[6] North Korea was able to gain access to funds deposited at the bank by raising the issue with the United States at the Six-party talks on nuclear weapons technology in Beijing.
[9] However, the United States agreed to resolve the issue of frozen Banco Delta Asia bank accounts, if North Korea disarms its atomic arsenal.
[11] On March 14, 2007, the U.S. Treasury Department ordered all U.S. banks and companies to sever ties with Banco Delta Asia, following an 18-month investigation.
U.S. Treasury Under-Secretary Stuart Levey stated that the investigation confirmed the bank's "willingness to turn a blind eye to illicit activity, notably by its North Korean-related client".
The sanctions were lifted without further litigation, or any admission of liability by any party, and Banco Delta Asia was left free to resume its US dollar business.
