So far, only the Los Angeles edition of FIAC—the dominant Paris art fair that follows Frieze in October every year—has been announced but The Art Newspaper says the 2015 event might be paired with one in Russia:

The organisers of the Paris fair, Reed Expositions France, confirmed the US edition this week. Fiac in Los Angeles is due to take place in April 2015 to coincide with Paris Photo LA, which launched in 2013 and which Reed Expositions also manages.

According to reports in the Russian media, Fiac in St Petersburg in 2015, is also being considered.

Fiac heads to Los Angeles and possibly St Petersburg too? (The Art Newspaper)
