BEIJING - A senior official of the Communist Party of China (CPC) has called for a new campaign designed to boost CPC-people ties to be carried out properly in order to bring a "big improvement" of officials' work styles.

Liu Yunshan, head of a leading group formed by the CPC Central Committee to direct the campaign, made the remarks at a meeting held on Tuesday, the same day the year-long campaign was officially launched, according to an official statement issued Wednesday.

Undesirable work styles such as formalism, bureaucratism, hedonism and extravagance take different forms in different departments and localities, Liu said.

"(Each department or organization) should act according to its own actual situation and strive to spot problems, analyze their causes and find specific solutions," he said.

Whenever a problem can be solved earlier it should be done, so as to bring "a big improvement in officials' work style," according to Liu, who is also a member of the Standing Committee of the Political Bureau of the CPC Central Committee.

Liu urged local authorities to learn from a speech given by President Xi Jinping during a Tuesday meeting that marked the start of the campaign.

Xi described the campaign as a "thorough cleanup" of undesirable work styles.
