Caixin/S&P's composite PMI, which includes both manufacturing and services activity, rose to 48.3 in December from 47.0 in the previous month, remaining in contractionary territory for the fourth straight month.
The Caixin PMI is compiled by S&P Global based on responses to questions sent to purchasing managers in China.
