Between 10,000 and 20,000 Chinese people are estimated to live in Belgrade and, since their arrival in the mid-1990s, Block 70 in New Belgrade has been known colloquially as the Chinese quarter. Many Middle Easterners, mainly from Syria, Iran, Jordan and Iraq, arrived in order to pursue their studies during the 1970s and 1980s, and have remained in the city. Throughout the 19th and early 20th century, small communities of Aromanians, Czechs, Greeks, Germans, Hungarians, Jews, Turks, Armenians and Russian White émigrés also existed in Belgrade. There are two suburban settlements with significant minority population today: Ovča and the village of Boljevci, both with about one quarter of their population being Romanians and Slovaks, respectively.
