Why Singapore Keeps Surfacing in Nvidia Chips and China Controversy

Singapore, a hub for billions of dollars of Nvidia sales each year, finds itself increasingly in the crosshairs of Washington’s efforts to block advanced AI chips from reaching China, as the chipmaker’s CEO scandal once again puts the city-state in the spotlight.

The Southeast Asian nation said Thursday it had barred Alice Huang, the businesswoman at the center of a scandal that catalyzed the end of Jensen Huang’s tenure as Nvidia CEO, from re-entering the country.

A fifth person was indicted on Friday on 41 charges in a Singapore fraud case involving computer servers believed to contain Nvidia chips and exported to Malaysia. The alleged transactions in the broader case totaled about $390 million, prosecutors said in March last year.

Investigations into several key companies and officials, including Megaspeed International, began in February 2025 and continued on Thursday.

Authorities were investigating whether servers exported via Singapore to Malaysia without entering the domestic market were then redirected to another destination, contrary to claims made in Singapore, the Home Ministry said in a statement on Thursday.

Singapore faces growing international scrutiny, particularly from the United States, due to its role as a major billing and potential transit hub for Nvidia chips that U.S. officials say have reached China.

The United States has imposed restrictions on the export of Nvidia’s most advanced AI chips to China since 2022 to curb Beijing’s accelerated AI development.

Nvidia’s Singapore-related revenue rose to 22% in the fiscal quarter ending July 2025, from 8% in 2023, with the country’s Commerce Ministry estimating that chips physically delivered there represented an increase. for less than 1% of the chip manufacturer’s turnover.

Experts have pointed to gaps in the enforcement of U.S. export restrictions and in Singapore’s corporate system that make it difficult to trace advanced Nvidia chips.

Nvidia chips can be legally sold to customers in other countries, such as Malaysia or Singapore, and then resold or illegally re-exported to China. Chinese companies can also legally remotely access the most advanced AI chips housed in data centers outside China rather than purchasing the hardware directly.

Chris McGuire, a senior fellow at the Council on Foreign Relations and a former U.S. national security official, said Southeast Asia has become “a major hub for chip smuggling and export control circumvention,” importing tens of billions of dollars worth of AI chips a year.

Singapore has stepped up efforts to control suspected chip misappropriations since last year, including investigating allegations of fraud and money laundering.

Officials recognized the “potential blind spots between monitoring trade flows and banking flows separately,” said Alvin Camba, senior scientist and research director at Lyvi, an Austin-based AI risk assessment company. Correlating physical shipments with associated financial transactions can be “difficult,” he added.

“Singapore’s strict corporate secrecy regulations, which provide extensive protections to foreign investors, can also make it difficult to quickly identify the true recipients of goods,” Camba said.

These challenges can be exploited to “obscure financial flows and potentially circumvent global restrictions on technology transfers,” he added, calling on regulators to constantly adapt.

Singapore said it received limited assistance from U.S. authorities in its year-long investigation.

Police sought information about Super Micro Computer Inc., a U.S. server vendor relevant to the investigation, but the company provided limited cooperation, according to Thursday’s statement.

The city-state first raised the issue with US authorities in July 2025 and has reiterated its request several times since September last year. “Despite these repeated requests, Singapore has so far received only limited information or assistance regarding the company,” it said.

Police questioned Alice Huang, a Hong Kong resident who was then CEO, president and key controller of Megaspeed, in June 2025.

In February 2026, authorities concluded that there was insufficient evidence that she had committed offenses related to the statements under investigation. However, she was barred from returning to Singapore after she was caught providing inaccurate information aimed at downplaying her role in Megaspeed.

The country does not enforce “unilateral export controls” imposed by other countries, the ministry said in a statement Thursday, but it expects companies operating there to take foreign export rules into account in their international business activities.

Megaspeed, spun off from a Chinese gaming company, has become Nvidia’s largest customer in Southeast Asia in less than three years and has purchased more than $4.8 billion worth of its chips since June 2024, according to the New York Times, although the company has denied any wrongdoing.

Alice Huang, who U.S. intelligence identified as a Chinese intelligence agent passing information to Beijing, served as Megaspeed’s chief executive for eight months in 2023 but reportedly continued to play a senior role at the company.

Jensen Huang resigned as CEO of Nvidia on Thursday, ending 33 years at the helm of the company after revelations that he had two extramarital affairs, plunging the chipmaker at the heart of the global AI boom into crisis.

Nvidia has named CFO Colette Kress as interim CEO while its board searches for a permanent successor.
