Senior leader Liu Yunshan on Saturday called for persistent implementation of the Party's "mass line campaign," as the second phase of the campaign nears the end.

The campaign is in its key stage, and more strength should be exerted with its approaching to the end, according to Liu, a Standing Committee member of the Communist Party of China (CPC) Central Committee Political Bureau.

The campaign was launched in June last year to make government more accessible to the public while cleaning up officials' undesirable work styles.

The second phase of the campaign is scheduled from January to September 2014, targeting more low-level departments and leaderships, while the first phase focused on central and provincial-level departments.

Various levels of Party committees should reinforce the implementation of the campaign to ensure that it will not end in shouting slogans, Liu said.

He asked authorities to really solve the specific problems resented by the people, such as the issue of "naked officials," or those whose spouses and children have all emigrated overseas.

Liu also asked officials and Party members to study President Xi Jinping's remarks on creating a sound environment for political career and take the lead in promoting a clean "political eco-system."
