Let me frame it like this;

If GLM-6 is made publicly available[1], will that change your predictions of how they will behave in the future, or your understanding of their motivations in the present?

[1] I am certainly no expert of Chinese AI policy, but I fear you are attributing US values and goals to the Chinese govt.

From where I stand, they appear to be very different though. China is seeking to increase influence, whereas the US (seems to be) seeking to become more insular. China is actively persuing the world-leader role, while the US dismantles soft-power tools like USaid, and alienates countries pursuing obviously flawed military excursions.
