many white smaller ones scattered within a radius of several kilometres, increasing the likelihood that the wreckage of the plane may soon be found",Xinhua news agency said.

Australia said it had been informed and would try to locate the objects.

Flight MH370 disappeared on 8 March while en route from Kuala Lumpur to Beijing, with 239 people on board.

Ten planes were due to scour the southern Indian Ocean area on Monday for possible debris picked up earlier by radar echoes and satellite imagery.

Mean while, Japanese search and rescue teams joined Chinese aircraft Sunday in the hunt for signs of missing Malaysian plane MH370 which has mysteriously vanished.

With Japanese search and rescue teams joining Chinese aircraft Sunday in search operation, a sense of hope is beginning to break through the frustration on the ground at Pearce Airbase in Bullsbrook, western Australia, Xinhua reported.

A further two P3 Orion class planes landed in rural Bullsbrook the unlikely setting for what many hope will be the last stages of the global search -- joining two Chinese IL-76 at the Pearce Airbase 50 km outside of Perth, Australia.

Royal Australian Air Force (RAAF) Wing Commander David Turner welcomed Japanese Maritime Self-Defence Force (JMSDF) officers as an international squadron continue to fly urgent sorties.

The arrival of the upgraded Japanese P3 Orion aircraft comes as the Acting Australian Prime Minister Warren Truss expressed a growing hope after an Australian civilian aircraft reported debris again in the Indian Ocean, including what has been described as a wooden pallet.

Two Chinese IL-76 aircraft have been prepped and sources say they could be in the air early on Monday.

RAAF Group Captain Craig Heap said that the Chinese teams now working with Australian-led sorties were "highly professional".

Aircraft flying on Monday were focused on searching by sight, rather than radar, which can be tricky to use because of the high seas and wind in the area.

"It's a lot of water to look for just perhaps a tiny object," Australian Deputy Prime Minister Warren Truss told Australian Broadcasting Corp. Radio before the Chinese report.

"Today we expect the weather to deteriorate and the forecast ahead is not that good, so it's going to be a challenge, but we will stick at it," he said.

Australia was also analysing French radar images showing potential floating debris that were taken some 850 kms (530 miles) north of the current search area.

"We only recently got this information and we are still examining it," an AMSA spokeswoman told Reuters by telephone. Malaysia said it received the images on Sunday and passed them on to Australia.

Australia has used a U.S. satellite image of two floating objects to frame its search area. A Chinese satellite has also spotted an object floating in the ocean there, estimated at 22 metres long (74ft) and 13 metres (43ft) wide.

It could not be determined easily from the blurred images whether the objects were the same as those detected by the Australian and Chinese search planes, but the Chinese photograph could depict a cluster of smaller objects, said a senior military officer from one of the 26 nations involved in the search.

The wing of a Boeing 777-200ER is approximately 27 metres long and 14 metres wide at its base, according to estimates derived from publicly available scale drawings. Its fuselage is 63.7 metres long by 6.2 metres wide. NASA said it
