On GUI frames Emacs takes the width of each character in pixels from
the font that is being used.  So if you want each Chinese character to
take exactly 2 character cells of an ASCII character, you need to find
a pair of fonts that satisfy this relation.  Because the font used for
ASCII varies between users, and the font used for Chinese probably
varies as well, I don't think I see how Emacs can solve this problem,
because Emacs doesn't understand the significance of each font.

Which problem is that?  The 2 questions you asked or something else?

What do you mean by "min line-width" here?

Did you try to set the line-height text property on the newline of
each line?
