* China’s exports of alumina fell 37.9 pct to 285,696 tonnes in November from October’s 460,072 tonnes, according to data released by the General Administration of Customs on Sunday.
* China has this year been shipping unusually high volumes of alumina, a substance used to make aluminium, amid global market tightness and a favourable price arbitrage.
* Exports so far this year have now exceeded 1 million tonnes.
* International alumina prices fell by 16.8 percent in November, reducing the incentive for Chinese producers to export. (Reporting By Tom Daly, Yilei Sun and Norihiko Shirouzu in Beijing; editing by Darren Schuettler)
