Despite the progress being made, experts have warned that the search for Malaysia Airlines flight MH370 will be a long process due to its complexity.
Because of the contradictory information coming from the Malaysian government and Malaysia Airlines about Flight MH370, the anger of the families of the 154 Chinese passengers on the plane is growing - relatives of the missing passengers held a protest in front of the Malaysian embassy in Beijing - and there has been an outpouring of anti-Malaysia sentiments via social media in China.
Weeks have passed since the world lost contact with Malaysia Airlines flight MH370 and its 239 passengers and crew.
Long-term cooperation between China and Malaysia is unlikely to be affected by the missing flight, observers say, urging a rational, calm attitude toward people and organizations of the two countries.
A small number of netizens have vented their anger and even verbally abused some innocent Chinese Malaysian singers because of what they perceive as the Malaysian government's mishandling of the MH370 situation.
Over the past three weeks, the fate of the 239 people, including 154 Chinese compatriots, on board Air Malaysia Flight MH370 has lain heavy on the hearts of all Chinese people. However, today no matter how distressed we are and how many details that are not clear, it is certain that flight MH370 crashed in the Indian Ocean and no one on board survived. All the related parties can do is to continue to search for the wreckage, carry on negotiations with the Malaysian side for more information and prepare to make arrangements for funerals.
China and other countries have employed satellites as well as aircraft and ships in the search for the missing Malaysia Airline plane.
Malaysian Prime Minister Najib Razak delivered his sadness for the lost lives and his condolences for the relatives during his announcement on Monday.
Changes in information, miscommunication and speculation compound the search for Malaysia Airlines jet which vanished with 239 on board.
Undersea search expert who co-led the hunt for downed Air France Flight 447 called the MH370 case "extremely unusual because there has been no confirmed evidence of the plane at all."
The disappearance of a Malaysian plane has prompted calls for in-flight streaming of black box data over remote areas.
