The search area for the missing Malaysia Airlines MH370 has grown to an even wider scope at 2.24 million nautical square miles, which Malaysian officials said is roughly equivalent to the size of Australia.

Malaysia officials called on the search teams to share whatever data they could gather in the ongoing search.

China has sent 10 ships and 21 satellites at the disposal of the search teams.

Meanwhile, all the Chinese passengers aboard the missing Malaysia Airline MH 370 were found to have no connections to terrorism activities or hijacking.

The background checks were done by Beijing on 154 Chinese nationals as part of its ongoing investigation on the missing jetliner.

According to state news agency Xinhua, this new information eliminates the speculation that Uyghur separatists from China's Xinjiang province were involved in the disappearance of Malaysia Airlines MH370.

"The background checks on Chinese nationals didn't uncover any evidence suggesting they were involved in hijacking or an act of terrorism against the plane," according to Xinhua, quoting Chinese Ambassador to Malaysia Huang Huikang.

Malaysia has conducted its own background check on its 50  passengers and urged countries who have their respective nationals onboard to do the same.

Malaysian authorities have searched the homes of the pilot and co-pilot, taking away the pilot's flight simulator, and said the investigations will also include background checks on the ground crew.

Malaysia officials said the plane was deliberately diverted from its path by "someone who took action" and that the two communication systems of the missing plane were "deliberately" shut down.

To date, around 26 countries are helping out in the search which encompasses 11 countries. Huikang  said Chinese experts had begun searching for the plane in its territory.

Malaysia Airlines has been helping the families of passengers deal with their situation and has set up 24-hour operations centers in Beijing and Kuala Lumpur to provide care to families of the crew members and the passengers.

More than 100 staff and caregivers have been sent by Malaysia Airlines to Beijing to attend to the needs of the families of the passengers.
