Tango lovers from around the world are descending on Buenos Aires for the World Tango Championship. The annual event draws at least 400 couples from as far away as Japan and Britain.
Tens of thousand of people visit Buenos Aires every year to watch the dancers compete. It has become increasingly international since its debut in 2002.
There are two categories in the tango championship: stage tango and salon tango. The winners in each category will take home a prize of five thousand US dollars.
The Championship final will take place in the city's Luna Park next week. This year's championship was declared part of the world's cultural heritage by the United Nations in September 2009.
