On the morning of May 8, 2026, Indonesia’s Directorate General of Mineral and Coal held a public consultation that sent mining stock indices into freefall. TINS collapsed 14.88%. INCO fell 13.89%. MDKA shed 13.12%. The IHSG closed down 2.86% — the steepest single-day drop among Asian markets that week. The official narrative: royalty rate adjustments. The real story is far more consequential. Jakarta was not adjusting a tax schedule. It was repricing the terms of an entire geopolitical arrangement — one that has allowed China to treat Indonesia’s mineral wealth as a subsidised cost centre for its own industrial empire.

To understand what is actually happening, you must first understand what China built here — and why it worked so well, for so long, entirely at Indonesia’s expense.

Between 2013 and 2024, Chinese capital did something remarkable in Indonesia. It did not merely invest in mining. It constructed a vertically integrated extraction architecture — spanning ore, smelting, refining, logistics, power, and offtake — that effectively converted Indonesia’s sovereign mineral reserves into an offshore cost centre for China’s stainless steel and EV battery industries.

The numbers are precise and disturbing. Chinese firms now control approximately 75% of Indonesia’s nickel refining capacity. Tsingshan Holding Group alone holds a 66% effective stake in the Indonesia Morowali Industrial Park — the largest nickel processing complex on earth, covering 4,000 hectares, housing over 54 companies, and employing 80,000 workers. Jiangsu Delong, through PT Virtue Dragon Nickel Industry, PT Obsidian Stainless Steel, and PT Gunbuster Nickel Industry, commands over 38% of 2023 refining capacity independently. Together, Tsingshan and Delong account for more than 70% of Indonesia’s nickel output.

The financial architecture behind these operations carries its own strategic weight. The initial USD 1.22 billion investment for PT IMIP came from the China Development Bank — an institution overseen by China’s State Council. PT Indonesia Tsingshan Stainless Steel received additional loans from China Development Bank and Bank of China worth over USD 570 million. This was not private commercial capital seeking returns in an emerging market. This was state-directed financing securing strategic supply chains at sovereign scale.

What China built in Indonesia cannot be replicated quickly by any other actor. It is not merely smelting capacity. It is an entire ecosystem: Chinese-designed infrastructure, Chinese-trained technicians, Chinese-owned power plants running on Indonesian coal, and Chinese logistics routing ore from Indonesian soil directly into Chinese industrial supply chains — often without meaningful price discovery at any intermediate stage.

The most consequential — and least discussed — feature of China’s Indonesia strategy is not ownership. It is price control. China did not merely invest in Indonesian nickel to secure supply. It invested to control the global price of nickel itself, using Indonesia’s massive reserve base as a production weapon.

Between January 2023 and July 2024, the price of nickel fell 47% on the London Metal Exchange. This was not a demand shock. It was a deliberate supply flood engineered through Chinese-controlled Indonesian production. Indonesia’s market share in global nickel production expanded from 31.5% in 2020 to over 60% in 2024 — driven entirely by Chinese-backed capacity additions that priced Western and Australian competitors out of existence.

The casualties were precisely calculated. BHP Group suspended its Nickel West operations in Australia. Anglo American divested two Brazilian nickel mines. New Caledonian producers shut down. The global nickel development pipeline contracted to a fraction of what future demand will require — because no non-Chinese producer can undercut a supply chain that receives state-subsidised financing, operates on Indonesian coal at regulated domestic prices, and books profits in jurisdictions outside Indonesia’s tax reach.

This is the transfer pricing architecture at the core of China’s Indonesia play. The mechanism works across three layers.

The evidence for this mechanism is not merely analytical. The European Union’s trade investigation found direct discrepancies between the prices Tsingshan-linked companies in Indonesia paid for nickel ore versus international market prices — confirming below-market intra-group transactions. The KPK has documented Rp 15.9 trillion per year in estimated tax shortfalls from the mining sector. By 2017, cumulative PNBP arrears in the minerba sector had reached Rp 25.5 trillion.

