* Dollar up across the board on safe-haven bid
* Stocks fall, Treasuries gain ahead of Fed statement
* Crude, copper down as China imports slow in July

NEW YORK, Aug 10 (Reuters) - World stocks slumped and the dollar rose broadly on Tuesday on weak Chinese data and uncertainty over whether the U.S. Federal Reserve will take aggressive action to help the faltering economic recovery.
U.S. Treasury prices rose in a flight to quality ahead of the central bank decision, and commodity prices fell after data showed Chinese imports slowed in July.
The euro extended losses against the dollar to trade more than 1 percent lower as the greenback was boosted by a growing view the Fed's Federal Open Market Committee was unlikely to announce any aggressive easing measures.
The Fed is not expected to shift interest rates from the current level near zero, but is seen acknowledging recent economic weakness and signal a willingness to take more steps to support the softening recovery. The Fed will issue a statement at about 2:15 p.m. EDT (1815 GMT).
Investors began to reassess their expectations overnight. Some see the Fed taking minor steps such as reinvesting funds to maintain its balance sheet, while others say it will adopt a wait-and-see attitude until at least next month. For details, see [
