Over 30 chief executives of German and Indo-German companies will participate in the "Indo-German Summit 2002", to be held here next month, to assess new areas for promoting investments in Rajasthan. German ambassador to India Heimo Richter will be the guest to be organised by Indo-German Chamber of Commerce on March 9, an official release said in Jodhpur on Thursday. The chamber had organised a similar meet in Jaipur in March last year in view of the state government's plans to make the desert state a preferred location for investment in certain identified sectors.
