Thomas D'Agostino, the Under-Secretary for nuclear security said, "We do work with Pakistan, with the Department of Homeland Security, on Secure Freight Initiative, in putting radiation detectors in their ports. One port is done. Karachi is the second port. We're negotiating that type of work."
He also said, "We have our export controls experts who are in the process of working with Pakistan, on training on what to look for with respect to what comes into the country and goes out of the country."
"Pakistan has legislation in place as a nation to establish this type of capability and maintain it. They have developed their own lists of materials and advanced their lists of materials on things that they are looking for," he added.
