Combination of not using commands and options correctly. Does your scott user have dba granted to him? If not, then full what? Why are you using old export and import in 11g? No one here has any idea what your export session's connection is pointing to.

Currently I have tables like country, city, channel, client, client_data etc..
But none of these table exported?
Because obviously they do not exist in the scott schema you connected to in the export session.
