Chinese investors are snapping up gold bars and coins, buying more than ever before in the first quarter of 2011 and overtaking Indian buyers as the world's biggest purchasers of the metal.

China's investment demand for gold more than doubled to 90.9 metric tons in the first three months of the year, outpacing India's modest rise to 85.6 tons, the World Gold Council said in its quarterly report on Thursday. China now accounts for 25% of gold investment demand, compared with India's 23%.

The report underscores the rising appetite for gold among the growing middle-class in China. Fears of the country's soaring inflation, as well as a search for new investments, is luring investors to gold, and marketing of the precious metal has also increased in recent months.

"I think people will be surprised by the strength in the Chinese demand, but we think this is a trend that is set to continue," said Eily Ong, an investment research manager at the gold council.
