Dec 28 (Reuters) - Copper prices in China hit a one-month high on Tuesday, helped by easing worries over the impact of the Omicron variant and hopes of continued policy support for economic growth in the world's top metals consumer.

The most-traded February copper contract on the Shanghai Futures Exchange ended daytime trading 1% higher at 70,450 yuan ($11,059.83) a tonne. It had touched 70,870 yuan earlier in the day, the highest since Nov. 26.

"Risk sentiment improved as early data showed that the new coronavirus variant may cause milder symptoms," analysts at Huatai Futures said in a note.

Stock and oil prices also advanced as some European countries refrained from imposing tough mobility restrictions, with the British government in particular awaiting more evidence on whether its health service can cope with high infection rates.

The London Metal Exchange remained shut for a public holiday on Tuesday.
