Japan, the US and South Korea have agreed on closer cooperation to strengthen and secure supply chains for semiconductors, key minerals and batteries.
Ministers from the three countries held an inaugural meeting on the issues in Washington on Wednesday.
Japanese Industry Minister Saito Ken, US Commerce Secretary Gina Raimondo and South Korean Industry Minister Ahn Duk-geun attended.
The ministers expressed concerns about use of tariffs and export caps that can disrupt supply chains.
This follows moves by China last year to restrict exports of materials used to make semiconductors, including gallium-based compounds.
The ministers agreed to hold meetings each year to build on the supply-chain cooperation strategy.
