HONG KONG, Nov 30 (Reuters) - China and Hong Kong shares extended gains on Wednesday as market participants cheered an easing of COVID-19 measures in Guangzhou city and auto stocks surged on potential favourable policies.
Southern Guangzhou city relaxed COVID prevention rules in multiple districts including Fanyu, Tianhe, Conghua, Huadu and Liwan, boosting investor sentiment dampened by worse-than-expected China factory and service activity data.

"Nonetheless, the market sentiment is improving as investors look through the weak economic data in the short term. The key question on investors' minds is how long this reopening process will take."
Auto stocks led the gains on strong October sales figures despite the COVID impact. Reports of an industry move to suggest the government extend its purchase-tax waiver for ICE vehicles also lifted sentiment.
