Alibaba did not name the core, but they said that it supports ARMv9-A.

ARMv9-A has been announced publicly only this year, while the problems with the rogue ARM China have already begun last year.

Even if technical documentation must have been provided to important customers like Alibaba some times before the public announcement of the ISA, under NDA, it is very unlikely that any IP related to ARMv9 could have been transferred to ARM China in advance, already in 2020, so that they may have any right to license it to customers now.

I believe that Alibaba must have licensed ARMv9-A from the parent company, not from ARM China.

It remains to be seen whether they have licensed the Neoverse N2 core or only the ISA.
