Having spent my career growing businesses and championing innovation, I see tremendous potential to broaden our cooperation, particularly across business ventures, defence modernisation, space innovation, advanced technologies and the financial sector - areas where our partnership offers unique opportunities for meaningful impact," the ambassador said. "I look forward to working closely with the government, private sector and Luxembourg’s vibrant community of innovators. I believe our partnership can serve as a model for how two like-minded nations, united in ambition, can turn shared vision into transformative results for our economies, collective security and our people."
