In the Chinese Civil War, the Soviet Union had a tumultuous yet strategic relationship with the Kuomintang-led Nationalist China until 1949. In the Second Taiwan Strait Crisis, Soviet leader Nikita Khrushchev recommended the internationalization of the Taiwan Question and appealed to the United Nations and other multilateral organizations to intervene. The Communist Party of the Soviet Union called for the Ten Nations Summit in New Delhi to discuss the issue on 27 September 1958 as one of the precursors of the later Sino-Soviet split. Since the formation of the Russian Federation, Taiwan has exported many ferric materials to Russia in 2004–2005. In 2005, the total amount of the trade between the two economies was $2,188,944,473. Russia has a representative office in Taipei, and ROC has a representative office in Moscow. Russia keeps a positive balance in its trade relations with Taiwan mainly from crude oil, cast iron and steel, nonferrous metals, petrochemical products, ferroalloys, coking coal, timber, and chemical fertilizers. Russia imports mostly electronics and electronic parts, computers and computer parts, and home appliances. The two countries established unofficial diplomatic relations between 1993 and 1996. Taipei is targeting Russia for exporting opportunities and marketing potential.
