BEIJING, Dec 30 (Reuters) - China's factory activity is expected to have extended declines in December, a Reuters poll showed on Friday, as the end of the country's "zero-COVID" policy and rising infections began to affect production lines.
An index reading below the 50-mark indicates contraction in activity on a monthly basis and a reading above indicates expansion.
The official manufacturing PMI, which largely focuses on big and state-owned firms, and its survey for the services sector, will be released on Saturday.
The private sector Caixin manufacturing PMI, which centres more on small firms and coastal regions, will be published on Jan. 3.
Analysts polled by Reuters expect a headline reading of 48.8, down from 49.4 in November.
