European stocks track Wall street gains ahead of fed

European shares rose in early trade on Wednesday, mirroring a rally on Wall Street sparked by a report that shifted investor expectations for the U.S. Federal Reserve's policy statement due later in the day, Reuters reported.
At 0745 GMT, the FTSEurofirst 300 index of top European shares was up 0.4 percent at 1,384.83 points, after hitting a two-week low in the previous session.
British equities underperformed, with the FTSE 100 up 0.2 percent, as investors remained cautious ahead of Scotland's referendum on independence on Thursday. Three different opinion polls showed Scottish supporters of staying in the United Kingdom were 4 percentage points ahead of secessionists.
Resource-related shares gained ground, with ArcelorMittal up 1.4 percent and Anglo American 1 percent higher.
Media reports said China's central bank was injecting a combined 500 billion yuan ($81.35 billion) of liquidity into the country's top banks, a sign that authorities are stepping up efforts to shore up a faltering economy. That would potentially boost Chinese demand for commodities.
