Two Chinese ships in search of missing Malaysia Airlines Flight MH370 in the southern Indian Ocean retrieved a beacon late Tuesday, said an embedded Xinhua reporter.

The crews aboard Jinggangshan and Donghaijiu 101 told Xinhua that the beacon might be cast by aircraft involved in the hunt for the ill-fated Boeing 777 jetliner but confirmation was needed.

The two ships are among the seven Chinese vessels currently scouring waters some 2,000 kilometers west of the western Australian port city of Perth. Two Chinese IL-76 planes are also assisting the undertaking.

Meanwhile, a three-ship Chinese naval flotilla previously deployed in the Gulf of Aden for escort missions teamed up with Chinese patrol vessel Haixun 31 on Tuesday to search for the missing plane south of Australia's Christmas Island.

Despite massive multinational efforts, no hard evidence has so far been acquired about the whereabouts of MH370, which disappeared early March 8 while carrying 239 people -- including 154 Chinese passengers -- from Kuala Lumpur to Beijing.
