How to make svn diff show remote changes?

Question

For Example, when I type

svn st --show-updates 

I get

    *   1648648   project/file1

so I know that file1 has changed.

I don't want to update just find out what has changed. When I type

svn diff project/file1

it shows nothing because the file has no local changes.
