Japan will study the pros and cons of a free-trade agreement with the United States and is ready to restart FTA talks with South Korea, Cabinet ministers said Tuesday, a day after Washington and Seoul struck their own deal.

"We need to study advantages and problems (of an FTA with the U.S.) from the viewpoint of the entire people's interests," economic and fiscal policy minister Hiroko Ota said at a news conference.

Japanese and U.S. business groups have been seeking an FTA.
