"As traders put geopolitical and trade risk in the rear-view mirror for the time being, how the dollar flourishes and wilts will be the primary driver of near-term gold sentiment," said Stephen Innes, APAC trading head at OANDA.
The dollar index, which measures the greenback against a basket of currencies, was up 0.1 per cent at 90.816, just below 91.076 hit in the previous session, its strongest level since January 12.
"I think that the downward trend (in gold prices) will continue for the next few days..." ahead of a meeting between leaders of North Korea and the South, said Ji Ming, chief analyst at Shandong Gold Group.
North Korean leader Kim Jong Un is due to hold a summit with South Korean President Moon Jae-In on Friday, and is expected to meet with US President Donald Trump in late May or early June.
Mr Trump said on Tuesday the United States would likely reach a trade agreement with China and that officials from both sides would sit down for negotiations in a few days.
"When the equity walls come crumbling down, gold offers the best support," Mr Innes said.
Gold is often seen as an alternative investment during times of political and financial uncertainty.
