China will continue its clean governance and anti-corruption campaign next year and won't allow any opportunity for officials to slip back into undesirable work styles, senior leaders agreed on Wednesday.

This year saw progress and improved public confidence in the campaign to strictly govern the Communist Party of China and punish violators, according to a statement released after a meeting of the Political Bureau of the CPC Central Committee - a top decision-making body chaired by President Xi Jinping.

The violators included Zhou Yongkang and Ling Jihua, two former senior Party officials, the statement said.
