On 14 May 2026, following an on-site inspection of mining operations in Mpanda Municipality and Nsimbo District Council in Tanzania's Katavi Region, Minister for Minerals Hon. Anthony Mavunde ordered the immediate suspension of all mining activities along the Mtisi River after inspectors found severe environmental degradation, absence of environmental management plans and NEMC permits, and foreign nationals operating machinery directly — in violation of the Mining Act Cap. 123 (R.E. 2019), which restricts foreign parties under Technical Support Agreements (TSAs) to advisory and technical-support roles only. Mavunde simultaneously directed all Resident Mining Offices nationwide to conduct a review of every TSA between local small-scale miners and foreign investors to verify legal compliance and ensure that agreements genuinely benefit Tanzanian citizens. Three large exploration licences recently revoked (linked to the 15 April 2026 mass-revocation) are to be reallocated to small-scale miners in Katavi Region under the Mining for a Brighter Tomorrow (MBT) framework.

President Peter Mutharika signed an executive order effective 21 October 2025 prohibiting the export of all raw, unprocessed minerals extracted in Malawi, covering uranium, rare earth elements, niobium, graphite, tantalum, bauxite, rutile, gold, copper, diamonds, heavy mineral sands, and all other minerals. Minerals that have been processed, refined, or value-added in Malawi are exempt. The order aligns with an announced National Mining Corporation to oversee mineral production and processing, and introduces fines and sanctions under Malawi law for violations.

The Saudi Council of Ministers adopted Resolution No. 269 on 11 October 2025, amending the Precious Metals and Gemstones Law to transfer all supervision, regulation, and licensing of precious-metals and gemstones manufacturing activities from the Ministry of Commerce (MoC) to the Ministry of Industry and Mineral Resources (MIM). The Ministry of Commerce retains authority over retail trade outlets and consumer-facing commercial activities. A six-month transition window — announced jointly by MoC and MIM on 16 October 2025 — requires all existing manufacturing practitioners to obtain an industrial licence through the "Sanai" platform; mandatory hallmarking, gemstone identification tagging, and consumer-documentation standards also take effect under the revised regulatory framework.

On 13 June 2025 the Ministry of Environment (MoE) and the Ministry of Mines and Energy (MME) jointly issued Interministerial Prakas No. 4838, amending Cambodia's environmental-impact-assessment classification rules for all construction and mining business projects. The Prakas mandates that all businesses conducting construction and mining projects — including artisanal enterprises (investment <USD 50,000) and small-scale enterprises (USD 50,000–250,000) previously outside the formal EIA architecture — must sign an environmental-protection letter and file it with the MME prior to commencing operations; no project may operate in areas designated off-limits by the MME. The first joint MoE+MME prakas on environmental compliance extends Cambodia's EIA architecture to the full spectrum of mining-sector operators, building on the Environmental and Natural Resources Code (June 2023) and Prakas No. 8 (February 2024, EIA consulting-firm accreditation standards), and cross-references Prakas No. 3591 (May 2025) for the investment-size classification thresholds.

Tanzania's Parliament passed the Written Laws (Miscellaneous Amendments) (No. 4) Act, 2024 (Bill No. 15 of 2024, published in the Special Gazette of the United Republic of Tanzania No. 34 Vol. 105 on 5 November 2024), which amends eight statutes including the Mining Act, Cap. 123. The mining-related provisions: (i) empower the Minister for Minerals, on recommendation from the Geological Survey of Tanzania (GST), to declare specific minerals as "critical" (essential to national economic, geopolitical, technology, or industrial use with limited or threatened supply) or "strategic" (mineral resources with diplomatic or defence importance) — the first Tanzanian statutory authority to do so; (ii) raise the minimum capital investment for a Mining Licence from USD 100,000 to USD 5,000,000 (a 50× hike pricing out junior explorers); (iii) authorise gemstone export following government-organised mineral auctions or international gem fairs while reaffirming the general beneficiation-in-Tanzania requirement on raw minerals and concentrates; (iv) require GST verification of mineral data on samples exported by mineral right holders; and (v) impose penalties for inaccurate or false mineral-data submissions. The Act establishes the gateway statutory authority for any future Tanzania critical- mineral export-control or stockpiling regime.

Angola's National Assembly enacted Law No. 8/24 on 3 July 2024, establishing graduated criminal penalties for illegal mining activity involving strategic minerals as defined in the Mining Code. The law creates imprisonment terms of 3–8 years for promoting or facilitating illegal operations, 2–8 years for installing unlicensed equipment or initiating unauthorised mining, and 2–6 years for transporting illegally-mined minerals, alongside a forfeiture mechanism enabling the State to seize instruments, products, and proceeds of crime. The measure closes a gap in Angola's prior Mining Code (Law 31/11 of 2011), which lacked standalone criminal-enforcement provisions for strategic-minerals protection. A companion instrument, Presidential Order No. 39/24 of 26 January 2024, established the National Observatory to Combat Illegal Exploitation of Strategic Mineral Resources as the coordinating enforcement body.

