Gold edged lower on Monday after three weeks of gains as investors awaited the results from a key Federal Reserve policy meeting this week for guidance on when the central bank would begin to scale back its stimulus.
Investors were also digesting the launch of China's first gold-backed exchange traded funds (ETFs), which opened to lacklustre performance on the Shanghai Stock Exchange.
Spot gold fell 0.5 percent to $1,326.91 an ounce by 0331 GMT, after gaining 9 percent over the last three weeks. US gold gained about $5 to $1,326.90.

China's two new gold-backed ETFs fell on their first day of trading. HuaAn Gold ETF fell 0.5 percent, while Guotai Gold ETF was down 0.6 percent.

The launch and trading of the ETFs are being closely watched to see if local investors' appetite for paper gold can match their hunger for physical bullion.
China is set to overtake India as the world's biggest consumer of gold this year, according to the World Gold Council.
