Former Soviet President Mikhail Gorbachev as he bids the last farewell to his wife Raisa Gorbacheva during the funeral ceremony in Moscow, Russia, 23 September 1999 (reissued 30 August 2022). According to a Moscow Central Clinical Hospital statement, former Soviet president Mikhail Gorbachev has died at the age of 91. As a supporter of the de-Stalinization programs of his predecessor Nikita Khrushchev, Gorbachev initiated numerous reforms during his tenure. He signed a nuclear arms treaty with the United States and withdrew the Soviet Union from the Soviet-Afghan war. His policies created freedom of speech and press, and decentralized fiscal policy planning and execution to increase efficiency. Gorbachev was the last leader of the Soviet Union, overseeing Russia’s transition from one party rule to fragile democracy. (Photo by Sergey Chirikov/EPA/EFE)

In this March 15, 2012 file photo, a Chinese woman poses for photos near a sculpture depicting a Chinese yuan note at an art district in Beijing, China. China devalued its tightly controlled currency on Tuesday, August 11,2015, following a slump in trade, triggering the yuan's biggest one-day decline in a decade. The central bank said the yuan's 1.3 percent fall was due to a change aimed at making its exchange rate controls more market-oriented. But any change raises the risk of tensions with China's trading partners. (Photo by Ng Han Guan/AP Photo)
