According to a latest report by Horwath HTL, Vietnam recorded the strongest growth in domestic tourism in Asia Pacific between 2013-16, driven by the growing middle class. The low cost carriers have also been a growth catalyst with Vietjet Air increasing its fleet size from 18 to 45 aircraft between 2014-16. Besides the world’s largest outbound tourism market, China is also leading the world in terms of domestic tourism, recording 4.44 billion trips in 2016. In the first half of 2017, growth of outbound tourism slowed and an increasing number of Chinese tourists travelled domestically. The growth is driven by improved transportation with high-speed railways, flights and other traffic systems, together with innovated and upgraded travel products.
