* Federal Reserve policy meeting in focus
* World stocks down but Europe has mild gains
* Wall Street set for flat start
* Dollar slips

LONDON, Aug 12 (Reuters) - Uncertainty about the Federal Reserve's view on the U.S. economy and another sharp fall in Chinese stocks weighed on global equities on Wednesday although Europe managed mild gains
Wall Street looked set for a flat to positive start and the dollar slipped against major currencies.
The Fed finishes a two-day policy meeting later on Wednesday, with expectations that it will leave benchmark interest rates near zero and let a $300 billion quantitative easing programme to buy Treasury securities expire on schedule in September as economic gloom lifts.
But after a report showing U.S. firms continue to cut inventories as they lack confidence in the economy, analysts expect the Fed will try to dampen speculation about higher interest rates while still supporting hopes that the makings of a recovery are at hand. Its statement is due at about 1815 GMT.
The Bank of England, meanwhile, said inflation will be well below the 2 percent target in two years if interest rates rise in the first quarter, suggesting markets have been pricing in rate increases too early. [

"World share markets have been moving in tandem for a while and there's growing concern that many have been overbought, which may lead to a bit of adjustment after all the gains," said Masayoshi Okamoto, head of dealing at Jujiya Securities in Tokyo.
One area of concern was China, where Shanghai's bourse <

DOLLAR SLIPS
The dollar steadied slipped against other major currencies before the Fed's verdict.
"Unless the Fed delivers a markedly upbeat statement that can bring forward tightening expectations, or starts to detail exit strategy tools, it looks as though the dollar will struggle to build on recent gains," said Chris Turner, head of FX strategy at ING.
The euro was up 0.1 percent to $1.4163 after dipping to a 1-1/2 week low against the dollar of $1.4087 <EUR=>. The dollar was down 0.2 percent at 95.75 yen after falling as low as 95.13 yen <JPY=>.
Euro zone government bonds were higher. Two-year yields <EU2YT=RR> were 4 basis points lower at 1.448 percent, with 10-year yields <EU10YT=RR> off 3 basis points at 3.449 percent.
