Gold futures on the COMEX division of the New York Mercantile Exchange settled above 1,200 U.S. dollars an ounce on Wednesday, as worries about trade negotiations and weakness in the dollar helped to boost the precious metal's investment appeal.

The most active gold contract for December delivery went up 2.2 dollars, or 0.18 percent, to close at 1,201.3 dollars per ounce.

Investors were worried about the unsettled tariff disputes, notably between the United States and its neighbor Canada. The outlook for emerging-market economies also has fostered a recent spate of anxiety on Wall Street.

The U.S. dollar index, which measures the buck against six rivals, went down 0.25 percent to 95.17 as of 1922 GMT.

Gold usually moves in opposite directions with the U.S. dollar, which means if the dollar goes weak, gold futures will rise as gold, priced in U.S. dollar, becomes less expensive for investors using other currencies.

As for other precious metals, silver for December delivery rose 4 cents, or 0.28 percent, to settle at 14.22 dollars per ounce. Platinum for October went up 6.1 dollars, or 0.78 percent, to close at 784.3 dollars per ounce. Enditem
