China is now saying it does refer to the July 16 spaceplane test, according to
reports: https://twitter.com/StephenMcDonell/status/1450008739512295427?s=20

About the "suborbital" character of this test: I realised it might not have been
suborbital at all.

While it landed 800 km from the launch site (which was interpreted as
"suborbital"), this could in fact have been at the end of the 1st revolution.

I was indeed able to create a ~41.2 deg inclined hypothetical TLE for a Jiuquan
launch that at the end of the 1st rev ends up near the indicated landing area
(Alxa League).
