I personally expect some announcement to be made late this year or early 2021. Huawei in general waits very long before it announces products or services, perk of not being a publicly traded company. Just as an interesting example, they seem to be developing a programming language and want to release it early next year, but no public announcement of any kind has been made yet. [4]

You can't sanction public knowledge. The mere idea of such should be ridiculed.
Is it possible the USA government can say that this is open source and free for all to use, except for people in China.
For example, if Red Hat Fedora is open sourced, but Red Hat is a USA company. Then they will still be under USA jurisdiction.
Given all the lies and bullshit coming out of the current administration, I can actually see them doing this.
On a related note, I don't think it's an accident that Apple almost completely avoids talking about "Arm" but instead calls it "Apple Silicon".
