    China Crash
In summary: No, it's a specific condition where you have a flow separation over the top surface due to too high of an angle of attack. Diving toward Earth and having the wing produce no lift because zero effective angle of attack is not a stall.

Actually, wall street journal does report about flight data:

WSJ behind paywall when I attempt to read article. Reuters refers to the WSJ reporting with additional interviews.
One source told Reuters that investigators were looking at whether the crash was a "voluntary" act involving crew inputs to the controls, though that does not necessarily mean the dive was intentional.

The cockpit voice recorder was damaged during the crash and it is unclear whether investigators have been able to retrieve any information from it.

The first couple of paragraphs and the summary statement under the headline succinctly state the US position:

Summary: Flight data suggests that someone in the cockpit of the Boeing 737-800 that crashed in March put the aircraft into a near-vertical descent, according to a preliminary U.S. assessment.

Article: Flight data indicates someone in the cockpit intentionally crashed a China Eastern jet earlier this year, according to people familiar with U.S. officials’ preliminary assessment of what led to the accident.

The Boeing 737-800 was cruising at high altitude when it suddenly pitched into a near-vertical descent, plummeting into a mountain at extreme speed. Data from a black box recovered in the crash suggests inputs to the controls pushed the plane into the fatal dive, these people said.

Hmm interesting, if I use my own link above, I now also see the paywall. But earlier I didn't. Apparently you have an X amount of articles you are allowed to read in Y amount of time.
