China has established a new state-backed mining investment entity, Guangyan International Investment, to tighten oversight of its overseas mineral supply chains, Bloomberg reported, citing sources.

The company, also known by its English name Vast Rock International Investment, will operate within a broader initiative led by China’s National Development and Reform Commission (NDRC), the country’s economic planning body.

Guangyan is set to provide a range of services, from direct equity investment to advisory support covering compliance, risk management and market conditions.

According to the sources, China is looking to standardise procedures for international metals transactions to strengthen oversight, with miners being encouraged to take on partners rather than pursue full ownership of projects – a shift driven partly by rising costs and heightened political risk.

Engagement with Guangyan will not be compulsory, and larger firms may be reluctant to share information or hand over risk assessments, the sources noted.

They likened this dynamic to China Mineral Resources Group, which has been working to consolidate China’s control over iron ore procurement and bolster the steel industry’s negotiating power.

Even so, some domestic firms are being urged to submit their plans for review, the sources added.

Chinese firms hold stakes in copper and cobalt operations in the Democratic Republic of Congo, along with major iron ore ventures and Indonesia’s nickel sector.

This development comes as resource-rich nations tighten conditions around extraction, while the US and EU work to establish alternative supply chains.

Congo brought in export controls on cobalt last year, and Guinea has discussed restricting bauxite shipments while pushing for companies in the Simandou iron ore project to construct facilities for producing iron pellets or steel.

Zimbabwe, meanwhile, has warned producers that failure to invest further in refining could result in an export ban on lithium concentrate – prompting the Chinese embassy in Harare to urge companies to bolster risk prevention measures, Bloomberg reported.
