The White House has taken steps to address national security concerns surrounding SK Telecom's access to Anthropic's advanced AI model, Mythos. The decision to revoke the carrier's access was made due to ties between SK Telecom's parent company, SK Group, and China.

SK Group has extensive interests in Chinese semiconductors, energy, and other sectors, which has raised concerns about the potential for sensitive information to be shared with China. Despite SK Telecom's relatively small footprint in China, generating $1.9 million in revenue and employing seven people in 2024, the carrier's history in the country is significant.

In 2004, SK Telecom formed a wireless joint venture with state-owned China Unicom, and in 2006, it invested $1 billion in China Unicom convertible bonds. The bonds were later sold for $1.3 billion, but SK Telecom retained a residual interest.

The move to revoke SK Telecom's access to Mythos came days before export controls were imposed on the model, pulling it offline for foreign nationals. The decision highlights the growing concerns about the potential risks associated with advanced AI technology and the need for stricter controls on its distribution.
