Indonesian business has criticised the “unfair” exclusion of the country’s critical minerals from a huge package of US subsidies for green technology as it seeks to assuage Washington’s concerns about Chinese dominance of its sprawling resources sector.

Arsjad Rasjid, chair of the Indonesian Chamber of Commerce and Industry (Kadin), which has close ties to the government, said Indonesia could play a crucial role in fulfilling US demand for electric vehicles and batteries. The country has the world’s largest reserves of nickel, a vital material for EV battery production.

The US government is expected in the coming weeks to publish guidance on how battery and EV makers can qualify for tax credits under the Inflation Reduction Act, a landmark climate bill passed last year which includes $370bn in subsidies for clean energy technology.
