NEW YORK, July 11 (Reuters) - Stocks fell and metals prices slumped on Wednesday as U.S. threats of tariffs on an additional $200 billion worth of Chinese goods pushed the world's two biggest economies closer to a full-scale trade war.
U.S. President Donald Trump's threat overnight of 10 percent tariffs on another $200 billion of Chinese goods dampened hopes that Washington will eventually step back from the escalating row. clock now starts ticking on a two-month period of public comment before the levies are imposed. Trump has said he may ultimately target more than $500 billion worth of Chinese goods - roughly the total amount of U.S. imports from China last year.
U.S. stocks fell on the news but were not hit nearly as hard as in Shanghai, where shares .SSEC closed 1.78 percent lower and the yuan CNY= weakening toward last week's 11-month lows.
"Unfortunately the markets haven't come to grips with the current levels of trade policies and tariffs," said Art Hogan, chief market strategist at B. Riley FBR in New York.
"Concerns over trade and trade wars are really having an adverse effect, less so on the U.S. markets than the international markets, but it is certainly taking a bite." Dow Jones Industrial Average .DJI fell 179.96 points, or 0.72 percent, to 24,739.7, the S&P 500 .SPX lost 18.12 points, or 0.65 percent, to 2,775.72 and the Nasdaq Composite .IXIC dropped 47.90 points, or 0.62 percent, to 7,711.30.
In Europe, shares extended losses after Trump kicked off a NATO summit in Brussels by accusing Germany of being a "captive" of Russia. .EU
Australia's dollar, often seen as a proxy for China's economic fortunes due to Australian raw materials exported there, was 0.83 percent lower. AUD=D4 /FRX

Morgan Stanley (NYSE:MS) told clients in a research note on Wednesday that the trade conflict is "creating earnings noise and eroding gains from fiscal stimulus, which we think was already in the price."
