Lots of copyright doctrines are more restrictive than the US. Most notably, a lot of jurisdictions don't have a concept of fair use nearly as broad as the US concept.
Also, the US uses trade treaties to cajole other countries into adopting very restrictive copyright doctrines. It's more common than you'd think.
The lack of fair use is a problem in non-US jurisdictions.
However, I'm not aware of anywhere where copyright lasts longer than the US (except in special cases like Peter Pan[1], even if that is really just perpetual rights to royalties from performance[2]).
Edit: Just noticed that [2] says copyright in Mexico is actually longer than in the US, but I'm not aware of the specifics of how it works.
Honduras has life + 75 years. Also some countries provide circumstantial extensions e.g. France's copyright is life + 70, but if the author is "Mort pour la France" (died for France, which is usually applied to service members but may also apply to civilians) it's life + 80.
A few countries did that, but those extensions were mostly predicated on a 50 years copyright (the "morts pour la france" extension also is, it's 30 years tacked onto the original 50). When copyright got normalised to 70 by EU rules (or separately extended before EU or EU entry), these extensions became moot in EU countries. IIRC Russia is the only country where war copyright extensions still apply, as a 4 years extension was specifically added when they rewrote their copyright laws in 1993.
