Chinese National Dies in ICE Custody on Saipan as Beijing Demands Answers, While US Presses China Over Two Detained Americans

A death in Saipan, a demand from Beijing

Lianyong Wei, 51, died August 23 at a hospital in the Northern Mariana Islands, hours after being taken into ICE custody, according to an ICE news release reported by the Associated Press. The Chinese Consulate General in Los Angeles says it has been notified and is pressing U.S. authorities for a full accounting.

"We have expressed serious concerns to the relevant U.S. authorities over this incident and required a timely and thorough investigation into the cause of Mr. Wei's death, notification of the findings, measures to prevent any recurrence of similar incidents, and assistance to the family of the deceased in handling the aftermath," the consulate said in a statement carried by the AP.

Here are the facts on the record. Wei entered the Northern Mariana Islands in February 2019 on a two-week authorization and stayed for more than seven years, according to ICE. He was arrested August 21 by Northern Mariana Islands Department of Public Safety officers on criminal charges stemming from an alleged assault on a family of five at their home, ICE said. He was transferred into ICE custody the next day pending removal proceedings, which had begun in July 2026 with a hearing scheduled for this month.

ICE says a guard at the Saipan lockup found Wei unresponsive during routine morning checks on August 23. He was taken to a hospital ER, where he was pronounced dead after "life-sustaining interventions were initiated." The cause of death is under investigation. No findings have been released.

What ICE hasn't answered

ICE has not said whether Wei received the medical intake screening the agency promises detainees within their first 12 hours in custody. Medical experts cited by the AP say a thorough intake exam is critical to catching conditions that can turn fatal in detention. Its absence, or ICE's silence on whether it happened, is a legitimate gap.

The agency also took more than a week to publicly acknowledge the death, even though local authorities in the Northern Mariana Islands announced it August 24. ICE's own policy calls for a news release within two business days. Northern Mariana Islands corrections commissioner Anthony Torres said in a statement that the department is "reviewing relevant procedures and will implement any necessary corrective actions to strengthen prevention and response measures."

Wei is at least the fifth Chinese national to die in ICE or Border Patrol custody since March 2025, according to AP tracking. Two of the first four deaths were ruled suicides; the other two were attributed to medical complications. Across all nationalities, at least 57 ICE detainees have died since President Trump returned to office in January 2025, a toll the AP reports has drawn concern from public health experts, immigrant advocates and the Mexican government. An agency processing detainees at this volume should have a transparent, fast-reporting system, and a week-long delay on a custody death doesn't meet that bar.

What isn't established: any finding of negligence or wrongdoing by ICE staff in Wei's death. The cause remains under investigation, and no charges or disciplinary findings have been announced.

The other side of the ledger

While Beijing presses Washington over Wei's death, the U.S. government is pressing Beijing over two of its own citizens. Secretary of State Marco Rubio has designated Min Zin, a Burmese-American political scientist and PhD candidate at UC Berkeley, as wrongfully detained in China, according to Fox News and the Epoch Times. Zin was arrested June 3, 2026, in Yunnan province after traveling to China at the government's own invitation to attend an academic conference. Chinese authorities accuse him of endangering national security and espionage. Beijing has denied that wrongful detention occurs in China and says such cases follow Chinese law.

Assistant Secretary Dylan Johnson said the State Department will "continue to advocate for Mr. Zin and call for the release of all U.S. citizens who are arbitrarily detained or exit banned in China." A senior State Department official told Reuters that Zin's family lost contact with him for 48 hours after his arrival before learning where he was.

The other American on the wrongful-detention list is Dr. Youlin Chen, a Chinese-born seismologist from Boston who has been held nearly two years without trial, according to the Epoch Times. His case only became public in July.

Both designations land weeks before Xi Jinping's expected September 24 visit to the White House, according to Fox News. Beijing's demand for a swift, transparent U.S. investigation into Wei's death raises a question about whether it applies the same standard to its own handling of detained Americans, two of whom have been held for months to years without trial or public evidence. Beijing hasn't addressed that comparison in its public statements. Neither government has said whether Wei's death or the American detainees will be raised directly at the Xi meeting.

The unresolved facts: what killed Lianyong Wei, whether he got the medical screening ICE promises, and whether Rubio's wrongful-detention designations move Beijing to release Min Zin and Youlin Chen before or during Xi's visit.
