French air crash investigators have met with Malaysian officials to co-ordinate the probe into missing flight MH370.
The fresh impetus is a result of a plane part, thought to belong to a Boeing 777, that washed up on French-governed Reunion in the Indian Ocean.
The component is now in France for analysis.
A suitcase found near the wing portion is also being examined.
Another piece of debris with Chinese and Malaysian writing on it is not thought to be a part of the missing aircraft.
The Malaysian Airlines flight MH 370 was travelling from Kuala Lumpur to Beijing with 239 people on board.
An Australian led hunt for the missing aircraft has been scouring the southern Indian Ocean some 4,000 km east of Reunion.
The huge hi-tech search for the Boeing 777, that went missing in March last year, has so far found nothing.
Investigators can only say with certainty that the plane flew off course before crashing into the sea.
Aviation officials are due to issue a statement on any new developments later in the week.
