"Our proposal to offer visa-free travel to Ukraine is an acknowledgment of Ukraine's successful reforms. That is why it is important that Ukraine remains committed to continue the reform process," Avramopoulos wrote in an official statement.
However, visa-free travel does not afford the right to work in Europe, which has been so important for Ukrainian advocates of integration with the European Union, he added.
The new Kiev authorities that came to power after the regime change in February 2014 have made visa liberalization one of the top issues on the Ukrainian-EU integration agenda.
Progress in the visa negotiations has been the first sign of advance in the integration talks since Dutch voters rejected a draft Ukraine-EU association agreement in a referendum in April.
