Qing Dynasty annexed Xinjiang, Taiwan, Tibet, Mongolia, as well as large chunks of Central Asia, and fought with Sikhs over Kashmir. Looks like a good case of imperial expansion to me.
They also annexed China. That's your idea of "Chinese expansionism"?

The person you replied to wrote: none of them were products of “Han Chinese imperialism.”
This is correct, since the Qing Dynasty was led by the Manchus (https://en.wikipedia.org/wiki/Qing_dynasty), not by the Han Chinese.
