U.S. prosecutors are investigating Thailand-based OBON Corp. for allegedly smuggling Nvidia AI servers to China, raising concerns about semiconductor export enforcement.
U.S. prosecutors are scrutinizing a Thailand-linked company, OBON Corp., over allegations of smuggling advanced Nvidia AI servers to China. This situation has sparked significant concerns regarding the enforcement of semiconductor export regulations.
According to a report by Bloomberg, OBON is suspected of diverting billions of dollars’ worth of Super Micro Computer servers equipped with Nvidia chips. Alibaba Group Holding Ltd. has been identified as one of several end customers involved in this alleged smuggling operation.
This year, U.S. prosecutors outlined a scheme in which a co-founder of Super Micro allegedly collaborated with an unnamed Southeast Asian firm and a “rotating cast” of third-party brokers to circumvent U.S. trade laws. While the prosecutors did not explicitly name the firm, sources have identified it as Bangkok-based OBON Corp.
An Nvidia spokesperson emphasized the company’s commitment to compliance, stating that it expects all ecosystem partners to adhere to strict regulations. The spokesperson also noted that Nvidia will continue to work with the government to enforce these rules. In a separate statement, Alibaba denied any business relationships with Super Micro, OBON, or the third-party brokers mentioned in the indictment. The company asserted that banned Nvidia chips have never been utilized in its data centers.
The United States has previously prohibited the export of high-end Nvidia chips to China due to concerns that they could be repurposed for military applications. However, a recent decision allowed the export of Nvidia’s H200 processors, its second-best AI chips, to China, suggesting a resolution to the debate over whether Nvidia and its competitors should continue selling to China or restrict exports.
There had been uncertainty regarding whether Chinese authorities would approve the import of these chips, but this approval was finally granted in March.
OBON, which remains relatively unknown outside of technology circles, is involved in Thailand’s national AI initiative, having created Siam AI, the country’s sovereign cloud champion. A May 2024 press release indicated that OBON planned to deploy Nvidia servers in a small data center in Bangkok to support the launch of Siam AI Cloud and advance Thailand’s AI strategy. Siam AI was established as a separate entity just four months prior to this announcement.
Ratanaphon Wongnapachant, CEO of Siam AI, stated in an interview with Bloomberg that he left OBON when he founded Siam AI and could not comment on the U.S. suspicions regarding OBON’s alleged smuggling activities. “I will only answer regarding Siam AI, which is that the company is not involved in this,” he said.
The allegations against OBON could complicate Thailand’s ambitions in the AI sector and have reignited discussions in Washington about imposing stricter restrictions on semiconductor sales to the region. Although the U.S. has considered implementing semiconductor export restrictions on Thailand in the past, such measures have yet to be enacted.
As the investigation unfolds, the implications for both OBON and Thailand’s AI initiatives remain to be seen. The case highlights the ongoing tensions surrounding semiconductor exports and the geopolitical implications of technology in the region.
According to Bloomberg, the outcome of this investigation could have significant ramifications for the future of AI development in Thailand and the broader Southeast Asian market.