Perhaps the most telling evidence: China has imposed anti-dumping duties of 20.2% on stainless steel imports from Indonesia — products manufactured almost entirely by Chinese-owned companies operating in Indonesia. Beijing is simultaneously benefiting from cheap Indonesian production and protecting its domestic industry from that same production’s price competition. Indonesia is being used as a pressure valve for Chinese industrial overcapacity, with none of the upside accruing to the Indonesian state.

The revision of PP 19/2025 is publicly framed as a fiscal optimisation exercise. That framing is tactically useful and strategically misleading. What the government is actually deploying is a sovereign pricing instrument — one that structurally neutralises the transfer pricing architecture that has allowed China to operate in Indonesia at artificially low effective costs.

The key technical mechanism is the Harga Mineral Acuan, or HMA — the government-set mineral reference price that forms the basis for all royalty calculations. Unlike transaction prices, which Chinese operators can manipulate through intra-group contracts, the HMA is determined by Indonesia’s Ministry of Energy and Mineral Resources — now at its own discretion, twice per month, no longer tethered to an explicit average of international commodity indices. This is a critical and underappreciated design feature.

The PNBP baseline from the minerba sector reached Rp 138.37 trillion in 2025 — exceeding its target despite declining nickel and coal prices. For 2026, the government set an initial target of Rp 134 trillion before the royalty revision proposal was announced. With the revision in play and commodity prices significantly elevated across gold, copper, tin, and silver, the fiscal arithmetic shifts substantially.

Based on confirmed production volumes, elevated HMA prices, and proposed tariff structures, this analysis estimates the royalty revision will generate an additional Rp 13–18 trillion per year above the 2026 baseline — pushing total PNBP minerba toward Rp 147–152 trillion. This estimate is the author’s own calculation based on publicly available data from ESDM, Ditjen Minerba, and market pricing from Argus and SMM. No official government projection has been released at time of publication.

A critical clarity is required here, however. The royalty revision does not exclusively hit Chinese operators. The distribution of fiscal impact follows the structure of mineral ownership in Indonesia — and that structure is uneven across commodities.

The picture that emerges is more nuanced than the headline narrative suggests. The royalty revision hits China hardest precisely where China is most entrenched — nickel refining and cobalt extraction. For gold, copper, and tin, the primary impact lands on state-owned and Western-affiliated operators. This is not a flaw in the policy design. It is an accurate reflection of the ownership map Indonesia currently faces, and it underscores why the cobalt royalty — almost entirely extracted by Chinese HPAL operators — is the most strategically significant element of the revision. The USD 600 million in potential annual cobalt royalty revenue represents value that China has captured for years with zero payment to the Indonesian state.

Of all the commodity-specific dynamics in this analysis, the tin story contains the most explicit statement of intent from any market participant. At PT Timah’s Annual General Shareholders Meeting on June 12, 2025, Director Suhendra made a statement that deserves to be read carefully by anyone tracking Indonesia’s mineral sovereignty trajectory.

This is not an analyst projection or a think-tank estimate. This is an Indonesian state enterprise director, at a formal shareholders meeting, stating that a potential combination with China’s Yunnan Tin — which controls roughly 50% of global refined tin production to PT Timah’s 13–15% — would produce an entity capable of setting the world price of tin. The strategic partnership between Yunnan Tin and PT Timah was formalised in September 2024.

The proposed royalty increase on tin — from a range of 3–10% to 5–20%, the largest percentage increase of any commodity in the revision — must be read in this context. If PT Timah and Yunnan Tin achieve sufficient market coordination to manage global tin prices upward, Indonesia’s royalty take scales automatically with HMA. The progressive structure means that at the current HMA of USD 51,101 per ton, Indonesia is already collecting near the top of the new tariff range. Every USD 1,000 increase in the tin price above USD 50,000 per ton directly increases Indonesian state revenue at the 20% rate. Indonesia has positioned its fiscal instrument to benefit from the very price cartel its own state enterprise is contemplating joining.

While public attention has focused on nickel, China’s aluminum-bauxite play in Indonesia is accelerating on a trajectory that mirrors the nickel story almost exactly — with one critical difference: Indonesia has already watched the nickel model play out and is now responding pre-emptively through the royalty revision rather than after-the-fact.

