June 6 (Reuters) - Copper prices in Shanghai climbed to their highest in nearly four weeks on hopes of stimulus measures from top metals consumer China and amid a drop in inventory.

The most-traded July copper contract on the Shanghai Futures Exchange climbed as much as 1.3% to 66,870 yuan ($9,405.99) a tonne, the highest level since May 11, before easing to 66,780 yuan a tonne at the midday break, up 1.2%.

Three-month copper on the London Metal Exchange advanced 0.1% to $8,347 a tonne by 0433 GMT, while nickel increased 0.6% to $21,020 a tonne, zinc rose 1.1% to $2,314.50 a tonne.

China will likely further cut banks' reserve ratio and interest rates in the second half of this year to support the economy, the China Securities Journal reported, citing policy advisors and economists.

Investors also hoped that Beijing would roll out supportive measures soon to bolster the embattled property sector, which consumes a vast amount of metals.

Meanwhile, LME on-warrant copper inventory dropped 19.9% on Friday, the biggest daily slump since October 2022, latest data showed.

SHFE copper inventories were at 86,648 tonnes, 66% lower than late February.

LME lead was up 0.3% at $2,033.50 a tonne, tin increased 0.7% to $25,730 a tonne while aluminium fell 0.4% to $2,236 a tonne.

SHFE nickel rose 0.3% to 160,130 yuan a tonne, zinc increased 1.2% to 19,465 yuan a tonne, tin edged up 0.2% at 209,380 yuan a tonne, while aluminium fell 0.7% to 18,150 yuan a tonne.
