(Reuters) - Gold prices rose for a third straight session on Tuesday as the dollar languished near a five-week low, as investors eyed rising tensions between Russia and the West even as a U.S.-China trade spat appeared to ease.
Spot gold was up 0.16 percent at $1,355.19 per ounce at 0739 GMT, after touching $1,356.66 earlier in the session, its highest since Feb. 16.
U.S. gold futures for April delivery were flat at $1,355 per ounce.
"Gold prices continue to ratchet higher as the U.S. dollar weakens despite equity markets rebounding on easing concerns about the likelihood of a trade war between China and USA," Stephen Innes, APAC trading head at OANDA, said in a note.
"Realistically there are plentitudes of market turmoil in the making that continue to make gold the go-to place to hedge risk."
