SHANGHAI: China stocks started the week on a firm note, as investors cheered Beijing's continued policy support to shore up its economy hurt by the coronavirus crisis.

China will maintain policy support for its economic recovery, avoiding a sudden shift in policy, to help keep economic growth within a reasonable range in 2021, the Xinhua news agency said on Friday, after a meeting of top leaders ended.

The annual Central Economic Work Conference, a gathering of top leaders and policymakers to chart the economy's course in 2021, is being watched by investors amid speculation that Beijing would make policy changes amid accelerating growth, following a virus-induced slump earlier this year.

"Setting the tone for stable and continued policies lays a foundation for a market rally, providing opportunities for both growth and cyclical firms," Southwest Securities analysts said in a note.

Bucking the broad strength, surveillance camera maker Hikvision and top chipmaker SMIC eased on index exclusion and US blacklisting.

SMIC said on Sunday that being put on a US trade blacklist would pose a significant adverse impact to its research and development in its 10-nanometer and more advanced chip technology.
