Hong Kong’s $7.6 billion Indonesia bet masks a tariff evasion risk

Foreign direct investment from mainland China and Hong Kong into Indonesia reached $11.5 billion in the first half of 2026, nearly triple the $4.1 billion recorded a year earlier, according to the Investment Coordinating Board (BKPM). The surge, driven by US tariffs pushing manufacturers out of China, positions Indonesia as a key beneficiary of the ‘China plus one’ supply-chain realignment.

Hong Kong alone accounted for $7.6 billion of that total, a 230% increase from $2.3 billion, while mainland China’s investment more than doubled to $3.9 billion. The composition of the surge—and the route the money is taking—raises questions about how much of the capital is mainland Chinese money routed through offshore hubs.

Hong Kong’s foreign direct investment into Indonesia reached $7.6 billion in the first half of 2026.

A year earlier, the figure was $2.3 billion.

Mainland China’s investment more than doubled to $3.9 billion over the same period.

The combined $11.5 billion inflow, nearly triple the prior year, is being attributed to the US-China trade war. But the composition of that surge — and the route the money is taking — tells a more complicated story than simple diversification.

Some analysts have speculated that the Hong Kong surge reflects mainland firms routing capital through offshore subsidiaries, a pattern that could complicate US efforts to track tariff circumvention.

The investment is landing in nickel processing, data centres, and energy projects — sectors where Chinese companies already dominate. For Indonesia, the capital is welcome. For Washington, it raises questions about whether ‘China plus one’ is becoming ‘China via Hong Kong’.

The Hong Kong number that changes the story

BKPM data show Singapore remained the largest foreign investor in the first half of 2026 at $8.8 billion. Hong Kong followed at $7.6 billion, then mainland China at $3.9 billion, Japan at $1.9 billion, and the United States at $1.7 billion.

The year-on-year shifts are stark. Hong Kong’s FDI more than tripled from $2.3 billion in H1 2025. Mainland China’s more than doubled from $1.8 billion. Combined, China and Hong Kong accounted for the entire $7.4 billion increase in their combined flows year-on-year.

The shift in capital flows is easier to see than to read.

Indonesia’s Manufacturing PMI, compiled by S&P Global, returned to expansion at 50.2 in July 2026 after contracting at 46.9 in June, signalling that factory activity is strengthening alongside the investment surge. The rupiah, however, has weakened sharply, trading around 17,600–17,700 per US dollar in August, which makes Indonesian assets cheaper for foreign investors but raises the cost of imported capital goods.

Investment Minister Rosan Perkasa Roeslani said in a July 16 briefing that the country had reached 49.5% of its 2026 investment target by mid-year and stressed that strong inflows from Singapore, Hong Kong and China reflected sustained investor confidence despite global uncertainty.

Not everyone is cheering. The China Chamber of Commerce in Indonesia warned in a letter seen by Reuters in May that abrupt regulatory changes, higher taxes and a new nickel pricing formula are undermining confidence, even as Chinese firms remain major investors in nickel processing. Chinese firms faced “excessively stringent regulation, over-enforcement” and alleged corruption and extortion by authorities, the Chamber said.

BKPM data does not trace ultimate ownership, so the extent of mainland capital behind the Hong Kong figures remains an estimate. But the pattern is consistent with a routing strategy that analysts have raised concerns could complicate US enforcement efforts.

Chinese Foreign Minister Wang Yi visited Jakarta in August 2026, and both governments reaffirmed their commitment to deeper economic and investment cooperation. Indonesian analyst Rezasyah argues that Jakarta is pursuing a deliberate balancing act: leveraging Beijing’s capital and technology while maintaining its non-aligned foreign policy.

For a compliance officer at a Western manufacturer sourcing nickel from Indonesia, the Hong Kong surge is not an abstraction — it is a potential audit trigger under new US rules-of-origin enforcement.

Washington’s enforcement machine is watching

The investment surge lands just as the United States is tightening its scrutiny of supply chains that run through Southeast Asia. Recent US strategic documents explicitly target tariff evasion via third-country transshipment, and Section 301 probes are examining excess capacity and circumvention across several ASEAN economies, including Indonesia.

Washington’s Indo-Pacific Economic Framework is steering critical-mineral and electronics sourcing toward partners that meet labour, security and origin standards. For Indonesian-based exporters that rely heavily on Chinese inputs, the risk is that their goods could still face China-level tariffs if they fail US rules-of-origin tests.

Vietnam and Malaysia are already absorbing similar China-plus-one shifts in electronics, textiles and furniture. Analysts warn that US investigations into circumvention increasingly target ASEAN exporters, meaning Indonesia, Vietnam and Malaysia may all face tighter enforcement and potential 40% tariffs if local value addition and documentation fall short.

The next test arrives in October 2026, when BKPM releases Q3 investment data. If Hong Kong and China’s shares continue to outpace other sources, the tariff-driven relocation trend looks durable. If they stall, questions over regulatory friction and nickel pricing rules will grow louder. Either way, the capital is moving faster than the policy frameworks designed to govern it.

