How do you comprehend this remark?

Taken as it is written, the group of people speaking are very serious about the claim they are making, that what is feared in this world are the Chinese characters 'ren zhen'.

This is a very idiosyncratically written sentence.

Was it was written for purposes of teaching semantics? If not, then the sentence could be rewritten for better clarity.

Not for teaching semantics


No.
The part in bold type means that "we are serious about in doing anything, everything". The two words just express our serious attitude.

So what improvement you suggest? Thanks

The world should fear the Chinese because they are very serious.

That's my best guess, without being at all sure of the meaning.

Well, it isn't clear what, exactly, you are trying to say.
