ULAANBAATAR, MONGOLIA - JUNE 11: A 20-year class reunion gathers for photos in Chinggis Square (formerly Sukhbaatar Square) on June 11, 2015 in Ulaanbaatar, Mongolia. A few years ago, Mongolia boasted one of the world's fastest growing economies, but, for the past few years, Mongolia's economic growth has fluctuated greatly. Mongolia's current prime minister is pushing for an increase in foreign investment to stabilize the economy, including a deal to expand the massive $6.5 billion Oyu Tolgoi mine.
