European Union Commissioner Johannes Hahn has warned Kosovo opposition members that blocking Parliament will hamper the country's further integration into the 28-nation bloc.

Hahn was visiting Kosovo on Friday, which last week signed a stabilization and association agreement with the EU, considered a milestone for its economic growth.

During the last two months, the Kosovo opposition has disrupted Parliament using tear gas, whistles and eggs to demand the government renounce deals with Serbia that give more powers to Serb-dominated areas of Kosovo, and with Montenegro on border demarcation.

Although warning Parliament against holding other sessions, the opposition let Hahn speak, allowed a vote Monday and last week let the Austrian president speak.

Kosovo declared independence in 2008, a move not recognized by Serbia.
