US expresses disappointment over Chinese court's decision to uphold American's death sentence.

The US State Department expressed disappointment over a Chinese court's decision to uphold the death sentence for American citizen Mark Swidan, who has been detained in China for over a decade on drug-related charges. Swidan's mother has alleged that he has undergone physical and psychological torture while in detention. The United Nations working group has concluded that Swidan's detention is arbitrary and in violation of international law. The US government has repeatedly expressed concerns about Swidan's treatment and called for his immediate release.
