Chinese President Xi Jinping has appointed a special envoy to Malaysia to oversee matters concerning the missing Malaysia Airlines flight 370.
Zhang Yesui, a vice foreign minister, will soon fly to Kuala Lumpur to be responsible for consultations with the Malaysian side.
Zhang has been tasked with learning the relevant information and urging the Malaysian side to better handle the situation, according to an official statement released on Tuesday afternoon.
Xi, who is attending the Nuclear Security Summit in The Hague, Netherlands, has been openly concerned about the status of the 239 people onboard MH370, including 154 Chinese.
He has also reportedly been following the search efforts for the plane and coordinating the deployment of Chinese resources.
China demands information on MH370
In a separate statement, Chinese Premier Li Keqiang said China will ask Malaysia to provide more detailed and accurate information on the plane, according to a government microblog account.
Li said the most important task at present is to search for the missing plane and he expressed sympathy to the family members.
At a regular press briefing Tuesday, China's Foreign Ministry spokesman urged international organizations and related countries to provide information that may help in the search for 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.
Late 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.
"This is a remote location, far from any possible landing sites," Razak said in a statement. "It is therefore, with deep sadness and regret, that I must inform you that, according to this new data, flight MH370 ended in the southern Indian Ocean."
The announcement sparked anger among relatives as they thought Malaysian authorities mishandling the matter of flight MH370.
An estimated 300 distressed family and friends of the Chinese passengers on the missing jetliner massed in front of the embassy Tuesday to demand answers and ask for more information.
