Singapore seized then-Megaspeed chief executive Alice Huang's passport in June 2025 and held it for eight months while seeking U.S. help investigating whether advanced Nvidia chips were shipped toward China, CBS News reported Friday, citing people familiar with the matter¹.

One source told CBS that officials in Washington were "not forthcoming" and that Singapore received no meaningful help while Huang was in the city-state, and that no substantive U.S. assistance has been provided to date¹.

Singapore's Home Affairs Ministry said this week that it asked the U.S. Department of Justice and the FBI for help, CBS reported¹. Police first raised the issue with U.S. authorities in July 2025 to seek Super Micro Computer Inc.'s cooperation on where servers ultimately went, and repeated those requests on several occasions, according to the ministry statement as described by CBS¹.

Since February 2025, Singapore has been investigating whether Huang and Megaspeed worked with San Jose-based Super Micro to ship servers equipped with Nvidia chips to China, a source told CBS¹. Huang, a Chinese national, flew to Singapore in June 2025 for a voluntary interview with U.S. Bureau of Industry and Security investigators as part of a post-shipment verification check requested by American authorities, CBS said, citing the source and a Thursday Home Affairs statement¹.

Singapore police interviewed her the same day and impounded her passport¹. By February 2026 they had not charged her and returned the passport, the source said; she was barred from returning after authorities assessed she had given inaccurate information about her role at Megaspeed¹.

The ministry said suspected domestic offenses involved potential false declarations about server purchases¹. A second source told CBS the servers may have gone to Malaysia, with investigators suspecting some or all may then have been sent onward to China¹. Megaspeed has denied any wrongdoing¹.

The ministry said Super Micro provided limited cooperation¹. Malaysian Prime Minister Anwar Ibrahim said Friday there was no indication chips linked to the Nvidia-Megaspeed issue had been re-exported, CBS reported¹. China's Foreign Ministry has called spy claims about Huang groundless speculation, CBS said¹.

Six other people linked to Megaspeed are wanted for questioning and have not been in Singapore since the investigation began, the ministry said¹. Singapore has charged five other people in a wider, separate fraud case related to suspected Nvidia chip transfers, including one Chinese man charged Friday, according to CBS¹.
