Full of Dutch nationals, not Chinese. Also, it's unlikely that "Russia" took it down, they merely supplied the weaponry to a bunch of incompetent hotheads who accidentally shot it down.

According to a report by the Berlin-based Correctiv & Der Spiegel [0], it was Russia's 53rd Air Defence Brigade that was directly operating the missile launcher.

Never trust Der Spiegel. Worst magazine ever.

Included Australians too which incensed our government, but what can realistically be done? What's changed as a result?

And I don't think they accidentally shot down the plane. They might've assumed it was a different plane, but from what I could tell, they intended to shoot it down. If I'm trying to avoid accidentally shooting down planes, I'm generally not firing surface-to-air missiles about the place.

It was an arms-length Russian crew then, and that could well have been the case with the other Malaysian plane. Professional support but professional deniability.
