Q&A: Bill Gates, co-founder of Microsoft and co-chair of the Bill & Melinda Gates Foundation

President Xi Jinping and other global leaders will get together at the United Nations to agree on the Sustainable Development Goals. What is your view about that?

It is a great opportunity to take stock of how the world's poorest are doing, and there is a big push to spread the word about the SDGs. Melinda and I will be in New York to help get the news out. We believe these goals will make a big difference, as the world has already done something like this, and with great success. Fifteen years ago, world leaders adopted the Millennium Development Goals, which was one of the best ideas for improving lives that I've ever seen.
