(150825) -- BUENOS AIRES, Aug. 25, 2015 (Xinhua) -- Chinese dancer Ping Yu and her Ukrainian partner Sergiy Podbolotnyy dance at the semifinal of the Tango World Cup in Buenos Aires city, Argentina, on Aug. 24, 2015. Tango is sweeping across Argentina's borders, taking Asia, especially China, by storm. This year's key competitive event, the 2015 Tango Festival and World Cup, which is being held Aug. 14 to 27 in Argentina's capital Buenos Aires, features couples from around the globe, including a Ukrainian/Chinese couple. Ukrainian-born dancer Sergiy Podbolotnyy and his Chinese partner Ping Yu, who have been competing together for some time, have decided to rent a salon during their stay in Buenos Aires, so they can continue to train in the lead up to the elimination rounds. Competitors this year have come from more than 40 countries and regions. The rising interest in tango in the East is one reason for this growing event. (Xinhua/Martin Zabala) (zhf)
