Cause:
The error is expected behavior because of missing dependent container table of the mview.

All mviews are created along with a container table during initial phase. During export/import, the dependent container table should also be export/imported in database.
Solution:
Verify the container table.
SQL> col OWNER for a20
SQL> SELECT owner,object_name, object_type FROM dba_objects WHERE object_name = 'MVREMOTE';
OWNER OBJECT_NAME OBJECT_TYPE

Export both container and its mview pair.
