China has quietly almost doubled its gold reserves to become the world’s fifth-biggest holder of the precious metal, it emerged on Friday, in a move that signals the revival of bullion after years of fading importance.

Gold rose to a three-week high of more than $910 an ounce after Hu Xiaolian, head of the secretive State Administration of Foreign Exchange, which manages the country’s $1,954bn in foreign exchange reserves, revealed China had 1,054 tonnes of gold, up from 600 tonnes in 2003.
