MOSCOW — A Moscow court suspended the embezzlement trial of an AIDS-stricken former executive of Yukos and ordered prison doctors to determine if he should be moved to a specialized clinic.

Vasily Aleksanian’s defense team insists that he be moved to a hospital outside the prison for treatment. The oil company’s vice president is dying of AIDS and also has tuberculosis, his lawyers say. The European Court of Human Rights has demanded repeatedly that he be transferred to an outside clinic.

“Treatment in the prison is completely unacceptable to the European court, and it is placing him at further risk,” a lawyer for Mr. Aleksanian, Drew Holiner, said by telephone yesterday from London. “We’re not happy until he gets moved to a hospital and starts getting the treatment he should be getting.”

Mr. Aleksanian was detained on charges of money laundering and embezzlement soon after joining Yukos in 2006 with the power to act as head of the company, which was in the process of being dismantled by the state over tax claims. Yukos was once Russia’s biggest company by market value and its largest oil producer.

He has accused Russian authorities of offering to release him only if he testifies against Yukos’s former chief executive, Mikhail Khodorkovsky, who has been on a hunger strike since January 29 to protest Mr. Aleksanian’s detention.

Mr. Aleksanian, 36, was diagnosed with HIV, the virus that causes AIDS, a few months after his arrest in April 2006. Prison officials have said he refused antiretroviral drugs. His lawyer Yelena Lvova denied this claim.
