Senior Chinese leaders on Thursday made remarks on core socialist values and development in panel discussions with deputies attending the annual session of the National People's Congress (NPC), the country's top legislature.

Liu Yunshan, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, participated in the discussion with deputies from northwest China's Shaanxi Province.

He called for long-term efforts to promote cultural and ethical progress and bolster core socialist values.

Liu also urged enhancing social awareness of rule of law in which the whole society should believe.

Wang Qishan, head of the CPC Central Commission for Discipline Inspection, told deputies from Tibet Autonomous Region that Party members should always remember the CPC's fine tradition and work styles and stick to the principle of serving the people wholeheartedly.

Correcting undesirable work styles such as formalism, bureaucratism, hedonism and extravagance was a war that the Party could not afford to lose, he said.

Disciplines should be strictly observed through long-term mechanisms so that officials dare not commit corruption, he said.

During a panel discission with deputies from southwest China's Yunnan Province, Vice Premier Zhang Gaoli hailed achievements the province had made.

He encouraged the local government to gear up efforts to participate in the Belt and Road initiatives, and the development of Yangtze River Economic Belt.

The province should also take a leading role in promoting ethnic solidarity and ecological civilization and better cooperate with economies in south Asia and southeast Asia, Zhang said.
