Ethnic Chinese in Russia officially numbered 39,483 according to the 2002 census. However, this figure is contested, with the Overseas Chinese Affairs Commission of the Republic of China on Taiwan claiming 998,000 in 2004 and 2005, and Russian demographers generally accepting estimates in the 200,000–400,000 range as of 2004. Temporary migration and shuttle trade conducted by Chinese merchants are most prevalent in Russia's Far Eastern Federal District, but most go back and forth across the border without settling down in Russia; the Chinese community in Moscow has a higher proportion of long-term residents.
