What does で means in this sentence? [duplicate]

Question

• 中国人で日本語が話せる方

I think it's traduction would be:

• Chinese people who can speak Japanese

But I have searched for references of this で usage yet I haven't find anything.

Answer 1

Rather than a particle, this で is the te-form of だ.

So the meaning of the relative clause attached to 方 is: “is a Chinese person and can speak Japanese”.

You can compare it to the で you put after na-adjectives (example also from imabi):

6. 東京は賑やかで面白い。
   Tōkyō wa nigiyaka de omoshiroi.
   Tokyo is lively and interesting.

Nouns and na-adjectives are not so different, after all.
