We can only wait to see if this is true. Another possibility could be that it was an answer to USA's government considering a ban on chinese models. In this way, he fueled the discussion around the importance of open weight models.
Xi actually said that models of the strength to pose security issues will be permanent state secrets -- in the same speech that the first western takes translated as actually using the words 'open weights' which of course nowhere appeared. Now: when will "models of the strength to pose security issues" appear? Maybe my inference 'months' is wrong, but they seem to be advancing rapidly.
The administration blather about banning open weights is characteristically confused. Xi has already stated (what is obvious) that he will ban security-endangering weights and keep them a state secret.
