His social media post came hours after US Treasury Secretary Scott Bessent said trade talks with China aimed at putting to bed sky-high mutual tariffs -- currently suspended -- were "a bit stalled".

The development risks renewed trade pugilism between the world's two biggest economies.

"If President Trump does slap tariffs back on Chinese imports to the US... we may see demand for US assets, and the dollar, severely impaired by a chaotic and undiplomatic approach to trade policy," said Kathleen Brooks, research director at XTB.

New York shares dipped into the red, as did Asia's markets, though their close came before Trump posted his message. Paris also closed down while London and Frankfurt ended higher.

The movements were relatively limited, with investors appearing to be largely inured to Trump's now-familiar cycle of making dramatic trade threats then retreating.

Economic data informed a lot of the trades.

A key US inflation indicator released Friday showed April core price rises had slowed to 2.1 percent, milder than expected.

Analysts warned that the fuller inflationary effects in the United States of Trump's tariffs were yet to come and could cause the Fed to maintain its watch-and-wait stance.

"The true weight of these policies is likely to emerge more fully in the months ahead," said FOREX.com market analyst Fawad Razaqzada.

Investors were also assessing the impact of a US court ruling that invalidated most of Trump's sweeping tariffs -- though an appeals court suspended that order and the White House vowed the tariffs goal would be pursued one way or another.

"The ruling didn't mean that all tariffs were off the table, it could affect trade negotiations going forward," noted David Morrison, senior market analyst at Trade Nation, adding that it only injected "ongoing uncertainty surrounding trade policy".

Stephen Innes, of SPI Asset Management, said the result was "a legal limbo... the kind that keeps traders awake at night".

In the eurozone, interest rates were in focus after official data showed inflation hovering around the European Central Bank's two-percent target.

Consumer prices in top EU economy Germany showed a 2.1 percent rise in May -- the same as the previous month -- while they fell in Spain, to 1.9 percent, and in Italy, to 1.7 percent.

The ECB looks set to lower interest rates again on Thursday.

The dollar gained against major currencies, while oil prices were down ahead of a Saturday meeting of eight key OPEC+ members to decide production quotas for July, with some analysts saying the cartel could make a larger-than-expected supply hike.
