China on Tuesday urged international organizations and related countries to provide information that may help in the search for the missing Malaysia Airlines Flight MH370.

"It is an international search. China hopes international organizations and countries will provide Malaysia and China with valuable information to help us conduct better targeted search work," said Foreign Ministry spokesman Hong Lei.

Hong made the remarks at a regular press briefing while answering a question on whether China will demand more evidence from Britain.

Late on Monday, Malaysian Prime Minister Najib Razak said the missing plane "ended" in the southern Indian Ocean, based on conclusion by the British Air Accidents Investigation Branch and Inmarsat, a Britain-based satellite company that provided the satellite data.

"We are highly concerned with Malaysia's conclusion, and have demanded full information and the evidence that supports the conclusion," Hong said.

He also urged Malaysia to continue to coordinate the international search.

China has spared no efforts in the search for the missing plane, Hong said, adding that Chinese vessels are continuing to arrive in the target waters.

On Tuesday, Chinese icebreaker Xuelong reached the area where Chinese search planes spotted suspicious objects, while the merchant ship Zhonghaishaohua arrived in waters where French satellites spotted suspicious items, according to the spokesman.

He said three Chinese naval ships, including amphibious transport dock Kunlunshan, supply ship Qiandaohu and missile destroyer Haikou, are also expected to arrive in the target area on Tuesday.

Chinese vessels Haixun 01 and Nanhaijiu 101 are heading for the area where Australian satellite spotted suspicious items, and two Chinese IL-76 planes conducted two rounds of searches in the area on Monday, Hong added.

Meanwhile, he said, the China Maritime Search and Rescue Center has coordinated eight Chinese merchant ships to change their courses and they have scoured the Bay of Bengal and waters off Indonesia and Australia, covering an area of 15,380 square km.

Another 20 fishing vessels working in the central Indian Ocean have participated into the search, said Hong, although "so far, they have found nothing linked to the missing plane."

Flight MH370, a Boeing 777-200ER, went missing on its way to Beijing on March 8, shortly after taking off from Kuala Lumpur. The plane was carrying 12 crew and 227 passengers, including 154 Chinese.

The search for the missing passenger jet is in its third week.
