Experts are trying to determine whether the part comes from the plane, which disappeared on March 8, 2014, en route from Kuala Lumpur to Beijing with 239 people on board. The fragment was found on the French Indian Ocean island of Reunion and returned to the French mainland.
Malaysian officials left Monday's meeting without comment.
Air safety investigators, including one from Boeing, have identified the component as a flaperon from the trailing edge of a Boeing 777 wing. Flight 370 is the only missing 777 and many are convinced the flap comes from the ill-fated jet.
