Beijing, China & Kuala Lumpur, Malaysia (AP) - China has urged Malaysia's government to release any information it has regarding the missing Malaysia Airlines jetliner to help narrow the search area.
Friday's appeal by the Foreign Ministry reflects growing frustration among Chinese officials over mixed and conflicting information about the plane, which vanished nearly a week ago with 239 people aboard.
A Foreign Ministry spokesman, Hong Lei, said at a news briefing that Beijing "urgently appeals" for any information regarding the search. Hong said that would "help all sides in the search to make their search more effective and accurately targeted."
Meanwhile, Vietnam says it has downgraded but not stopped its search for the missing jetliner in the South China Sea and has been asked by Malaysian authorities to consider sending planes and ships to the Strait of Malacca.
The statement Friday is a sign that the focus of the search effort is switching to the west of Malaysia, to the strait and further west into the Indian Ocean. It follows remarks by a U.S. official that the Boeing 777 sent signals to a satellite for four hours after the aircraft went missing early Saturday.
If that is true, then it vastly expands the area the lost jet might be.
Vietnam search spokesman Lt. Col. Nguyen Ngoc Son says the status of the hunt has switched from "emergency to regular."
