From Sept. 9-10, the 18th annual Group of 20 Summit — an intergovernmental platform that includes 20 of the world’s largest economies — took place in New Delhi, India. Its members include 19 sovereign states alongside the European Union and the African Union. This group accounts  for nearly two-thirds of the global population, as well as over 75 percent of worldwide trade and 85 percent of global GDP, according to the G20 Secretariat. It was founded in 1999 following the Asian financial crisis as a call to facilitate global economic cooperation.
