It appears they are suing the US entity. They do not say if they commenced actions overseas. If they only use the US entity then only that one will be affected.

They are HQ in Hong Kong and fortunately, still do have robust enforcement of copyright laws. You can enforce foreign judgments, particularly American ones through reciprocal enforcement arrangements. This is complicated and depends on which entities they sue.

Presumably their lawyers would have advised them on this properly and know the situation better than we do.
