China's shark finning practices face potential US sanctions after a formal petition from the Center for Biological Diversity. The conservation group accuses Chinese-flagged vessels of intentionally cutting fins off sharks and discarding them at sea. With shark populations down 70% since 1970, conservationists argue China fails to meet American standards under the US Moratorium Protection Act.

The petition risks banning all $1.5 billion of Chinese seafood imports to the US. Unlike over 90 jurisdictions requiring fins naturally attached to sharks, China allows ratio-based regulations. Conservationists highlight these rules as ineffective, difficult to enforce, and ignoring biological differences between species. Chinese crews have reportedly targeted blue sharks, tiger sharks, and pelagic threshers.

The petition exposes China's role as the world's largest fishing fleet without proper shark conservation measures. "Losing sharks wouldn't just be an ecological disaster; it would be a profound moral failure," said Alex Olivera of the Center. While China claims commitment to science-based conservation, the petition directly challenges their practices as violations of international conservation standards.
