Fifa has shelved its ban on international football matches played at high altitude.
President Sepp Blatter said Fifa’s executive committee had decided provisionally to suspend the measure.
“Let us reopen the discussion,” Blatter told a press conference here Tuesday.
The CONMEBOL organisation, representing South American football, has been demanding that Fifa drop its ban on playing matches above 2,500 metres (8,200 feet) until after the 2010 World Cup qualifying campaign.
Bolivia’s football federation claimed it was discriminated against, as the capital La Paz’s Hernando Siles stadium is 3,577m above sea-level.
Ecuador was another affected South American nation with its capital, Quito, at 2,830m.
Blatter said qualifiers for the 2010 World Cup can now go ahead at high-altitude venues while Fifa considers changes to laws for match conditions at international and domestic club level.