The CTRI transitional government of Gabon signed Décret n° 0276/PR/MM on 2 July 2024, establishing a dedicated legal regime for six "sovereign substances" (gold, silver, uranium, diamonds, gemstones, and rare earths) and granting the state an automatic 35% equity participation — free of all charges and non-dilutable — in any large-scale mine exploiting those materials. The decree also reserves the state an option to acquire a further 25% paid interest at market value, gives it pre-emption rights on title transfers, mandates in-country processing of extracted substances, and reserves small-scale mining titles exclusively for Gabonese nationals. Existing operators had one year from publication (until approximately 15 July 2025) to restructure their capital in compliance; the state vehicle channelling the free-carry stake is Équatoriale des Mines.

Rwanda's Parliament enacted Law n° 056/2024 of 26 June 2024 establishing a new tax on minerals, published in the Official Gazette special issue of 5 July 2024 and replacing the 2013 minerals-tax law that had used a three-category framework with a top rate of 6%. The 2024 statute restructures the mineral-tax regime into six categories (base metals, gemstones, platinum group metals, rare earth elements, energy minerals, gold) and applies differential rates between domestically processed minerals (royalty tax: 0.5%–3%) and raw-mineral exports (export tax: 0.5%–3%), explicitly favouring value-added processing. Notably the gold royalty falls from 6% to 0.5% and base-metal royalty from 4% to 3%. The law operates under separate tax-policy authority from the companion Mining Law n° 072/2024 enacted the same day and is the principal fiscal instrument underpinning Rwanda's 3T (tin/tantalum/tungsten) processing-hub strategy and broader value-addition agenda under the National Strategy for Transformation (NST1).

The Mines and Minerals Development (Amendment) Act, No. 29 of 2022 restructures Zambia's Mineral Royalty Tax (MRT) on copper from a flat rate to a four-band price-linked sliding scale, effective 1 January 2023. Under the new regime, copper royalties range from 4% of norm value when the LME price is below USD 4,000/tonne to 10% when prices exceed USD 7,000/tonne — at prevailing LME copper prices (~USD 9,000–10,000/t in 2024–2026), the effective rate is 10%, one of the highest copper royalty rates in the global copper belt. The Act also codifies flat royalty rates for other base metals (5%), gemstones (6%), and precious metals (6%), and abolishes the prior flat-rate copper royalty that applied regardless of commodity-cycle position, materially increasing state rent capture in high-price environments while preserving a 4% floor for project viability at low prices.

The Bureau of Industry and Security created Supplement No. 5 to 15 CFR Part 746, establishing a new licensing requirement for the export, reexport, or in-country transfer of luxury goods to Russia, Belarus, and to Russian or Belarusian oligarchs and malign actors anywhere in the world, effective 11 March 2022. Covered goods span over 570 HTS-6 line items across categories including spirits and tobacco (above de minimis thresholds), clothing and leather goods (>$1,000 per item), jewelry and precious gemstones, watches (>$100), vehicles (>$25,000), seafood/caviar (>$100), art and antiques, and recreational vessels. The rule targets both bulk commercial exports to Russia and Belarus and personal luxury procurement by designated oligarchs worldwide, with a policy of denial for all such licence applications.

Indonesia's Ministry of Trade issued Regulation (Permendag) No. 18 of 2021 on 1 April 2021, establishing an omnibus schedule of goods prohibited from export and goods prohibited from import. Global Trade Alert logs the measure as bundling an export ban and an import ban that took effect 19 November 2021, with tracked coverage spanning precious and semi-precious stones/metals, jewellery and related articles, and fertilizers/pesticides. The regulation consolidated and repealed several prior prohibited- goods instruments. It was later superseded by Permendag No. 47 of 2025.

Tanzania's Parliament enacted Act No. 5 of 2017, the Natural Wealth and Resources (Permanent Sovereignty) Act, as part of a landmark resource-nationalism legislative trio (alongside Act No. 6 on unconscionable contract renegotiation and Written Laws Miscellaneous Amendments No. 7), signed into law by President John Magufuli on 4 July 2017. The Act vests all of Tanzania's natural wealth and resources — minerals, oil and natural gas, fisheries, wildlife, forestry, water, and related sub-surface assets — as the permanent and inalienable property of the People of the United Republic, held in trust by the President on their behalf. Key operative provisions prohibit international commercial arbitration of natural-resource disputes (mandating adjudication within Tanzanian courts under Tanzanian law), empower Parliament to review and require renegotiation of any natural-resource arrangement containing "unconscionable terms," impose an in-country banking rule on earnings from natural wealth extraction, and authorise statutory override of contractual stabilisation clauses embedded in pre-2017 mining development agreements. The Act is the foundational parent statute underpinning all subsequent Tanzanian mining-sector reform, including the 2024 Written Laws (Miscellaneous Amendments) (No. 4) Act critical/strategic minerals classification and the 2025 Finance Act mining amendments.
