1st Q: are those "muti-shaped" tubes Alu-alloy or steel alloy (use any magnet)
Beyond that chances are there's no Country of Origin sticker but have you looked EVERYwhere for one?
This is a style from Y2K and later, might have been built (or just had final assembly) in Italy or another EU country but just as likely has Asian origins, most likely Taiwan (but possibly PRC)
some more detail pix of the frame (DOs, bridges, seat cluster, is that a "wishbone" rear?) are helpful; the fork is clearly CF but head tube is small looking so is this a 1" HS (rather than more typical 1.125")?
The Coppi brand by this timeframe wouldn't have much or any connection with the contract-builders of old like Fiorelli, but maybe wasn't an outright buy-out by some nameless corporate holding company who off-shored the whole enterprise...maybe

NOTE: I recall there were some similar-looking frames that used a multi-shaped Columbus tubing and sold under several brand names, including well-known "Italian brands" that after long research by curious C&Vers was decided to be akin to what Bianchi used for a couple models and was something like Thron (but multi-shaped).
Howerver if this "Coppi" is aluminum with a CF rear then this info is pointless "nothing to see, here, people...move on..."
