MOSCOW -- Spain's Rafael Nadal, the world's top-ranked tennis player, was a celebrity representative Friday of a vendor at the Moscow Millionaire Fair, an annual event that attracts some of the wealthiest people on the planet.

"Moscow's not like Ibiza, it's a lot colder," Nadal, who traveled to the Russian capital to promote the luxury houses of Ibiza-based Vitaeibiza Homes, told Efe.

The 22-year-old Spanish tennis star - who was born in Majorca, which like Ibiza is part of Spain's Balearic Islands - arrived Thursday night from Madrid and has since had time to make his first visit to the Red Square, which was covered in snow.

A throng of journalists met Nadal upon his arrival at the Crocus Expo fair complex, where more than 200 Russian and foreign companies have been exhibiting their luxury goods - everything from cars to yachts to helicopters - amid tight security measures.

Besides Vitaeibiza Homes, other Spanish companies present at the fair, which runs through Sunday, include Basque jeweler Damaso Martinez, property development and construction company Construcciones Hispano Germanas, S.A. and luxury furniture brand Coleccion Alexandra.

Vitaeibiza, which organized Nadal's trip to Moscow, specializes in the construction and sale of environmentally friendly homes that blend into the natural surroundings of Ibiza.

The event - the last edition of which attracted more than 40,000 people and over 200 exhibitors of luxury products worldwide - was founded five years ago in Amsterdam as an event for advertisers and readers of the Miljonair magazine.

Since then, the fair - first held in Russia in 2005 - has become a fixture on luxury event calendars.

In April, the Russian edition of American business magazine Forbes reported that the number of Russians with fortunes exceeding $1 billion had nearly doubled over the previous 12 months to a total of 110 people.

Moscow is the city with the most billionaires, 74, topping New York and London, with 71 and 36, respectively. EFE
