NEW YORK, March 20 (Reuters) - The global copper market turned into a production surplus of 34,000 tonnes in December, as weak refined usage in major consuming regions offset strong Chinese demand, data from the International Copper Study Group showed.
For full-year 2013, the market had a 193,000-tonne deficit, compared with a shortfall of 266,000 tonnes in the same period a year earlier, the ICSG said on Thursday.
On a seasonally adjusted basis, the market deficit was at 337,000 tonnes in December, the data showed.
In November, the global copper market deficit was at 129,000 tonnes, mostly due to demand for refined copper from top consumer China, ICSG data showed. [ID:L6N0LQ2PD]
