Was China Eastern Airlines flight MU5735 crash intentional?

New speculation is developing that China Eastern flight MU5735 may have been the result of an intentional action by either the crew, an individual or another party. The aircraft was put into a dive.

From Reuters:

“Investigators looking into the crash of a China Eastern Airlines jet are examining the actions of the crew on the flight deck, with no evidence found of a technical malfunction, two people briefed on the matter said.

In mainland China’s deadliest aviation disaster for 28 years, the Boeing 737-800 crashed in the mountains of southern Guangxi on March 21, after a sudden plunge from cruising altitude, killing all 123 passengers and nine crew.”
