Sept 23 (Reuters) - Gold prices edged higher on Wednesday, supported by renewed U.S.-China tensions and concerns over economic recovery, but a robust dollar capped gains. FUNDAMENTALS * Spot gold rose 0.2% to $1,902.04 per ounce by 0100 GMT. * U.S. gold futures eased 0.1% to $1,905.60. * The dollar index hit an eight-week peak. A firmer dollar makes bullion more expensive for holders of other currencies. * U.S. President Donald Trump told the United Nations General Assembly on Tuesday that China must be held accountable for having "unleashed" COVID-19 on the world, prompting Beijing to accuse him of "lies" and abusing the U.N. platform to provoke confrontation. * Top U.S. economic policymakers opened the door on Tuesday to further aid for small businesses hit by the coronavirus-triggered recession, but differed over how broad it might extend and the manner in which it should be delivered. * Meanwhile, Chicago Fed President Charles Evans said the central bank still needed to discuss its new average inflation target but that it "could start raising rates before we start averaging 2%." * Low interest rates tend to support gold, which is considered a hedge against inflation and currency depreciation. * The UK has imposed fresh set of curbs to tackle a second wave of COVID-19, with new restrictions lasting probably six months. * Holdings in SPDR Gold Trust , the world's largest gold-backed exchange-traded fund, fell 0.05% to 1,278.23 tonnes on Tuesday. * Silver fell 0.6% to $24.26 per ounce, platinum rose 0.3% to $869.64 and palladium slipped 0.8% to $2,203.15.
