South Korea will soon unveil plans to reduce its economy's reliance on Japanese industries, its finance minister said Wednesday, while repeating his call for Tokyo to end the tightening of controls on some exports.

"The government is working on comprehensive plans to reduce the country's dependence on Japan's materials, components and equipment industries and will announce them soon," Finance Minister Hong Nam-ki said at the start of a regular meeting of economy-related ministers.

He added that South Korea wanted to make its supply chain more independent.
