NEW YORK (Reuters) - Stocks around the world fell on Thursday and the U.S. dollar slipped from a peak as investors flocked to bonds on worries about a U.S.-China trade war.

A weaker-than-expected U.S. economic indicator also hit confidence.

The dollar fell from an 11-month high against a basket of major currencies after the Philadelphia Federal Reserve’s gauge of U.S. Mid-Atlantic business activity fell to a near 1-1/2 year low.

U.S. equity investors sold shares as they got some specific indications on the potential impact of President Donald Trump's trade tariff stand-off with China. German carmaker Daimler DAIGn.DE cut its earnings forecast late on Wednesday, saying tariffs on cars sent from the United States to China would hurt Mercedes-Benz car sales.

Also of concern was the U.S. immigration crisis after Trump backed off an unpopular hardline policy that had led to children being separated from their parents when they crossed illegally into the United States from Mexico.

“The headlines seem to be motivating the market. The immigration issue and trade,” said Phil Blancato, chief executive of Ladenburg Thalmann Asset Management in New York. “It leads to a lack of confidence in the administration’s ability to push its economic agenda forward.”

Emerging market stocks lost 1.20 percent.

Argentina's MSCI stock index .MIAR00000PUS, however, rose 5.2 percent, its biggest one-day percentage gain since October.

Index provider MSCI said late on Wednesday it would reclassify Argentina and Saudi Arabia as emerging market countries next year, broadening the investor base for both countries.

The Japanese yen strengthened 0.34 percent versus the greenback at 109.99 per dollar.

Global benchmark Brent crude fell more than 2 percent ahead of a meeting of the Organization of the Petroleum Exporting Countries, where producers were expected to boost output to stabilize prices. But OPEC was struggling to agree on raising output, with Saudi Arabia warning of supply shortages and price rallies and Iran holding out against a deal.

In the latest trades, U.S. crude CLcv1 rose 0.09 percent to $65.77 per barrel and Brent LCOcv1 was last at $73.16, down 2.11 percent on the day.
