Jan 27 (Reuters) - Gold rose on Tuesday, after breaking through the $5,100 mark for the first time in the previous session, as geopolitical uncertainty underpinned safe-haven demand, while silver also hovered near all-time highs.

Spot gold XAU= climbed 0.9% to $5,060.36 per ounce, as of 0507 GMT, after scaling a record $5,110.50 on Monday.

U.S. gold futures GCcv1 for February delivery eased 0.5% to $5,056.90 per ounce.

"Trump's disruptive policy approach this year is playing into the hands of precious metals as a defensive play. The threats of higher tariffs to Canada and South Korea are doing enough to keep gold a safe-haven choice," said Tim Waterer, KCM Trade's chief market analyst.

Escalating trade tensions, U.S. President Donald Trump said on Monday he would raise tariffs on South Korean auto, lumber, and pharmaceutical imports to 25%, while criticizing Seoul for failing to enact a trade deal with Washington.

This was after he threatened tariffs on Canada in the backdrop of a thawing relationship between the two countries, following Canadian Prime Minister Mark Carney's visit to China earlier this month.

China's Zijin Gold 2259.HK will buy Canada's Allied Gold AAUC.TO for about C$5.5 billion ($4.02 billion) in cash, amid record high prices for gold. Gold's unprecedented rally has boosted miners' margins and cash flows, fuelling consolidation.

"The intervention from U.S. and Japanese officials to steady the yen has dented the dollar and has been a boon for the gold price," KCM's Waterer added.

A looming U.S. government shutdown and Trump's erratic policymaking also pressured the greenback, making the dollar-priced gold cheaper for overseas consumers. USD/