Tsingshan commissioned its first Indonesian aluminum smelter in 2023. China Hongqiao operates a 2-million-tonne-per-year alumina facility in Kalimantan, divided across two operational phases. Shandong Nanshan is completing a 250,000-tonne smelter on Bintan island, due operational in 2026. Goldman Sachs projects Indonesian aluminum production will rise five-fold by the end of the decade — driven overwhelmingly by Chinese capital. In July 2025, Bloomberg reported that Chinese metals tycoons were “turbocharging Indonesia’s aluminum industry with multi-billion dollar projects that rival the vast bets made on the country’s nickel riches roughly a decade ago.”

Asia Times, in an April 2026 analysis, framed the dynamic with precision: China’s aluminum sector is effectively exporting its capacity constraints — recreating domestic Chinese production in Indonesia, locking in supply chains while maintaining influence over output. Indonesia risks becoming an offshore extension of China’s industrial policy — not for the first time.

The bauksit provisions in the royalty revision are not incidental. They are Indonesia’s attempt to ensure that the aluminum chapter does not repeat the terms of the nickel chapter — where Chinese capital extracted value for a decade before the Indonesian state moved to capture its share.

In July 2024, ACH Metals Australia — a subsidiary of Indonesia’s Salim Group — acquired Rex Minerals, operator of the Hillside copper-gold project in South Australia, for USD 265 million. Rex Minerals holds 1.9 million tonnes of copper and 1.5 million ounces of gold in resources. The acquisition was announced through the Australian Stock Exchange, subject to FIRB approval. Bumi Resources, Delta Dunia Makmur, and Sinarmas Group have separately built positions in Australian mining assets.

This pattern requires explanation. The Salim Group is not a mining conglomerate by heritage. Its core identity is Indofood — instant noodles, consumer goods, FMCG. Anthoni Salim holds stakes in Amman Mineral and led a consortium that acquired a USD 1.6 billion stake in Bumi Resources in 2022. The aggressive move into Australian hard assets is not diversification. It is repositioning.

Read against the backdrop of everything documented in this analysis, the Salim Australia play carries a clear strategic logic. Australian assets sit in a transparent, rule-of-law jurisdiction with established price discovery — where commodity prices cannot be manipulated through intra-group transfer pricing, where royalty regimes are stable and internationally benchmarked, and where ownership is protected by treaty-level investment agreements. They are, in the precise sense of the term, assets beyond the reach of Beijing’s industrial policy.

The conglomerate-level reading is this: Indonesia’s most sophisticated business families are hedging against the very dynamic this article documents. If China’s market power over Indonesian commodity prices is structurally disrupted — which is precisely what the royalty revision, combined with RKAB annual controls and HMA sovereignty, is designed to achieve — the value of Indonesian mineral assets will reprice upward. Salim is building exposure to the revaluation on both sides of the trade: through AMMN in Indonesia, and through Australian hard assets that represent the non-Chinese alternative supply that global buyers will increasingly need.

The base case — a negotiated compromise that partially implements the revision — is not a defeat for Indonesia’s sovereign pricing agenda. It is the expected first move in a multi-year repositioning. The structural mechanisms that matter most (HMA-based calculation, annual RKAB controls, cobalt inclusion in the HPM formula) are already partially in place and are difficult to reverse without triggering far greater diplomatic cost than adjusting a tariff bracket. The direction is set. The pace is negotiable.

The window that matters is 2026 to 2028 — while commodity prices remain elevated, while China’s domestic nickel oversupply problem limits its ability to threaten credible exit from Indonesian operations, and before the bauxite-aluminum wave fully consolidates into the same ownership structure as nickel. Indonesia has, for the first time in the modern era of Chinese mineral investment, a genuine pricing advantage over its largest investor. The question is whether it will use it with the discipline the moment requires.

Indonesia does not need to expel Chinese capital from its mining sector. That capital built real infrastructure, created real employment, and positioned Indonesia as the dominant force in global nickel production. None of that is undone by a royalty revision. What the revision attempts — if executed with strategic coherence — is a fundamental repricing of the terms on which that capital continues to operate. Not charity. Not exploitation. A fair price for access to the world’s most critical mineral reserves, in the most important decade for the energy transition.

China built an empire in Indonesian soil. Jakarta is finally invoking its right as landlord.
