None more so

Is 'none more so than' a phrase? If so, what does it mean? I saw this in the following paragraph.

"So auto manufacturers are expecting great things from China and none more so than luxury car-makers."

It is no more so than "auto manufacturers are expecting". Well... maybe a tiny bit.
None = not any (auto manufacturers is understood)
more = more
so = in that way (are expecting great things)
than = than
Not any auto manufacturers are expecting great things more than luxury car-makers (are).
