I quite agree with this because indeed China's news is still confusing so this is a little difficult to conclude considering they are always like anti to this but on the other hand it does not rule out the possibility that some of the big countries that have been mentioned really have it so this can to be one of their own plans actually to create negative press to make this thing bigger.
They have the authority and power, it is not difficult to raise or manipulate things like this, even though this is still only a rumor and conspiracy, the truth of which is not clear.
