The governors of Georgia and South Carolina are keeping quiet on a private meeting on stalled efforts to build a $5 billion cargo port on the Savannah River shared by both states.

Georgia Gov. Nathan Deal and South Carolina Gov. Nikki Haley met for nearly two hours Friday at a private office building in Augusta, about midway between their respective statehouses. Both left without speaking to reporters.

Deal spokesman Brian Robinson says the meeting was "productive" but declined to give details.

It's up to Deal and Haley to resolve an impasse on plans for a jointly owned seaport in Jasper County, S.C. In December, South Carolina port officials voted to stop funding the project without Georgia agreeing to concessions including deeper water at the site than Georgia has sought.
