query_posts with pagination not working

I am trying to make pagination work with the following code but no luck:

$page = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
    'cat' => '5',
    'post_type' => 'post',
    'posts_per_page' => 6,
    'paged' => $page,
);

query_posts($args);

while(have_posts()) {
    the_post(); ?>
    <div class="project_item">
        <div class="dotted">
            <hr />
        </div>
        <div class="project_thumb"><a href="<?php echo get_permalink(); ?>"><img src="<?php getCustomField('news_thumbnail'); ?>" /></a></div>
        <div class="project_entry"><h4><a href="<?php echo get_permalink(); ?>"><?php getCustomField('news_title'); ?></a></h4>
            <?php getCustomField('news_excerpt'); ?>
            <a href="<?php echo get_permalink(); ?>" class="readmore">Read more..</a>
        </div>
    </div>
<?php }

wp_reset_query();  // Restore global post data
