Houlin Zhao, Secretary General of the International Telecommunication Union (ITU), pointed out that there are more than 1 billion people who are not banked but who have access to cell phones, so that they can be covered by a new wave of financial inclusion through mobile services. During the opening of WTDC 2017, Zhao reiterated the role of the "4I": Infrastructure-Investment-Innovation and Inclusion, as the pillars to achieve the UN Sustainable Development goals.
