Profit more than halved at Hindalco's aluminum upstream segment, which includes bauxite and coal.

Glencore has deposited more than 100,000 tonnes of aluminum in LME registered warehouses in South Korea.

When the UK imposed tariffs on Russian metal last year, the LME responded by banning new deliveries of Russian metal into its warehouses in the UK.

The move against aluminum also continues efforts by the US and European Union to blunt Russia’s role as global commodities powerhouse.

The US metals producer had reached a deal with workers in December 2021 to end primary aluminum production at San Ciprian.

Aluminum, and items made from the metal, now join cotton, tomatoes and polysilicon, in coming under scrutiny over links to forced labor in Xinjiang.

Analysts are cautious that China's recovery may not live up to bullish expectations and that prices have got ahead of themselves.

A build-up of Russian metal is likely to raise concern in the market that benchmark LME prices will weaken.
