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 per cent to $1,326.91 an ounce by 0331 GMT, after gaining 9 per cent over the last three weeks.

US gold gained about $5 to $1,326.90.
    
"Gold is falling because of a lack of buying in Asia today," said one Hong Kong-based trader. "Everyone is waiting for the FOMC meeting and nonfarm payroll data this week before placing bets."
    
The Fed's Federal Open Market Committee (FOMC) begins a two-day meeting on Tuesday that could provide more clarity on when the US central bank would slow its $85 billion monthly bond purchases.

CHINA GOLD ETFs
    
China's two new gold-backed ETFs fell on their first day of trading. HuaAn Gold ETF fell 0.5 per cent, while Guotai Gold ETF was down 0.6 per cent.
    
The two funds raised a total of 1.6 billion yuan ($260.94 million) in their initial funding round, coming in well below expectations due to sliding gold prices and a recent credit-crunch scare.
    
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.
