"Surprising there is no English language translation of the Chinese update 10th June, despite ..."
The consequence of not giving an english translation next to the national language (either an official ICAO language or not) is that thousands of professionals in the aerospace community are forced to get their own translations or give up. This will only lead to confusion, next to the normal interpretation discussions that you will already have with a formal translation. Making your own translations can be very time consuming, introduces translation and (serious) interpretation errors, and will reduce the time available for other safety work. I don't think it is an exaggeration to say that this is a systemic safety weakness in the global system.
A good translation has access to the actual investigation.
