The transport system was utilised by many during the FIFA Club World Cup in December.
The expansion of Qatar’s Hamad International Airport is also planned to accommodate some 50 million visitors a year by 2022.
Former Cameroon international and Barcelona player Samuel Eto’o, who serves as a global ambassador for the SC, said he was “sure fans will find many interesting places to visit when they arrive in this magnificent country in 2022”.
“I like the people in Qatar, they are open and sincere,” Eto’o said in an interview with the committee.
“I also like the fact you always feel safe and secure in Doha and throughout the country. These things should offer football fans a level of reassurance when they come to Qatar for the World Cup.”
Hassan al-Thawadi, secretary-general of the SC, said it was an incredibly important World Cup – “for Qatar, the region and the world”.
