Dec 31 (Reuters) - Copper prices eased on Tuesday but

were on track for a second consecutive yearly gain, while the

red metal's outlook for next year hinges on China's economic

recovery and Donald Trump's policies.

Three-month copper on the London Metal Exchange (LME) fell

0.4% at $8,872.50 per metric ton by 1010 GMT but gained 3.7% for

the year.

"Supply setbacks at global mines contributed to a tightening

in global copper market... On the demand side, industrial

recovery in key economies alongside demand from the green energy

transition helped support prices," said Aneeka Gupta, director

of macroeconomic research at WisdomTree.

In May, copper prices scaled a historic high of $11,104.50,

fuelled by a fund-buying frenzy. But, since then, prices have

fallen about 20% - pressured by a strong dollar, import tariff

threats and persistent doubts over China's recovery.

China, the biggest commodity consumer, has struggled to

recover amid weak consumption and a protracted property crisis.

However, policymakers hope a recent blitz of fiscal and monetary

measures will spark a turnaround.

Meanwhile, Trump threatened tariffs in excess of 60% on

Chinese goods during his campaign.

"Uncertainty around the scope and fallout of any possible

trade wars under the incoming Trump administration could cast a

cloud over industrial metals demand," said Tim Waterer, chief

market analyst at KCM Trade.

"If 2025 sees a continuation of the Chinese economic

malaise, this could be a headwind for the copper price."

LME aluminium dipped 0.1% at $2,548 a ton and rose

7% this year, aided by a raw material shortage. Prices of

alumina, the main ingredient for making primary aluminium,

rallied this year due to supply disruptions.

LME zinc dropped 0.3% to $3,011.50 and rose 13.3%

for the year. Tin fell 0.8% to $29,050 and registered an

annual gain of 14.4%.

LME nickel lost 0.3% to $15,360, while lead

was 0.1% higher at $1,949. The metals chalked up annual losses

of 7.5% and 5.8%, respectively.
