Brazil launched what it called a social summit Thursday ahead of next week's Group of 20 meeting of top economies, the first such event focused on drawing civil society input ahead of the main annual summit.
Foreign Minister Mauro Vieira said 40,000 people from G20 countries were expected to attend meetings and panels through Saturday in revamped warehouses of downtown Rio de Janeiro's port area and nearby Museum of Tomorrow. The main summit takes place in Rio on Monday and Tuesday.
