Gold edged higher on Wednesday, supported by a weaker dollar after mild US inflation data cemented bets for an interest rate cut in September, while investors focused on this week's US-Russia talks over the war in Ukraine. Spot gold was up 0.2% at $3,351.46 per ounce, as of 02:39 GMT. US gold futures for December delivery gained 0.1% to $3,401.60.
