India has asked Germany to de-link New Delhi from pre-permit group to promote bilateral export. The de-linking will enable India to export commodities under certain categories to Germany without license in the absence of free trade agreement between the two countries. Addressing the inaugural of the 17th session of Indo-German Joint Commission on Industrial and Economic Co-operation in New Delhi today, the Finance Minister Pranab Mukherjee invited German investors to invest in India in various sectors. He said that public-private partnership mode is an attractive opportunity for German investors to invest in the country. He said, Delhi-Mumbai and Chennai-Bangalore Freight Corridors are such an opportunity in road sector. In his opening remark, the German Minister of Economics and Technology, Mr. Rainer Brueberle said that India has a high potential in IT sector while Germany can contribute in various ways in developing India's energy sector.

On free trade agreement between the two countries, the visiting dignitary said, that some sort of flexibility will be achieved for final settlement.
