At Apple's Worldwide Developers Conference earlier this month, Tim Cook announced that the App Store would be launching in 32 additional countries this month, bringing the total number of countries with App Store access to 155. As documented in the country-selection page within the iTunes Store, those 32 new markets are now available, although Apple has yet to update its support page listing which iTunes Store content is available in which countries.
The vast majority of new countries are located in Apple's African and Asian markets, with the exception of Albania and Ukraine in Europe. The full list of new App Store countries includes: Albania, Benin, Bhutan, Burkina Faso, Cambodia, Cape Verde, Chad, Republic of the Congo, Fiji, Gambia, Guinea-Bissau, Kyrgyzstan, Laos, Liberia, Malawi, Mauritania, Federated States of Micronesia, Mongolia, Mozambique, Namibia, Nepal, Palau, Papua New Guinea, São Tomé and Príncipe, Seychelles, Sierra Leone, Solomon Islands, Swaziland, Tajikistan, Turkmenistan, Ukraine, and Zimbabwe.
