Well, the Chinese don't seem to agree.

Not to say it wouldn't be an easy argument in the trade war game.
The Chinese and others are responding to the concerns of their constituents or perhaps to another agenda, as you note. That action is immaterial to determining the cause(s) of this and the Lion Air crash.

Boeing created a fundamentally less stable plane (source) in order to realize a few percent efficiency improvement. To compensate for the inherent flaw, they implemented a new automated correction system with a single point of failure and not documented in pilot manuals or trainings.

There are several similarities between the Lion flight and the Ethiopian flight. Both had erratic speed and climb/elevation readings, both the pilots requested to return to origin, and both crashed in a steep drop within 5-15 minutes of takeoff.

The automated system mentioned above seems by all accounts to be the primary cause of the Lion pilots' struggle with the aircraft. After the crash the system became widely known, and while I hope all pilots of that model received training on disabling the automated system, but from what I can find Boeing has not issued any change to the behaviour of the system, simpler override procedure, or a secondary point of failure.

Boeing is being sued in US courts by the families of Lion passengers, but I think Boeing was very "lucky" that Lion JT610 was operated by an airline with an already dubious safety record and the passengers were all Indonesian and just one Italian. In the case of the Ethiopian flight, I have seen reports that 35 nationalities were on-board, including many Americans and Europeans, so this crash is likely to receive a much higher level of attention and scrutiny in international media.

Singapore has grounded all Boeing 737 MAX aircraft, including those flying in and out of Singapore. This follows previous groundings by China and Indonesia This could cause some delays. If you're flying in the region you should check with your airlines.

Some operators of the aircraft in the region and number of planes grounded:

Indonesia:
Lion Air (8)
Garuda (1)

Singapore:
Silk Air (17)

China:
Air China (15)
China Eastern (14)
China Southern (24)
Xiamen Airlines (10)

As did the EU.

Some flights were forced to land on the spot, like for instance one from the Red Sea to Amsterdam; the flight had to land in Bologna Italy and the people needed to take another flight to their final destination the next day. (Now that seems a bit like overkill; not allowed to continue 1 more hour?)

Ha. After the American and Canadian decisions now Boeing themselves advise to ground these planes.

I doubt if the switch will improve the Lion Air safety record.

Turkish Airlines to open direct flights between Denpasar and Istanbul. Should be very popular as Turks and Indonesians can visit either country without visa. Also good connection options from Istanbul to Europe, Middle East and North Africa.
