How to rename the Category Metabox title

How do I rename the Category Metabox title? This doesn’t work…

add_action( 'add_meta_boxes', 'change_cat_meta_box', 0 );
function change_cat_meta_box() {
global $wp_meta_boxes;
unset( $wp_meta_boxes['post']['side']['core']['categorydiv'] );
add_meta_box('categorydiv',
__('Country'),
'post_categories_meta_box',
'post',
'side',
'low');
}
