I can assure you, Asian settlers would not have been anywhere as merciful as white Europeans.

I, for one, am not convinced by your assurance.

There's Asian groups in Malaysia and in Indonesia. And there's Indian groups in Fiji. They didn't commit genocide. Racial friction exists, but they moved in and live with the locals, more or less co-operatively. They didn't drive them off the land, or refuse to acknowledge them as human.

On what basis, do you feel so assured of this speculative and specious claim?

Or are you using "I can assure you" to mean you've got no evidence, and it's wrong, but I'd like you to discourage you from questioning it, because I don't want you to notice how paper thin the evidence is?