Beyond the headline

The Money Trail

The most consequential shift is not just more Chinese money, but how it moves. BKPM’s figures show Hong Kong nearly overtaking Singapore as an FDI source, with flows more than tripling year-on-year. Some analysts have speculated that this pattern is consistent with mainland firms routing capital through offshore hubs and Singapore-based subsidiaries, though BKPM data do not confirm ultimate ownership. Such routing, if occurring, could change who appears on paper as the investor of record and complicate US efforts to track and police tariff circumvention, turning jurisdictional choices into a core part of the investment story.

The Bigger Picture

Indonesia’s surge of China-linked FDI sits atop a broader transition from commodity dependence to downstream industrialisation financed by external capital. The combination of nickel processing, data centres and energy projects illustrates a strategy: turn resource endowments and a large domestic market into bargaining chips in a world of fragmented supply chains. What matters long term is whether these investments embed technology, local ownership and diverse partners, or lock Indonesia into single-supplier ecosystems dominated by one geopolitical camp.

What Isn’t Being Said

Official narratives stress headline FDI totals and non-aligned diplomacy, but say less about enforcement and exposure. US tariff rules increasingly treat ASEAN assembly with primarily Chinese inputs as China-origin, and Washington is expanding probes into transshipment and forced labour. If future decisions classify parts of Indonesia’s export base as circumvention, the apparent win of attracting Chinese and Hong Kong capital could translate into sudden market-access losses — a risk seldom acknowledged in celebratory investment briefings.

The decisions that follow the money

With US enforcement tightening and Indonesia’s investment data due for an October update, four groups face immediate choices.

• Western supply chain manager with Indonesian manufacturing exposure

  You need to assess how increased Chinese capital and potential US rules-of-origin enforcement affect your sourcing. Review the latest US trade enforcement notices from the Office of the United States Trade Representative, and map your Indonesian suppliers’ Chinese input content. Compliance costs are rising; a circumvention finding could disrupt your supply chain overnight.

• US-based investor with APAC emerging market exposure

  Evaluate your portfolio’s exposure to Indonesian sectors benefiting from the inflow — downstream metals, digital infrastructure, and energy. Monitor BKPM’s quarterly investment dashboards for shifts in Hong Kong and China’s shares. Regulatory friction and US tariff enforcement could increase volatility in these names.

• Western government trade policy analyst focused on Southeast Asia

  Analyse the implications of this capital redirection for US tariff effectiveness. The Hong Kong routing pattern suggests circumvention is already underway. Track Section 301 investigation updates and assess whether Indonesia’s non-aligned stance can withstand deepening economic ties with Beijing without triggering a US policy response.

• European multinational executive considering Indonesian market entry

  The growing presence of Chinese-backed industries will reshape competition, local partnerships, and the regulatory environment. Before committing capital, assess how Chinese dominance in nickel and data centres might affect your access to inputs, talent, and government licences. The window for entry is open, but the rules are being rewritten in real time.

Explainer

BKPM

The Investment Coordinating Board (Badan Koordinasi Penanaman Modal) is Indonesia’s primary investment agency, responsible for promoting and tracking foreign and domestic investment. It publishes quarterly realization data through the LKPM reporting system, which requires companies to report capital spending every four months. The H1 2026 figures showing the surge from China and Hong Kong were released by BKPM on 16 July 2026.

Danantara

Danantara is Indonesia’s state asset management fund, created to oversee strategic projects in energy, infrastructure and downstream industries. It manages the dimethyl ether (DME) gasification and waste-to-energy projects that have drawn Chinese participation. At least six such projects involve Chinese firms, aligning with Jakarta’s push to move beyond raw commodity exports.

China plus one

A business strategy in which companies diversify manufacturing and supply chains beyond China by adding production bases in other countries, typically in Southeast Asia or South Asia. The strategy accelerated after US tariffs on Chinese goods rose sharply in 2018 and again in 2025–2026. Indonesia, Vietnam and India are among the main beneficiaries, but the strategy now faces US scrutiny over whether the “plus one” locations are merely conduits for Chinese inputs.

Section 301

A provision of the US Trade Act of 1974 that authorises the President to investigate and respond to unfair trade practices by foreign countries. The US has used Section 301 to impose tariffs on Chinese goods and, more recently, to probe excess capacity and circumvention in ASEAN economies. If Indonesian exports are found to rely primarily on Chinese components, they could face the same tariffs as goods shipped directly from China.

Downstream processing

Indonesia’s policy of requiring raw minerals to be processed domestically before export, rather than shipped as ore. The goal is to capture more value, create jobs and build industrial capacity. Nickel processing has been the flagship, attracting billions in Chinese investment, but the policy now faces friction over new pricing rules and regulatory changes that have drawn complaints from the China Chamber of Commerce.

PMI

The Purchasing Managers’ Index is a monthly survey-based indicator of manufacturing sector health. A reading above 50 signals expansion; below 50 indicates contraction. Indonesia’s PMI, compiled by S&P Global, fell to 46.9 in June 2026 before rebounding to 50.2 in July, suggesting that the investment surge is beginning to translate into factory activity.
