LONDON, April 4 (Reuters) - The main global stock market

index fell into 'correction' territory on Friday as China hit

back at the sweeping trade tariffs announced by U.S. President

Donald Trump this week.

MSCI's All Country World Index, which includes 2,645

companies, was down more than 1% on day the after Beijing had

said it would put additional tariffs of 34% on all U.S. goods

and slap curbs on exports of some key rare earths.

The drop was expected to increase when Wall Street trading

resumes, futures indicated. But the falls already meant it had

lost 10% since hitting a record high in February, a threshold

traditionally classed as a 'correction' by market analysts.
