He said his administration had made significant progress in meeting the challenges.
Jonathan spoke while receiving the new Ambassador of Switzerland to Nigeria, Mr. Hans-Rudolf Hodel, who was at the Presidential Villa, Abuja, to present his letter of credence.
“We are making significant progress in meeting our recent security challenges and we shall continue to improve; so, investors have nothing to fear,” he assured.
The President, who received three other ambassadors at different ceremonies, urged them to encourage more business delegations from their countries to visit Nigeria.
“Nigeria is a huge market with many green areas waiting for investors. I urge you to prepare the ground for more robust economic relations between our countries,” he said.
