On 1 January 2016, Ukraine joined the Deep and Comprehensive Free Trade Area with European Union, which aims to modernize and develop Ukraine's economy, governance and rule of law to EU standards and gradually increase integration with the EU Internal market. Then, on 11 May 2017 the European Union approved visa-free travel for Ukrainian citizens: this took effect from 11 June entitling Ukrainians to travel to the Schengen area for tourism, family visits and business reasons, with the only document required being a valid biometric passport.
