Africa's natural-resource advantage, Mwangi argued, will underpin the continent's strategic role as the world transitions to renewable energy and sustainable production.
"There will be no energy transition without strategic minerals," he said. "Africa is over-endowed. God was very generous."
Also addressing the forum, Lord Swire, Deputy Chairman of the Commonwealth Enterprise and Investment Council, said Kenya's evolution into a regional economic hub reflected long-term institutional progress.
"Kenya and its growth never cease to amaze me," he said.
"The opportunities are enormous, and I am astonished by what this country has become."
He said Commonwealth nations presented a ready trading bloc with structural efficiencies.
"It is cheaper for one Commonwealth company to do business with another, an audited advantage of 19%," he said.
"Don't forget the Commonwealth. Look closely at the opportunities within it."
The trade roadshow continues as part of Equity's wider international engagement programme linking Kenyan and regional companies to global capital sources.
On his part, Aliou Maiga, the Regional Industry Director for the Financial Institutions Group in Africa at the International Finance Corporation, said Africa must nurture a generation of visionaries who not only think boldly but also execute boldly.
He noted that this mindset is critical, especially at this point in the continent's development, where unlocking economic opportunities for a rapidly growing population will shape the continent's long-term trajectory.
"Africa needs people who think big and make things happen," Maiga said.
"This is relevant today, given where the continent is, and the urgent need to expand economic opportunities for our population. If we are able to create the right conditions and enable people to realise their potential, the future of this continent will be secured."
He emphasised that the World Bank Group's role is anchored in supporting countries to build resilient and competitive economies by offering resources and expertise that catalyse sustainable growth.
"As the World Bank, our mandate is to help develop economies by providing financial resources, technical expertise, and policy guidance to support sustainable development," he said.
"We work with governments, private sector partners, and communities to fund infrastructure, education, health systems, and innovation initiatives that can transform people's lives."
Maiga also highlighted East Africa as a continental pacesetter in innovation, describing the region as a fertile ground for digital transformation and entrepreneurial leadership.
"East Africa is at the forefront of innovation, leading the way in technology, entrepreneurship, and creative solutions across Africa," he said.
"This region has become a hub for startups, digital platforms, and tech-driven enterprises, fostering a culture of problem-solving and forward-thinking. That innovative spirit is driving economic growth, boosting job creation, and positioning East Africa as a key player in shaping Africa's role in the global knowledge and technology economy."
