The emirate was selected because of its innovative and inclusive application, with a community-focused activity programme containing creative proposals to engage the very large migrant population, a UNESCO statement said.
"I applaud the nomination of Sharjah as the World Book Capital as well as the efforts undertaken by the city in order to make reading available to as many people as possible, in particular the marginalised populations, as a motor for social inclusion, creativity and dialogue," Director-General of UNESCO Irina Bokova said.
The GCC countries include Bahrain, Kuwait, Oman, Qatar Saudi Arabia and the UAE.
Sharjah has been chosen for the quality of its literary and cultural activities, and for its unfailing efforts to make books accessible to the entire population of the nation, the statement said.
Sharjah is the 19th city to become World Book Capital. It was preceded by Madrid (2001), Alexandria (2002), New Delhi (2003), Antwerp (2004), Montreal (2005), Turin (2006), Bogota (2007), Amsterdam (2008), Beirut (2009), Ljubljana (2010), Buenos Aires (2011), Yerevan (2012), Bangkok (2013), Port Harcourt (2014), Incheon (2015), Wroclaw (2016), Conakry (2017) and Athens (2018).
