At this level of international politics, sure.

Airbus just had an excessive pitch problem in the A321neo, nearly the same as the 737-MAX troubles. https://simpleflying.com/airbus-a321neo-pitch-problem/ Suddenly, the FAA might take aggressive action to ban that aircraft. Maybe the EASA doesn't really object to the 737-MAX as much as they thought they did.

CAAC would like smooth approvals for Chinese aircraft. Huawei is also having issues. Things could suddenly change after a day of golf at Mar-a-Lago. Lots of things could change, some quietly and some publicly.

The article you linked does not suggest "nearly as bad as the 737-MAX".

I didn't say that either, and it doesn't matter. The problem is of the same general type. It's more than close enough. The FAA should be extra-careful, so maybe the A321neo will get banned. If the EASA wants to take a hard line on safety, they can hardly object.

After a bit of high-level discussion using that leverage, things may change.

These decisions, in all countries, are being made with consideration for international economic implications. The resulting decisions will be given technical justification as required.

But it does matter. This A321neo issue is identified during internal simulated tests, never happened or reported on any commercial or test flight.

The issue consists of the anti-stall protection not being aggressive enough under SPECIFIC circumstances:

- Airplane is in Flare mode - Pilot applies sudden and excessive pitch up - Keeps the pitch during pre stall and stall period

Airline security must never be a matter of putting pressure on an organization.

off topic: you sound like a president who thinks that "maximum pressure" is good, but it has not been proven to work.
